I have just a new parrot 3200 LS color installed in my car.
Pairing with Diamond is no problem.
But the connection is not stable; every now and then the BT connection drops; sometimes the parrot seems to do a reboot.
My wife had a Nokia N70 with the same problems on my carkit.
firmware of the carkit: 2.11b (Dutch)
Diamond radio: 1.00.25.05
Any tips?
same problem
hi!
i have also a parrot car kit, not the same but the same problem. the bluetooth connection is very instabil and so sometimes it is hard to phone with them...
there are any solutions fpr these problems?
thank you all and sorry for my english.
I updated the radio in my Diamond to 1.00.25.08. But this does not solve the problem.
I was just wondering whether the number of my contacts (> 500) could be the cause of the problem.

it definitely does not depend on the number of contacs, as long as you cannot use your contact in any other way as calling them with you car kit ;-)
Regards
I wondered about the number of contacts, because it takes very long (> 20 minutes) to sync my DIamond contacts to the carkit.
All contacts are stored in the carkit; so I could imagine that somewhere a bufferflow in the carkit firmware could occur.
have you tried not to sync every contact, but let's say 20 and id you try it then?
Have you tried flashing your Parrot with the latest software update? I was having a problem with my CK3300 and that solved it. It is easy to do via BT on your laptop
According to Parrot's web site 2.11b is the latest firmware
I also have an 3200LS paired with the diaomd; but experience no problems at all.
I've tried lots of ROMS also; and each and everyone works well....

I also have a lot of problems with this combination, though it used to work fine. Don't what I did to mess it up, but I did...
Mouragio, could you post your BT settings?
Using the Advanced Configuration tool, my current settings are:
- Obex: Disabled
- Use Joint Stereo: No
- Bitpool: Default
- Maximum supported bitpool: 0
- Minimum supported bitpool: 0
- Sample rate: 48000 Hz
- Audio gateway service: Disabled
- Audio gateway power save: Enabled
I have maybe a partly solution to this problem.
I have more than 500 contacts in my DIamond which are synced with the parrot.
After you for the first time pair the phone with the parrot, it requests whether it is allowed to access the contacts on the phone. I answer 'yes' on the phone.
Now the syncing starts. This lasts very long (more than 20 minutes). When you interrupt this syncing by for instance switching of the ignition of your car (after which the parrot 'says' goodbye on his screen), the parrot seems to go mad.
You have to delete the paired phone on the parrot, pair again, and let the syncing of all contacts finish. After that I had no problems any more with my bluetooth connection between phone and parrot.

Been there, done that... Didn't work for me... Syncing still seems to last forever, but sometimes it syncs within a few seconds...
I also have another problem; the BT connection is dropped after each phonecall, incoming or outgoing. Sounds familiar to anybody?
Also with me the syncing process is still strange. After I've made or received a phone call, and this call is ended, the parrot starts syncing. SOmetimes more than 30 minutes.
But after I let finish the syncing the first time after I paired the phone and parrot, I have no problems anymore with dropping of the bluetooth connection between phone and parrot.
I want to test the following:
o delete pair
o create new pair
o disallow syncing of contacts
o create VCF file (via parrot_vcf_creator.zip application that can be downloaded from parrot website) that holds your outlook contact
o send that file to the parrot.
So you have the contacts in your parrot, but they will not be synced anymore. Maybe this can 'solve' the syncing problem.

I have tried searching the forums and can't find much Info.
Is anybody here using the above system for telephony & GPS; If so how do they intergrate/do they work well on the XDA II (I have ROM Version 1.72 with Radio1.17)
I Know about the headset profile probs not giving full functionality of the Handsfree use of the car kit but this doesn't bother me to much as long as I can Make and receive calls.
Thanks in anticipation!
I was going to get a CK3100, but heard so many problems regarding build quality, and lack of support, I got a HCB 30 instead.
It did not help when I tried to e-mail parrot for advice and 3 different e-mail adresses bounced back.
Works Perfect!
Just had the CK3300 installed today and it works perfectly - I Knew some of the functions didn't work because the XDA2 only supports headset profile but once you have transferred your contacts to the kit via bluetooth it works well.
Also the GPS works well with CoPilot 5 live; it picked up the signal straight away ; well pleased with this set up!!
same to me have the ck3300 tested with qtek2020 - works fine. problems with 9090 but after bluetooth update now it works fine. No tests with S100 at this time.
tested GPS with destinator 3 and map&guide fleet navigator and mobileobjects fleet management system.
don't use bluetooth tools after Rom 1.66 :!: CK3x00 didn't work aber installation of this

