MDA2 Carkit is silent after upgrading ROM

Hi,
I've got a problem with my carkit (O2 XDA-Carkit) after I upgrade to the new ROM-Version of T-Mobile (1.60).
With the old Rom-Version, the carkit works as a loadspeaker for all kind of sound. The voice-instructions from tomtom for example, came out of the carkit-speaker loud and clearly. Each kind of sound, the device made, came out of the speaker of the carkit.
Now, after upgrading to the new ROM, only the telephone works with the speaker of the carkit. With Incoming or outgoing calls I can use the carkit as usual...the speaker works and the mikro works also. But every other sound (e.g. tomtom voice-instructions) came direktly out of the speaker of the mda2 in a poor quality.
Some hints, how I could use my carkit again as a speaker for all kind of sound without goinig back to the old ROM ?
Any other kind of hints...maybe to use a bluetooth headset therefor (so that all kind of sound came out of the headset....not only telephone...I've got a Plantronics Headset...but also only the telephone works)
thx for help
best regards
rob.

Yep.......I have the same problem here.......don't know why they changed settings on the handsfree profile here.
Another thing you will find out is that the charging is very slow on the XDA carkit with the XDA II. If you run TomTom, Yeti and a bright screen the xda II will not charge, but drain!!
It has something to do with the wiring of the interface, but unless someone will come up with a solution I will go for a new carkit or a BT solution. (It's a bloody shame though it doesn't work properly with the XDA carkit! :evil: )

Hi,
the charging-problem is also a mess.
I think, the problem is only the GPS-driver from tomtom. In my tests, only when the GPS-driver is loaded, the battery-power goes down. With stopping the GPS-driver, the battery will charge again, but only, if the battery-power is more than about 75 - 80%.
If the battery is less than 75%, it will not charge at all, even if, there is no App runnung and the screen is off.
You said, you will go for a new carkit or bluetooth-solution. Do you know a carkit or bluetooth-solution, wich offers the feature, that all sounds (tomtom instuctions...etc.) came out of a loadspeaker or thru a headset (without connecting the wired headphone ;-)
As far as I know, at the moment all devices works only with the telephone-funktion....
best regards

Same here,
i have build my own carkit, and have put ground to pin 19,
sound was normally going though the connector to my car stereo
now it doenst anymore :evil:
I am sure this isnt a hardware thing it is software
could be the settings on the handsfree profile. on the xda2...
this is very very frustrating. just being finished with my carkit and now i cant use it anymore
also you cant set the phone to speakermode anymore..

I am sure this isnt a hardware thing it is software
could be the settings on the handsfree profile. on the xda2...

Does anybody know how to change this back?

I found that the registry points to a certain file in your windows directory: HandsFree_Dll.dll
(I found this here: HKLM\Services\Handsfree)
Can someone with the old 1.03 ROM please upload this file so i can try if this solves the problem...
TIA,
Max

Akira, Max :
I am building my own car kit, and have no success.
I do not obtain audio out with or without grounding pin 19.
I'm running Rom 1.60.00WWE.
Did you solve your problem ??

I must correct my last update.
I obtain audio when in phone mode, but not during playing waves or TomTom directions. Even Ring Tones do not go out trough the bottom connector.
So is it a software problem ?
Can it be corrected ?

MDA compact ./. THB Bury Carkit: Problem with Patch

HI everyone,
first post
There is a Patch for enableing the THB carkit to provide a proper muting of the radio. This patch is really slow. This means that it takes at least 2 sec. to mute the radio. This is no problem while using the phone, but it is while using TomTom Navigator.
Now heres what I hope you can do or already did:
Either maybe someone has a better (faster) patch or maybe it is possible to let the TomTom application somehow never use the tel. mute function so that the build in speaker is used.
Thank sou for your answers...
best,
ben

nobody?
Thank you all anyway....
best.
ben

So, what is this pacth doing exactly? Where do you got it from?
For which car kit is ths patch?
I`m using a THB Bluetooth Car kit, but without muting radio, so i can not test it or say anything about it...
Stefan

Thank you for your reply,
the patch is for the dedicated phone specific cradle wich is available from THB for the MDA compact. The pacth is obviously needed for muting the radio at all. In fact the car kit doesn´t recognise the phone "is in a call" without the patch.
Heres my actual idea:
It seems that only some kinds of audio files are supported for beeing routed to the car kit. E.G. an *.wma doesn´t activate the muting even with the patch. So I´ll try to convert all TomTom5 announcments into *.wma so that they are not routed to the car kit and therewith don´t mute the radio. This is, if it works, an easy and acceptable workaround.
I´ll post wether it worked later.
I´d appreciate anyone having a better or diffrent solution and posting it here.
best,
ben

Hi Ben,
I'm still waiting for my THB carkit and cradle, so I can't help you at this very moment.
What I wanted to know about this kit: is it possible to play music via the radio??

