The XDA2 connector pinout

every thing seems to be the same
though there are differences in the sound output
pin 19 must be connected to ground for sound through the connector
pin 19 cant be connected to +6v or else the whole xda2 is not responding anymore
pin 1 (mic) must be amplified
going to buy a small mic ampliefier on 12v tomorrow

Hmm, considering people still use their XDA I carkit, i suppose it should work...
However, the audio i tapped from the bottom connector is dead too...
Only hing i can think of is that HTC rewired it so the bottom connector only gives audio if you ground Pin 19 (Car_on).
If your 100% on pin 3 & 4 being #ground, they might have made audio mono, and switched pin 2 & 3, audio out on pin 2 and ground on pin 3. For audio that would still work...
Btw the headset-out is filled with a rubber piece, not handy for quickly attaching an audiopug i'm tinking of cutting it, but that's a bit drastic for a temporary workaround to use audio-out...

You took the words straight out of my mouth :?

All i really want is a Bluetooth handsfree profile !!! :twisted:

tomorrow morning ill try to get it working
maybe if i put +6v to CAR_ON it helps
the phone goes to speaker mode
maybe micfroon will work then to
audio pins are the same
so mic in would be pin 1
i think there is only a slight difference
audio was normally always been put through the connector
not it isnt anymore
**update
the connector is the same
the 19 pin function is different
+ will block every function of this phone, so thats the problem with my own carkit, i have connected it this way
- will send audio only through the connector
problem is now that i want to use a mic
when i connect a mic to pin 1 and GND, there is not sound
i know that pin one really is the mic, cause when i tap the tip of the wire while recording audio or test calling i hear ticks..
what kind of microfoon must i connect to pin one
must the same as the carkit version i think
or what connection will let the xda2 go into speaker mode auto
also there is no audio being put through the connector if pin 19 is not connected to ground
**update
also very intresting and maybe my awnser

I have the opposite problem, i want audio-out for a external speaker, but no ext. mic. (din't get one to work).
what kind of microfoon must i connect to pin one
One that doesn't want a wire to any power.
I bet one of an old nokai headset might work...
or what connection will let the xda2 go into speaker mode auto

Are you sure the wiring is the same, or are you just guessing ?

i am sure
i have tested loads of micrfoons
from nokia headset etc
external sound source is the awnser
i connected a mp3 player and it records fine
now i just need to make an external sound aplifiar for the microfoon
and set pin 19 to GND then its all done
got some old nokia carkit
maybe i can mod it

You mean you got te mic-in to accept audio, but only from an amplified source like a MP3-player ?
Here on xda-developers.com the said the mic-in should't be amplified...
But, hey, they can be wrong to...

when i connect a normal mic (tested 4 different ones) there is absolute sillence
when i connect my mp3 player and turn up the volume then there is sweet sound

Ok, talked to the techie-colleage today :
Headset mic is a condensator mic.
pulls approx. 1V (from audio signal)
What we need is a 'spool'-mic, they seem to be a bit more rare than te condensator ones... these pull approx. 0,6V His thoughs where to use a small speaker and test if it will work as a mic. Then try a real mic...
Or get a velleman kit with condens.mic and amplification

On XDA2 pin2 is NOT GND !

I agree with last post, pin2 in XDA2 is not conected to GND pins 5, 16, 17,18 (all them connected)
When I ground pin2, a little beep (wav) is heard, but nothing seems to happen.
Can anybody point what's the use for pin2 ??
I'm trying to build my own car kit with no success:
I can´t obtain audio out whith or without grounding pin19

I must correct my last update.
I obtain audio when in phone mode, but not during playing waves or TomTom instructions. Even Ring Tones do not go out trough the bottom connector.
So is it a software problem ?
Can function of pin2 br related to this ??
Anybody knows 100% XDA2 connectro pinout ??
myxda web page states that most of the accesories from xda1 will NOT work on xda2

PIN 2 IS ground, or the XDA 1 carkit wouldn't give any sound in combination with an XDA 2 !
The XDA 2 seems to give sound ONLY for phone be it through carkit or BT headset.
If that's true, and if that's the hardware on the XDA 2 then i want my XDA 1 back !!!

is there any solution yet to fix the bad audio quality at the connectors car_audio r/l ?

How can you with a Diamond HTC a car radio control as a kind of remote control?