Any tips on setting up the CK3300 with my XDA2?
Just had the car kit fitted - i need both nav and handsfree functions - but i am not sure that i have got the phone and ck3300 to bond properly. So everything is 'greyed out' on the parrot.
Using ROM 1.72.00WWE (1.72.181) and radio 1.17.00
Thanks for any help received.
If everything is greyed out then it isn't bonded properly!
Step 1
Delete the pairings you have from XDA2 and car Kit;
Step 2
On the car kit turn the control knob untill settings appear- then scroll to 'Advanced Settings' - 'pairing a telephone' - 'windows CE device'
Step 3
Now search for devices using your XDA2 and the car kit should be shown.
Step 4
Enter passcode 1234 and accept headset and serial profiles when shown.
PAIRING COMPLETE
to access your phonebook you need to transfere the contacts via bluetooth to the car kit.
Hope this helps
XDA2 CK3300
Managed to get the GPS set up (fiddling with COM ports - even imbeciles strike lucky sometimes)
Some items are now in black. However, I am not sure that I have done it right as I cannot get it to use my phone to make calls or receive them. Which is exactly why I bought it in the first place.
So, please (please please) can you tell me how to exchange my phonebook?
I am going to sit in the car right now and have a go at your bonding advice...maybe all will become clear (but that is not often my experience!)
Thanks again for your help.
You need to bond the phones in the manner I described or it will not work ; this is clearly ststed in the Parrot instructions and on their website.
(I have noticed a strong correlation between people who do not read instructions and complain things do not work!!) - Joke
You also need to make sure your headset profile is active on the XDA 2 for it to work. Again reading the instructions for the phonebook - you tap and hold a contact on the XDA2 and select 'beam contact' - 'via bluetooth' the bluetooth search then comes up and the car kit will be found you then 'tap to send'
Now i have the opposite problem!
Believe it or not, I have now got the XDA2 and the CK3300 bonding automatically so I can make and receive calls whilst driving. It works pretty well (occasionally makes an awful noise, but only occasionally). I am impressed.
However, once I had done that, the GPS is undetectable. I have tried all sorts of combinations. I have checked the instructions - and selected the long code (ends in 9600) but I am not certain that I am using the right com port. I have tried most of them without success.
Oddly, this is the one thing that WAS working before I got the car kit to work (for calls). Somehow, either I have lost the right settings OR the XDA2 won't do both (although I read somewhere that it would) OR my ROM needs updating (uh?)
Please help.
BTW, I am due a phone upgrade - I love the xda2 but would consider getting another phone if necessary, if anyone can recommend one that is fully CK3300 and TomTom compatible.
I don't use Tom Tom myself but from reading these forums I think you need to install the patch on their website to allow Tom Tom to use the correct Port .
Your Car Kit also needs it's software updating if it makes a noise like you say. On the Car Kit go to > settings-advanced settings-information and you will find the software version (sounds like 4.03) if it makes a noise. The latest on the Parrot website is 4.10b and this will fix the noise issue.
If you need help installing this let me know.
The best Phone is surprisingly the Old Fashioned Nokia 6310i - it has a good bluetooth stack and uses the handsfree profile rather than the headset so contacts sync automatically but if you require live traffic info best stick with what you got as the Nokia will not pair with the XDAII and the car kit at same time.
Which COM port?
For the moment, I have a temporary solution.
However, I have updated the TomTom Navigator software and the GPS, but still don't know which port the GPS in the CK3300 should be connected to.
Any ideas?
And, thanks Nikpro for the excellent help so far - you are a true altruist and a star!
The outbound port on the xdaII is port 5 by default
On XDAII go to Settings - System tab - Bluetooth settings and make sure you check the tick box for outbound COM port.
There is also a chance you have deleted your serial port profile so tap on the bluetooth icon in the Today Screen and go to bonded devices. Select the CK3300 and delete partnership (do not delete pairing from car kit end!)
Then search for new devices from the XDAII and the CK3300 will again come up; create a new partenship and everything should be good.
Still having problems
Oddly, I still cannot use the GPS on the CK3300.
I am using my old TomTom at the moment for GPS and the CK3300 for headset - which works fine, but I wanted the CK3300 to do both.
When I try and reset the GPS to the (series of numbers ending in 9600) as stated in the info and the instructions (Nikpro, take note - I have read them - but your comment made me laugh), the TomTom just 'freezes'. Wait - and wait - and wait - and when it reincarnates itself, no GPS at all.
I am using the 1.72.00WWE rom and radio 1.17.00
I think that I have tried every permutation for the COM port.
Has anyone any ideas? Please?
When you initially pair your XDA to the car kit do you get a message about serial connection show on the screen? The problem must be with the tom tom software as with copilot and mapopolis it works fine? or the way you are pairing the two!
What software version is the car kit? PLEASE DESCRIBE HOW YOU ARE PAIRING THE DEVICES??
Hi all, 1st post and all that.
Have you tried falshing the parrot with the newest rom, mine picked up enough to make and recieve call, but i flashed my xdaII with 2.02.T1WWE this morning and it works even better.
Hope you get a result

