TyTN bluetooth car kit issues

Hi everybody,
I completed some tests using my bluetooth car kit (Audi integrated BT MMI car kit). Here is what I saw :
With the original french ROM (1.18.256.2)
Outgoing calls
90% of the calls were interrupted during dialing or connection. The main problem was UMTS stability with the french mobile operator named SFR. After deactivating UMTS/3G and falling back to GSM, 80% of the calls were interrupted during the first minute of communication because of BT unstability.
Incoming calls
Impossible to take a call : half were immediatly interrupted, half were answered using the internal micro instead of the BT one.
With the JasJam ROM (1.20.305.3)
Outgoing calls
After deactivating UMTS/3G support all the calls are stable. Every thing is working fine and the Audi BT car kit works just fine !
Incoming calls
Still impossible to take a call : quite all are not well handled. BT is still unusable to take calls.
I don't think the BT car kit is the problem, because I am using it every day with a Qtek 8310 (Tornado) and both incoming and outgoing calls are well handled.
If you've got some experience, please share it. I am so disapointed that this marvelous TyTN cannot replace my Tornado, only because this "merdique" (<------ french romantic word ) bluetooth functionnality is not working ! :evil:

Hi Arnaud,
I too have problems - see:

Im also having problems with carkit.
Jasjam and kjam just dont connect with my carkit (while they pair with it) but Jasjam and all nokia / samsung phones work perfectly well with it. Even Palm treo 650 works.
Is this a problem with iMate sets or with Windows Mobile 5.0?

I've had a friend who also has a TyTN which we tried in my kit and it didn't work. It seems that users with other variants (e.g. Orange) don't have this issue?
Further (non-technical) tests have shown that if you answer or make a call, you can get the audio by going into the call menu and choosing "Turn handsfree off". My uneducated guess here is that there is some issue with the headset feature on the TyTN and by doing this, it resets the headset profile and bingo!
It is a pain in the ar$e doing this for inbound calls, but for outbound it is manageable - you simply dial the number and whilst it is connecting, do the menu->Turn handsfree off workaround. Hopefully the new ROM will fix it - when it arrives!!

Hi All,
Just to put in my experience.
I have an Audi A4 with a Gen II car kit. As there is no handset holder for the TyTn I am using the Bluetooth function.
I have the Orange SPV M3100 variant, which works absolutley fine with the Audi Bluetooth, with one problem....
As I don't yet have a car charger, when the phone goes into sleep mode, it appears to disable bluetooh (I occasionally get a 'BT OFF' signal on the car display). Switching off bluetooth, then switching on again on the phone tends to kick it back into life where it stays live for another ten minutes or so until the phone dozes off again..
I have heard of a few people who have also diagnosed the problem as possbily the phone going to sleep to conserve battery, and solved the problem with an in car charger. I will report back when I have a charger.
Again, I do not suspect the Audi car kit as I have previoulsy used this (on Bluetooth) with a Nokia 6230 and MDA Vario, with no problems at all (the Vario was externally powered from the car).
Maybe you TyTn owners can flash to the Orange ROM ;-)

Same Scenario Different Cast
I have a Lexus GS with BT.... here's my Undesired results
actually, the only Problem i am having is very annoying.
If i receive or make a call after i pair with the Car kit, EVERY Thing is fine,
The sound quality is good, the response time is good (no Delay).
BUT after that call is ended, the BT itself on the jasjam TURNS off...
so i have to turn the BT on After EVERY Single Call (either made or received)
Is this Normal, I don't think so, but i had to ask
I have the Original Ship ROM Arabic version

My BMW handsfree works just fine with my TyTN. No issues other than an occasional BT off (loss of pairing). Interestingly, it's not sleep mode related since it usually works just fine in that mode. Generally, disabling Bt then re-enabling it re-establishes the connection then all is well. I have no issues making or receiving calls.
No doubt CarKit issues will be addressed when HTC releases their ROM update. Recent information tells me that this update is pretty much guaranteed to be an AKU3.0 variant. There's a tremendous amount of BT stack improvements in this AKU that should improve this as well as A2DP bluetooth issues.

.. No issues other than an occasional BT off (loss of pairing). ..
Interesting! I have the same issue with MTeoR.. I wonder if MteoR and TyTn are based on the same HTC device PLATFORM.

Updated my Parrot CK3100 to the newest version and things still don't work too well. When I start a call on the Parrot it takes around 20 seconds to start dialing on the phone, and when I receive a call I have to pick it up, place it on hold, and retrieve from hold to be able to hear the other side.
I wonder what/why they changed in the Bluetooth stack, it worked perfectly on my Wizard...