Hello, my name is Marco and come from Germany, therefore, forgive my bad English. I have a simple question, how can I get from the HTC Diamond a remote control for the car-radio build? I can imagine with a Blue Tooth USB stick, because my car radio also has a USB port. Had this possible?
Yours sincerely, Marco

Do you mean that you want to control your radio with your phone or do you mean that you want to listen to the music from your phone at your radio, in this last case I would say FM transmitter

It should be possible, but there is one little problem and that is that your car radio isn't a Windows XP Driver-ready computer, jou will have to install drivers to the car radio for bluetooth usb adapter support and than it should work... Question is if this is possible..
You should buy a car radio that is bluetooth ready...

No, he wants to use it as a remote, next track, previous track, next radio station, vol up/down .. i think ..

i use the USB cable which came with the diamond and plug it into my car stereo which has USB port. You then just select Storage mode on your phone instead of active sync and it should recognise all the music folders you have in your 4GB internal storage.
Hope this helps

You can do it all with this model.

[Q] [REQ] improve Video Player + BT performance in Benq E72

Hi!
I own a Benq E72. Unfortunately my headphones broke, and they are not sold in my country. I tried making an adapter but it did not work.
So my only choice is to use a BT headset.
The problem is that BT+Movie player is too much for this phone.
I tried reencoding movies in all sorts of presets, using different codecs but I can not get a smooth play with BT.
I tried (and tweaked) TCPMP, CorePlayer, Divxplayer and Mplayer with no success.
I also tried overclocking the phone, but did not found any app that will work with OMAP v1030 (tried omapclock, XCpu Scalar and the like)
So, all that said, I am looking for any solution to this problem. So if you:
-Know a lightweight video player
-Have successfully solder an audio adapter
-Know an overclocking tool for OMAP v1030
-Know where to buy a headphone in Argentina
Please Reply
Thanks in advance!

Look at my old blog about E72 in my signature. The cabling for an adapter is there - when I had the device the adapter worked ok.

Tobbie!
Yes I read your blog, it was very helpful!.
I followed the instructions but the adapter did not work.
I used a Moto V3 adapter and modified it. It had a 100k resistance if I recall correctly.
I did not have a chance to get a 10k (All the stores are across town and closed when I go back home).
I even fooled around with the pinout but all I got was a CLICK! in one of the headphones. The phone did not recognize them.
Thank you very much for replying!

Did you notice that the headset needs also to be connected to the adapter - otherwise the device will not switch to headset mode. Pin 3 needs to be connected to grounds with less than 250 Ohms - usual headsets are in the range from 16 - 60 Ohms, so it should work. It did for me, so why not for you as well? And of course the headset must not contain a capacitor (which is very unusual btw.) but a straight connection.

The headset was connected. I will review the adapter, maybe the resistance was not right (I bought the V3 adapter on the street).
Unfortunately I do not know the headphone's Ohm-age, but I tried a few.
I really appreciate your interest and help

You have to remove all the crap that is connected to the USB for the Motorola handling.
Then you can start to use the naked parts that are left:
- USB
- MIC (not needed)
- 3.5mm headphones connector.
You must not keep the electronics for the Motorola handling!

Music control on phone for Car radio

Hello,
I have really no idea if this is possible, how hard this could be to do and what it can require but :
1 - Would it be possible when I plug my phone on my car radio with USB to control the music with my phone instead of the radio itself ?
2 - Would it be possible to deport the sounds (calls, applications etc) on the car speakers ?
Let me know if I'm not very clear
PS : please don't answer something like "use a jack-jack cable"
Thanks !

From what I get, you want to "stream" audio through the USB port. I don't know why would you want that and the jack-jack cable is not good (maybe you have a USB port on you car stereo but no line in) but as far as I know it would take A lot of modifications (stereo and phone) to make it work.
So, theoretically it is possible, practically I don't think someone will ever make it possible.

Im pretty sure it would be impossible to control the car radio with the phone via usb. There might be some kind of solution using IR, but I don't know how that'd interface with the Droid. Most aftermarket decks allow for a wired remote on the back (looks like a headphone Jack). I've used it with a steering wheel interface adapter and it worked well, so there is a possibility that a custom usb cable could be made, but would also require a custom app written for the Droid to output the signals through the usb.
On streaming radio via usb, I don't think that's possible either, bc the uusb on the deck is looking for files to read on a mounted drive.
If you happen to have an incredible, you can get the tv-out cable and make a shorting pin on the video output. This makes the phone think it's connected to a TV, and will then stream Pandora, music, Google navigation, etc through the usb. If you do this with your aftermarket radio, you'll need an aux input and an rca to 3.5mm cable unless you already have RCA.
Hope this helps!

