Car Kit Bluetooth Performance

[hambola]

Whenever I sync my Touch Cruise in the car (BMW) the interface lags! For example pressing the phone button on the steering wheel takes forever to pull up the phone menu on the car display. Also during a call if I press the hang up button on the steering wheel, it doesn't hang up right away. I have to keep pressing it multiple times. The actual sound quality through the car speakers is fine and the pairing is very quick so no problems there.

Is this a specific problem between the car and the phone? The car handles other bluetooth phones very well, such as the ahem..iPhone. The response when hitting the steering wheel buttons is instantaneous.

I currently have udk Syrius R8 Beta2 with radio 1.59.46.12. I read in one of the other forums on xda that it has something to do with TouchFLO. I disabled the Manila TouchFLO, turned off S2U2, still no luck. Any ideas?

I have similar problems with my XDA Orbit2 with WM6.1 and with my Ignito/Diamond with WM6.1 both with my Peugeot car BT and with Motorola BT headset.

An incoming call sometimes takes 10secs for the audio to be re-routed, PITA

I also found that if I'm running Navigon 6 and an incoming call gets picked up by the car BT then Navigon (or any other GPS app like GPSCycleComputer) gets screwed, the internal GPS gets disconnected.

I'm suspicious that the problem is due to the on chip BT and GPS.

My XDA Orbit (1) with WM6.0 doesn't have the same problem but of course it also has a seperate SirfstarIII GPS.

So, who knows, it could be WM6.1 or it could be the Qualcomm integrated chipset?

I'd like to re-install the original Orbit2 WM6.0 to see if that makes a difference but that's not completely simple as there is no full (official) O2 WM6 file available (AFAIK)

Yeah it's pretty annoying. I assume the udk ROM that I have has all the bluetooth patches, etc. I know other phones don't have this issue, so I'm hesitant to say it's the BMW bluetooth firmware. Something is laggy about the device when paired. I must say though I've never tried pairing it to a BT headset so I wonder what that will be like.

No one else having bluetooth performance issues with their car's built in Bluetooth system?

I have carkit trouble, but don't know why.
My problem is as followed:

I Drive a Renault Scenic with a Carminat Navigation System including Bluetooth Carkit
When I connect my HTC TC Everybody complains that quality is poor. Reception is louzy etc.
When I connect my HTC TD2 the problem dowsn't exist.
When I connect my Samsung Omnia the problem doens't exist ( but other problems in the phone appear)
When I connect my Nokia N73 with the current software I have a lot of problems ( even other then with the HTC )
When I connect my Nokia N73 with an old version of the software I have no problems...

All phones run the stock ROMS ( Windows Mobile 6.1 Pro ) / original Software. I first thought It might be a carkit problem, but as some phones work and others don't I tent to believe that it is a ROM problem (Maybe radio not good)

Is it possible to update the bluetooth driver / firmware?

Problem with HTC TC could be in radio driver.
But since there are problems with other devices, it could be problem with Carminat. You should check with Renault is there software update for it.
But first check if those phones are on Carminat's compatibility list...

The strange thing is that I have the problem with the nokia N73 when the software of the phone is higher then 2.69

According to Renault all Windows Mobile devices are supported / compatible.

I think it is the BT driver or Firmware. But don't know if it is possible to upgrade this to a newer version. Or to test this?

Yes,


My Parrot Mki 9100 works perfectly for phone calls, but doesn't play GPS navigation audio instructions.

Anyone know waht is wrong?

Have an appointment at the car deakership on Tuesday to see if there is an update or quickfix...

I still suspect the TC though

[Bodisson]

BT, GPS and GSM are controlled by radio driver.
Please check version, since even stock ROMs use different drivers.

So far, my version is flawless...

hi,
I have have quite some problems with BT connection with same radio driver see

I sent it for fixing to the dealer.
Hope a solution.

Went to the car dealer today. They updated the software and modified the microphone volume (lowered it) and the sound quality is improved.

At the car dealer they told me that they have a lot of issues with HTC phones in combination with the different carkits, although the newer phones have less problems. There is a new software upcoming before the end of the year which should solve more problems. but for now the problem is less....

I figured out why (but not the underlying cause) of the sluggishness when the phone is paired to the car. My phone shows very high CPU usage (90%) with services.exe when I look in task manager when the phone is paired. I noticed that using the actual device is sluggish, even just typing up a text. I don't know why that is. The moment I turned off bluetooth, it was back to normal.

Any idea what could be causing that?

[Bodisson]

Maybe radio driver...
I had such problem when I was on WM 6.0, but it was caused by failing radio chip...