Use Bluetooth tools www.bluetooth.jazztel.es
and edit the registry under hkey local machine, builtin, BTIBserial, rename BTIBserial.dll into BTIOBserial.dll
and go Start, Settings, System, Bluetooth settings and check both inbound and outbound.
Delete ALL paired devices, reboot, and re pair them.
You will now have an option for two serial ports, one for each device.
This is the only way to do it if you have two devices that need a serial port. If you have a third, you are SOL.
Normally, the stupid programmers who made the MS BT program, made it so it only had one dynamic port for BT. Some people would experience having to reboot before switching BT devices, most would have to re pair every dam time.
The new 2005 does not have this problem but it has other bugs.
They smart people at MS changed the databases so Mapopolis and other third party programs can not read the contacts or have other bugs with them. Plus the 2005 version here limits your memory.
The 2.02 - 2.06 will NOT work with Hands Free and most car kits need it and if you have caller ID via BT, you are SOL too.
The 2.20 is a stable and a good OS and the Hands free works much better. The down side is, when I get a call on the call waiting, even if I did not answer, it would disconnect the BT headset and no sound through the phone too. I would have to, click on Tools, Hands Free off, tools Hands
Free on before it would work. I have lost many clients this way.
I decided to disable call waiting in the phone settings and it only has a few bugs now like I have to turn off and then back on the BT headset after ever call or it would revert to Headset mode.
The caller ID will not display if the call is in the history of my BT headset or if it is in my contacts database.
I mention my BT headset because it is like a car system when used in Hands free mode.
Good luck, let me know if you have any trouble now.
Parrot 3100 with XDA II
Hello,
I have just put in a Parrot 3100 and it works fine as a handsfree phone.
is there any way when I am not in the car though to use my Jabra 250v headset without rebonding and selecting it as the preferred headset device?
I can't seem to switch between the Parrot and the Jabra when the other one is not in use without repairing.
Thanks for any advice

Try turning of one and turning on the other and soft reset..
Ok, I have just spent my entire weekend trying to get my Qtek 9090 to communicate to my newly installed Parrot CK3300 (with GPS). I have read the manual about 3 times from beginning to end, know the whole website parrot.biz by hard (ugly site BTW), and have tried about everything in configuring, but with no success so far.
Initially I had the 2 devices paired to each other, but after I installed Tom Tom 3, it is impossible for me to get them to pair again. Nevertheless, the 2 devices "see" each other (when asked in "Linked devices"), but they can not get to communicate. From all the stuff I have read on forums and sites, it seems that I need to upgrade my Bluetooth version, but I have no idea how and where to start this procedure.
Can anyone help me out here ?
Any tips are welcome !
Since v1.60c my bluetooth second binding/connection is distorted.
In the car, first my TomTom gps binds and connect perfect and then my carkit Parrot 3100 binds and connect perfect. But when i make a phonecall, the line is very distorted. Some buzz is on the line.
And if i change the sequence, by first binding the carkit, and after that trying to bind the TomTom gps. The gps will not bind at all.
The last version that worked correct was the version 1.60c
Somebody with the same experience?
PS. is it possible to extract the Bluetooth files from the v1.60c version and save on the latest versions?
Gps & Parrot Together With Wm2k5 : Bluetooth Incompatibility ??
Same happens to me.
I'm experiencing this problem since I upgraded from WM2003SE.
Every WM2K5 ROM I've tryied does the same.
If once gps and parrot both are binded, you go to bluetooth settings/devices/and you disable hands free service, wait for few seconds and enable it again, then the parrot should work with no trouble.
It's the only that works to me...I have to do it every time I get in my car.
If somebody has the solution I would apreciate.
FRANCESC
Yes, it works for me too. But it isn't a beautiful way to connect!
Somebody know what this could be?
hi
could the both of you with the parrot 3100 please tell me:
.) does it sync the phonebook with pda's contacts?
.) does it show the name of the incoming call?
.) does it show mobile providers net status (=strenght)
if not: have you tried www.jetwaremobile.com ? does it work with that "enhancement"?
thanks!
regards ize|man
I will try!
Thanks for this information, I'll try.