Renault Laguna II integrated BT kit
Works OK with my Laguna system except for the signal strength indicator. It appears that this information is not sent or translated onto the screen in the car.... Calls are fine though, and I noticed that the car rings immediately, the moment the phone does. Could be because the TyTN has the "turbo lag" explained in another thread tho
Cheers

Try installing Jetware mobile extender, that adds signal and battery bars as well as network name.

I enabled Remote SIM Acces in the Bluetooth Menu and now my contacts sync on my Audi Bluetooth Car kit with WM 6.1.

Xperia X1 with DS-980 Headset !! Massive BT Problems !!

Hi,
When I bought the phone in November it had serious problems with bluetooth, it was turning on off and disconnected the headset during or especially after phone calls.
That is absolutley not ok and I am using SE's top of their line headset: DS-980
These massive problems with BT exist also after firmware upgrade to R2A - The phone handling seems smoother than before, there are little improvements like a battery symbol on the top bar, another BT symbol, but it seems that some bluetooth problems still exist.
Just minutes ago, the phone disconnected from GSM/GPRS/UMTS line and connected again while I was using headset and was listening to music through WM player - then the phone suddenly restarted !!
I think that this is not the problem with the compatibility of this headset only, I did not try others but I think it will make same troubles with them too.
BT BUG in detail:
* Connect / Disconnect Phone when using headset intensive
* Headset (DS-980) especially disconnects after phone calls
* BT icon dissapears sometimes -> then it has to be switched off and on again to work "properly"...
SO MY QUESTION: CAN SOMEONE CONFIRM THESE BUGS/PROBLEMS ?? Is it the headset or a bug in phone (hardware or firmware ?? )
Thanks,
Freako

I have almost the same problem with my Volvo XC70's built-in hands-free - phone randomly disconnects from car in standby mode as well as during phone calls. I found some solution but haven't tried it yet - there is a program which stays in memory and checking BT status - if it's OFF the program restarts it.

i´ve the BT Headset Ds980 too but not such problems...
but beforce the update i had problems with calls...i couldn´t answer them with the headset...if i accepted them with the headset, i had to use the phone... the device did not stream the voice to the headset but now every thing runs "perfect"^^

Bluetooth and S9 issues on 2.73 ROM

Hi
I have the T-Mobile G2 Touch and a Motorola S9 headphones. Using the Origianl Stock T-Mobile ROM i have had no issues with bluetooth.
BUT
using the generic 2.73 ROM i have issues with connecting to the headset
It will connect, then instantly disconnect, then try to connect again, at which point it fails to connect properly
To Reproduce:
Using a HTC Hero & 2.73 ROM
Pair your S9's with the Hero
then Turn off the S9's and Bluetooth
Then turn on Bluetooth, and the S9's with the Bluetooth Settings up
you will see it say "Connected with Media", "Paired but not Connected", then "Connecting......." at which point it will fail
I have tried all the different radio versions to make sure it isnt a issue with the radio, but the same problem prevails.
Does anyone have any ideas on how to fix this issue? or what is causing it?

I also had issues with an unlocked Hero and a Sennheiser MM200 headset. Worked perfectly on original rom, but very fiddly to setup with the 2.73 rom.
The only way I can get them to work properly with the phone is to:
1) Make sure headset is turned off, as well as bluetooth on phone
2) Turn on headset
3) Then turn on bluetooth on phone
Headset connects as normal - any other sequence doesn't work.

I have tried this, and it doesnt seem to work. I have been trying it for the last hour.
While in Bluetooth Settings it says its connected with media, then is disconnects, then it trys to connect again, and then it just says "Connecting.........." for ages
The Headset light flashes as if it was connected.

I also had problems connecting MM200. I could connect it, but then it kinda stuck when i was pressing play button.
But then i decided to check my old sony ericsson bluetooth headset - it was working normally. And after that the MM200 also was working. One wonders.
Still i've noticed some stuttering problems when song starts. And it seems to start with faster tempo and then slow down after 10 seconds to normal speed (could be related to that stuttering? Trying to compensate for the lost time or something). No issues when i'm listening to wired headphones - so it must either something with hero bluetooth or MM200.
I have to check how it works with my old headset, but i'm kinda afraid of having MM200 connection problems again.