Playing Music
Hi corny749,
you actually are able to listen to music with the carkit. Unfortunately the music is filtered just as a phonecall is by the blackbox. This means that the audio frequencies are not transmitted linear. So the music doesn´t sound very good.
However I hope to here from you in the future. Maybe you´ll find a solution for the patch problem.
best,
ben

Car kit - Permanent audio out?

Just bought this car kit http://www.expansys.com/product.asp?code=109748 for my Qtek 2020i (Alpine)
Pretty comprehensive kit for the money. 8) Comes with control box, speaker, mic, loom for connecting to car stereo system.
I was wondering if there was any way to put the audio of TOMTOM or media player through the car kit ?
I have read about the 10K resistor mod which i tried with another active holder i have but that didn't seem to work :roll:
I thought there may be a utility that could fool the PDA into thinking it is in a call and sending the audio through the car kit, but when in a call all other audio is muted.
Are there any other work arounds getting TOM TOM / media player to output through the car kit?
Thanks

I upgraded my 2i to the latest official rom and when i put it in my cradle (looks the same as yours) I couldn't hear any tomtom directions unless i had the external speaker connected to the control box (haven't got mine wired into my stereo so don't know if the voice would come thru the car speakers).
I found that there was a slight delay on the instruction (cut off about the first 1/2 second) and that it kept losing the sat lock (using rikaline wired receiver) every 10 mins or so. Didn't try it with a bluetooth receiver.
The latest official rom wasn't for me (improved blackberry but i don't use it) and I reverted back to pugs one with the camera fixed and the o2 junk removed - now the voice only comes out of the pda's speaker but i don't lose the sat lock at all. There may be a registry hack that'll send the sound thru the speaker but I can't help you with that.
Not a lot of help. Sorry

How hard is it to upgrade ROM's for a beginner, done pc bios flashes b4, but this sounds more complicated.
Is there a fools guide?
are the official ROMS on here?

Don't know why that posted twice - sorry.
Before you upgrade rom backup your data (i use sprite backup and go to the advanced options to select "create self restoring" ones). If you're not worried too much about losing the data already installed then you can use activesync to create a new partnership (you'll have to do this anyway) and restore your contacts from there and any software previously installed.
You have to be careful with tomtom as I seem to remember that after a rom update it sometimes asks you to re-activate it and as you can only do it twice (i think) in 6 months you could end up playing email tennis with tomtom support.
The actual rom upgrade is easy ( I've never encountered any problems but use the search to read up on the procedure before going for it) - just remember to leave it in the cradle with the mains adapter plugged in as well and follow the instuctions.
The only minor hiccup i've had is that the rom upgrade wouldn't run first time round but just clicked on run again and it was fine - good luck

Yeah I have heard that about TT, I am a bit reluctant to upgrade the ROM, seen a few posts "pda dead after rom update HELP!!!" :roll:
Surely it must be doable without all the faffing, hopefully someone will know of a reg hack or a util that will do it!
Thanks for your advice.

You would have thought TT would automatically stick the audio out of the car kit :roll:

Had a look inside the car kit and it's micro circuitry tiny surface mount stuff!
That pretty much puts thying the 10K resistor out of the window. Too small for my big numb xxl hands

Headset problems.. plz help

Hi, the headphones that came with my Cingular 2125 (HTC Faraday) doesn't work in my phone, but works in everyone elses phone that i try, and that A2DP program doesn't work either with my bluetooth handsfree set either... any help on either one of them is much appreciated. (bought my phone off ebay and they may not be the same headphones that come with it, but it fits and works in any other phone i try...)
Thanks a lot.