Not working for me!
I think that I'm suffering with the same problem. I used to use a Nokia CK-1W for hands free and a iBlue BT GPS with Tomtom6 on my Jasjam/Dopod/Hermes and had no problems whatsoever. I've just changed the car and have fitted a Parrot CK3100 (FW 1.6C) and I can no longer connect to hands free and the GPS at the same time.
If I bind to the GPS first everything is fine until I attempt to pair with the Parrot. Upon pairing synchronisation starts and then for some reason the bloody thing starts to make a call!!! The phone doesn't recognise that it's calling, it's just the kit doing it. Once paired and synched the GPS connection is killed.
If I bind to the Parrot first I have no bizarre calling issues but I am unable to locate the GPS device.
What the hell? Have I bought a turkey?
Anyone with a suggestion as to how to fix it?

so. none of these three questions is answered with YES? does it work out-of-the-box?
so if i get you right: there is no way to sync my contacts with the 3100?

I mean it's not solving my problem
Didn't solve mine either. In fact, it made it worse! I still have all the connection problems but in addition, the battery meter no longer shows on the Parrot. Uninstalling jetware returned the meter.
Hi There,
I have a HTC Cruise (dutch) and a Parrot 3200 LS-Color bluetooth carkit.
My carkit sees my HTC and I can sync my address book but when I receive a call ore when I want to call it doesn’t work right. I have to put the telephone to my ear again. The speakers en mic in my car don’t work.
Can any one help?
Thanks,
marco
update your carkit
Are you sure that you are on the best firmware for your car kit?
I have a diffrent parrot car kit (mk6000), and all my pb was solved by: going to the last parrot firmware, and after updating my phone to WM6.1 (not sure that this second is necessary or not)

I have a Parrot CK 3100
Version 4.16
I have also HTC TC with WM6 original
Every think work fine
You can try the jetware bluetooth extension.

My Parrot works fine with Polaris
Parrot 3100 working fine with Polaris here too.
I had posted my experiences with the new firmware update here:

Hope that this helps

imo the parrot with the color screen is a waist of money, ck3100 is also more supported ! My polaris works flawlessy with my ck3100.
My Polaris works near fine with the CK3100, except the disturbing phantom call when your last call was not picked up...
The other minor problem is that the different numbers of one contact are shown separated (/H /W /M...) Does anybody know if it possible to show all together?
Parrot have a 4.17 update out.Try flashing your ck3100.

There is a prog on Parrot's website the creates a vCard of all your contacts in outlook this file is then sent to the CK3100 from your phone and all of you contacts are saved in the bluetooth kit.
I don't think the phone auto syncs these contacts though

Hi Guys,
I don't want to be rude, but the thread starter asks for a solution to his problem not a list of parrots which do work with the touch cruise. Not really helpful according to me :s.
Futhermore, I am also having a lot of problems with the Touch Cruise with the Parrot 3200LS Color. I installed the jetware bluetooth extension, which solved 99% of my problems.
The 1% left is disconnecting a phone call. If I push the red button on the Parrot device, the call is not disconnected. I have to push the red button on my phone to end the call, but still the 3200LS thinks the call is still going on. I have to pull the plug to reset the 3200 LS. I already flashed the parrot with the latest firmware.
Anyone any useful pointers?
Parrot and TC
Hi there!
I don't know about you guys, but for me it's simple, for HTC touch, and for TC with my parrot CK v3.13 here's what i do:
- to be shore, you reset your parrot (red + green buttons, then you hear "please pair device", and only with first pairing),
- turn on your TC's BT, go to settings/BT, Add new device (Mode - visible), and when parrot asks for code, it's 1234, as i recall.
- now you are paired, and when you enter in your car only thing you have to do is to turn on TC's BT, pairing will be authomatic.
this works for me, without any problems...
Hope this helps