Thank you for answers! I was asking that because I remember when I had an iPhone, I was able to play, pause, forward the music from my iPhone. I will try to use the aux-in (I have a little Pioneer DEH-3200UB).
Thank again !

That's because both the head unit and the iPhone know a common language and communicate.
Sadly, I don't think there's anything like that outside Apple.

It is called Ipod ready. That could be emulated in Android, would be another bite out of the apple,s ass.

Question OBD over WIFI and the Internet

I am a recent FYT user on UIS8581A, Android 11 (fake).
I have a sim card connected to it that provides internet. When I connect WiFi with OBD, internet connectivity is broken. WiFi without internet has priority in data transmission over SIM card connectivity.
Is there any way to configure or an application that will allow you to have internet from the SIM card and OBD via WiFi at the same time?

I asked this before buying and the answer from the seller made no sense, not trusting the answer as it seemed to be just selling their Wi-Fi OBD I went OBD BT and USB which both work.

I can't force BT to work. Whatever I try won't pair. That's why I bought obd wifi which works, but disconnects the internet.

Hands down best, no connectivity issues on my uis7862 FYT and fastest OBD throughput is genuine OBDlink SX - USB connected.

USB will work as long as you have an OTG adapter in the USB cable. BT will work as long as the BT OBD's name starts with OBD and you change the default pair code in the Head Unit to match that of the BT OBD. I have the OBDlink LX which is the BT version and that works well as does a cheap ELM USB.

Thank you very much for the explanation. I finally understand how Bluetooth works on this device.
Is it possible to disable this fake BT limitation?

1. What is the name of the OBD2 unit when in bluetooth
2. Do you know what the pairing code is for the OBD2 unit, have you changed the default pairing code in the radio BT to match the OBD2 unit pairing code
3. Are there any other BT pairings on the radio.

1: OBDII
2: ok it is 1234
3: yes, my smartphone

2. so have you gone into the radio BT app and changed the default to 1234 ?
3. Remove the phone from the pairing list, the OBD2 unit has to be the only one in the list until used at least once in the OBD2 app you plan to use, then and only then re add the phone.
Note that this could still not work even if you follow the instructions correctly.

Today I try to delete each pairing and do what you tell me.
Then I write the result here.
Thanks for now

I've never had to change my head units pairing code for my ELM OBDII Bluetooth adapter.
The OBDII uses 1234. It simply asks me when I pair what the code is and accepts it.

Obdlink SX usb for the win. Bin the chinese knockoff.

Yesterday I tried to pair by changing the radio name, password and all the craziest tests I could think of but nothing.
My bluetooth screen is the first photo I attach
When I try to connect one of my three working ELM327 minis, nothing happens, I touch the symbol of the chain to connect, it asks me for the pin of the ELM module, I insert it (it is 1234), after a few seconds a message appears "pairing succeeded". But that's not true, because the chain symbol doesn't change, in Torque I don't see the module (try various versions of torque) and I can repeat the bluetooth pairing indefinitely but it never works.
Any app I use for bluettoth tells me that bluetooth is not working or can't be turned on. But if I connect a smartphone it works.
I do not know what to do

Just a general comment.
The OBD connector is on the dash, the head unit is on the dash.
Why would you want to go wireless?
Avoiding WiFi or BT where it's not necessary sounds good to me.
Ok, I have OBD1 on my old truck.
I just made my own level converter/µC/USB converter.

If you can get USB OTG to work on your radio, that's the first step.
Then the question is: what USB UART standard is it following (copying).
Usually it's FTDI, PL2303, CP2102 or CDC.
In short, I can't tell.
I'm not sure which of these are supported directly by (which) Android.
But I'd like to know.
If you have one and plug it into a PC with Windows or Linux it's easy to see what it is.

Do you even have a FYT unit? You mention "I have the same unit". Same as who? the OP?
And below "with an Android radio".

Yes, it does work with a FYT but FYT has crippled Bluetooth and USB stack/drivers. There is a very specific stepwise approach to use: forget phone, make pin-code of unit the same as pincode for ELM dongle, couple the ELM dongle, then couple the phone again (if desired). And the BT identity of your OBD dongle must start with OBD otherwise you can't pair it at all as that OBD* is hard-coded in the crippled BT program/stack/drivers of FYT.
This has already been described in many posts/threads (too many to link to) for FYT units. Do not only ask here, but search the FYT subforum.
And if your unit is not a FYT, you are even in the wrong sub-forum.