Ok
i will keep playing around. i have some CX-300II coming next week so i have a backup plan if i cant get the bluetooth stuff working properly
Thanks for your help

I think the speeding up / slowing down and stuttering is more to do with the Hero - I have tried the headset connected to a laptop and there is no problem whatsoever. Hopefully the next Android update will improve the bluetooth problems.

not compatible with new mazda 3
Well the hero is probably the best phone ive had and ive had many many phones over the years including the jesus phone which was pants.
Well ive just bought a new mazda 3 and unfortunately the hero does not like connecting to the car via bluetooth. tried all sorts. sometimes it works but usually only for a couple of times and then manages to lock the car radio up.
So its bye bye hero for me as i need a compatable phone for my car. looks like its back to nokia...shame as i really love the phone

Connecting to my BT car

Hi,
I have a Touch 2 and I am having troubles conneting it to my Volvo BT carkit.
With my S730 evrything worked fine.
Now the phone paires with the car and syncs the adressbook, but when I initiate a call from the car or the phone, the carkit just doesnt know he is in a call and does not mute the radio. I don't hear any sound through the speakers at all, but the phone thinks it is connected to the carkit and is in handsfree. Pretty anoying as you can imagine.
I upgraded the car's BT stack to the latest version 04.23_R but with no result. Disabling the data connection worked for some people but not for me.
Do you guy's have any registry hacks or procedures I could try?
The old phone worked great so there at least should be some backwards compatibility.
Thanks,
Jan

Bluetooth carkit (audi factory)

I'm having much fun with my new Legend, and I love android 2.1!
Everythings goes smooth except the connection with my car.
I have a pretty new Audi TT from 2008, and with my old phone (t-mobile G1), I used it without a problem for over a year.
One month ago I bought the Legend, and bluetooth connection to the car seems to hang!, Even when I disable bluetooth, the phone becomes slow, and the bluetooth icoon keeps displaying in my notification erea.
One thing works, when I reset the phone, I can use the carkit for about 10 minutes, then it starts to disconnect. The adress book never syncs.
Can people please reply if they got their legend work properly with their bluetooth car kit.
Also when other people have problems, please reply here!
Thnx

I have a mini cooper S with BT car kit.
The connection is good and all the contats are correctly transferred but sometimes the connection has been lost.
It seems it happens during the net switch (between UMTS/GSM).

Same problem here. Kenwood DDX7029 with BT. 5 out of 10 times the phone won't connect when starting the car. Dis- and enabling BT does the trick.

This implies that if you disable data-roaming, it would work all the time?, I'm gonna try that out! Thanks for your reply!

Hi there. My first post in XDA
So cool that I found this thread because I have the exact same problem. I have an Audi A3 and the bluetooth connection is 9 out of 10 times lost during conversations and then the bluetooth icon just hangs until I boot the phone.
I'm gonna try to disable the data-roaming and see whether it works.

Still problem carkit/bluetooth Legend!!
Hi all,
I still/also experience problems with my Audi A4 carkit.
Also my colleague with a Opel Insignia experiencing the same problems.
I have to reset the bluetooth or reboot the phone te fix it
It is very annoying when you loose the bluetooth connection within a call.
I have already sent a message to HTC...and still waiting!
Switching off the data roaming or fix the UMTS/GSM settings doesn't help
Somebody a sollution?

Audi UHV 6654 problems
I have a BIG problem with this car kit connection...BIG means the device is useless till now.
I've paired the Legend with my A4 factory car kit and there are several problems:
1. No sounds come from the speakers (car speakers), still the michrophone is working fine. I had to put the phone on loudspeaker to hear something but of course this is not the normal way of using a car kit
2. There is no sound till the call is actually ongoing (the other party respond)...that means no ringing, busy tone, or whatsoever sound... I don't even know if the call is made if I'm not looking to the phone (and if it's entering power saving mode, I stare at a blank screen).
I don't have any problems of this kind using a Nokia phone and also they (especially point 2) are happening with all smartphones I've tried (WinMo or Android ones).
Is there any software (even a paid one) to outcome this?
Please don't tell me to "try" this and that, I don't want to spend money "trying" things...I would appreciate if someone had a similar problem and managed to solve it somehow.
P.S The phone is brand new (got it for 2 days by now) and it is not rooted.
P.S.2 The car kit is a "basic" one, don't have navigation, contacts downloading and all that stuff...It's a plain BT car kit, I would just like to be able to make and receive phone calls with it.

Seems like many have bad experience in making the legend and car kit work together.
As of yet I could only pair my legend with my blaupunkt audio system, but they have not yet connected each other successfully to make use of the bluetooth feature. I've had no problem at all using my audio set with my samsung galaxy spica's bluetooth. So it probably is not an android issue.
Is there anyone who didn't experience any such trouble with their legend and car audio system's bluetooth ?

To add some more details...
I search for BT devices, phone finds the Audi UHV car kit. Then I'm asked for the pairing password and I enter it, than I get that "connection sound" from the car speakers but the phone is still "connecting..." endlessly. The BT icon on the phone appears but is the standard one, no headset or car kit icon appears (does it have such an icon after all?)
From here...nothing special happens. When I make or receive a call only the phone is ringing, no sounds came from the car speakers. Only when the call is connected, then I have the bord computer showing "Call..." and the radio/CD is muted...and that's all. The conversation can be heard only into the phone not from car speakers as it was the case with the ringing tone before. When call ends, music resumes.