Portugal HTC user!!!
Hello
I use the "standard" Diamond (WWE ROM 1.93.479.3) with car handsfree set Nokia CK-15W. The PDA can be paired with Nokia, the connections can be made but other activities are impossible to get
I see in BT devices that Nokia supports only Hands-free Profile 1.5, not any others... But I also know (from Nokia's website & XDA) Phonebook Access Profile 1.0 but it has crippled it so it actually cannot do what is intended for.
I was unable to download contacts from Diamond to Nokia so I installed Jetware extension. It worked and the contacts have been transferred to Nokia in a minute.
Unfortunately now the car kit is almost unusable - for example:
- there is no calls history available
- I can't disconnect any call
- there is always "private number" displayed for incoming calls, no matter whether I have this person in the address book
- and many more.
I tried several different jetware configurations (enabling and disabling many features) but no matter what config I try the situation still exist. I also tried to reset both Diamond and Nokia.
Anyone can suggest something that may sort out the problem? Shall I uninstall Jetware after transferring the address book? Any more suggestions?
Hi,
I am using my HTC Touch Pro with an Opel Vectra built-in bluetooth carkit.
All functions, like browsing the address book and call registers, are working fine. However, at random times, my carkit reports no phone. When I then check my Touch Pro's bluetooth status, I see that it is has been disabled.
After manually re-enabling it, I can pair with my carkit for as long as it takes for bluetooth to turn itselves off again.
I've already tested with JETware, but that does not change anything. Also tried the universal broadcom bluetooth stack, but doesn't seem to work on the Touch Pro. HTC only comes with a standard answer that they don't support all carkits and headsets... Since the BT stack on the phone seems to crash, I don't think it's a carkit issue.
Anyone here with the same issue? And maybe a solution?
Thanks and regards!!
Start -> Settings -> Connections -> Bluetooth -> Timeout (tab). Turn off Visible mode set to "Never".
I think this must be your problem.
Hi Freco,
Thanks for your reply! This option is set. However it's not really the visibility that turns to invisible, but the whole bluetooth stack is being turned off completely. Need to fully re-enable it via Comm Manager.
Any other options? Does anyone know if there is a working broadcomm stack for the Touch Pro?
Regards!
Hi,
I have exactly the same problem with a Vauxhall kit, I have tried all sorts of things, but nothing seems to work
try:
start -> settings -> connections -> bluetooth
timeout tab
select 'never' from drop down box
Hi Brendo,
Unfortunately this doesn't solve the issue. Once paired, the connection even works without being visible. It's also not a fixed period of time before the disconnect takes place (can be within a minute, sometimes after half an hour). However, the whole bluetooth icons disappears from the top icon bar and comm manager shows it's turned off completely.
Hope somebody has any other ideas, because the only thing HTC can do is point to the carkit vendor :-(. Since all functionality is there when connected and the phone is turning off BT in some way, I really don't think this is caused by the carkit vendor. I should at least expect BT to stay enabled on the phone.
Thanks!
Yes, same here, BTW I have tried this in my Friends Saab, and the same problem.
same problem here with a Opel DVD90 buildin bluetooth carkit.
With other htc phones it always worked like a charm, but my mda vario IV continuously disconnects after a random time period and shuts down the complete stack.
Try this!
I have the same problem with my opel with original bluetooth-kit (2007). On the touch pro I changed the band and network from auto to GSM, as G3 reseption in this area is quit poor, especialy while driving. It helped for me, at least the last few days. I agree this has been an annoying problem.
I have tried to switch to "GSM only mode" in the past, but as far as I remember it does not completely solve the issue. However, I will give it another shot! Actually I can't figure out at what point it occurs... It can happen within a minute or after half an hour without using any funtion.
Does one of you know if there is a way to do some debugging on the Bluetooth stack?
And has anyone experience with other Windows Mobile 6.1 based phones in this combination (just curious if it's a WM issue or HTC only)?
Furthermore I did some tests with JetWare. You should be able to limit the number of synchronised items then (might be related to this issue). However, it looks like this configured limit is being totally ignored: when I limit my recent call list to 5 with JetWare, it still syncs about 25 items. Anyone tested with Jetware?
I have tried the GSM only mode, this didn't help either
I have now given up and got myself a Nokia E66, which works perfectly.
All contacts are pushed to car, no disconnects and AD2P works so my mp3 ringtones play through the car speakers! Sweet
Word of note, I had issues with N-Series phones, would connect ok, but contacts would not push.
I have the samen problem with my HTC Touch Pro and Saab.
bluetooth pairs just fine with my pioneer bluetooth enabled deck, but the problem iwth mine is once i receive a call sometimes no sound comes from the car, instead the earpiece is still on. but if i initiate the call first sound works just fine and earpiece on the phone is disabled, BUT once the call is ended bluetooth disconnects randomly and the phone takes a good 1-2min to reconnect. i absolutely hate the bluetooth on this phone!

I am having the same problems you describe. Anyone got an suggestions???
I encountered the same problem; first with an opel udp carkit and next with the bluetooth interface software from homeseer.
It has something to do with phone signal loss.
With the opel carkit I noticed bluetooth automatically turns off when the phonesignal switched from 3g to gsm.
I also noticed that in my home, BT turns off whenever I have been in a room with no phone-signal reception.
try this thread, both registry change and attached cab file, reset. DOn't worry if the make visible to all option is unchecked.