Did you install the a2dp patch?

no, i didn't know their was one. im going to look for it now and see if it solves my problems. but it may be my bluetooth. i have a Motorola H3 bluetooth headset
edit i installed the fix and when i go to settings >connection> bluetooth> Menu>Devices>Motorola H3 i get the option of headset but i cant hear music through it. do i need a different media player?
or is there any way to get my phone to recognize the orignal headphones it came with.

The motorola h3 isn't an a2dp headset. I'd suggest the motorola s9, which is absolutely the best I've ever tried (and I've tried alot), but expensive. with an a2dp headset, you'll get an options for "headset" and "wireless stereo".
You can get music to go a non-a2dp headset, but it somewhat of a pain, and sounds like crap anyway.
But it is wierd that your wired headset doesn't work w/ your phone. when you plug it in, does it automatically switch to 'headset' profile?

@ dm251z, nope it doesnt automatically say headset or switch into the headset profile nor does it allow me to select it.

I suspect that there is hardware problem, but of course I have no way of knowing. normally, you can stick just about anything into the headphone jack, and the phone will automatically switch to headset profile (I just tried sticking in an adapter w/o headphones, and that switched it). I don't think that that profile can be switched manually, only hardware controlled. So maybe the headphone jack is shot.
sorry I can't be of more help. I guess I'd suggest trying stereo bluetooth. You can't go wrong with a decent bluetooth headset...even if the phone is shot, you can still use the headset with your next phone. Also for the a2dp patch to work, make sure that your phone has the latest ROM installed, or at least some version of aku 2.x
good luck.

ok. thanx alot for all your help. i even tried a friend of mines adaptor and it didnt work either so i guess ur right. o well. thanx again.

Bluetooth Handsfree Connected, but no sound

Hi if someone can help me it would be much appreciated. I just bought a Touch Pro and everything is working fine....except for one really annoying issue.
Whenever I connect my bluetooth to a headset, it shows connected but no sound is coming out. The sound is muted. when connected to my Audi, I see that the phone has bars (shows connected and I can dial the phone), but when I make a call no sound. Similarly on my SE HBH-DS970 headset. The A2DP works perfectly, but when I make a call nothing.....I've searched google and through XDA and no solution.
Can someone suggest a solution? I've soft/hard reset the device already. If I should change Radio ROM which one would someone suggest that's stable? Thanks

If no one else has this problem, can anyone at least suggest to me if this sounds like a Hardware or software issue? If hardware I will return it, but if software I will try to find a solution. Like I said the phone connects to BT, but I just can't get handsfree to work. File transfers and A2DP work. Thanks

Just flashed to UK ROM and still no help....I've read some people having the same problems over at the Diamond thread...I'm the only one answering my own thread here hahaha....if anyone can help I'd greatly appreciate it. Thanks.

Hi,
I occasionally had such an issue with my Parrot CK3100, but I did not get the time yet to investigate further. After the call was connected I did not hear anything, and I am not sure whether the other party could hear me.
On another day, the handsfree was working perfectly OK.
Cheers
Michael

Thanks for replying Michael....I'm at a loss and I tried all the suggestions posted. I hope it's a software issue...I'm going to buy a bluetooth headset tomorrow and see if that works. It's not the end of the world, but annoying since all my ppc, s60, BB, and UIQ phones prior to the TP have not had any such issues.
Do you think it's a software issue?

have you tried playing music?

Yes.....A2DP works perfectly....no problems whatsoever with file transfers either....I'm guessing either it's a software problem or the phone has a new bluetooth software that's not agreeing with my older SE headset, but the car is another issue. The Car is 2007 and I'm sure the Bluetooth software is not that old. I've tried Euro WWE and Asian WWE ROM and no go.....I'm going to try the Cingular ROM and see what happens.

Just another quick update....I tried 2 other different bluetooth headsets and still the same problem... for some reason the sound for handsfree will not come through...anyone know of registry hack possibly that will allow sound to come through?

May not be entirely related to your problem...
Mine is worst...whenever I have paired my Jabra or iTech BT headset, when the phone rings, 8/10 times the phone will auto pickup (and no I did not setup the phone to auto pickup) and the it will NOT connect to the bluetooth. Instead it will be just like an auto pickup and the sound will come thru the phone headset. This is driving me nuts!!!!
