Handsfree problems in car

[TheDemon]

Hi all,
I have bought a Kaiser last week which replaced my broken Trinity. The last OS run on the trinity was a Bepe 0.79 german rom.
Now after changing to the Kaiser I have some minor but very annoying problem with the bluetooth connection in my car. My car is an Audi A3 that is officially not compatible with WM 5 and 6 but was working great with the Bepe rom.

The problem occurs only if you turn on the engine during a phone call.
The behaviour is the following: If you have an active phone call and turn on the ignition switch the phone connects to the to the free speech unit in the car and you can continue with your call. But if you continue and turn on the engine the connection between phone and free speech unit gets lost.

Does anybody has an idea how to correct this? Perhaps it is just a registry key to change as this problem did not occur on the Trinity...

Thanks for you help

Welcome to a world of problems! There are a couple of threads on people having problems with built in car kits. I'm sure one of them was an Audi and the person never found a real solution, just a work around (that was a contacts, not a call issue tho.) I personally had some issues with my old HTC Uni running a cooked ROM (which was a vast improvement on the total failure I had with the standard ROM!), these just aren't present with the Kaiser. I guess it's just luck of the draw and something to do with the overall package as I have several issues with different bluetooth devices, some working well with old phones not with new, vice versa, some being buggy with all. Sorry to report bad news, but if you do find a solution that works for you, great!

Sorry...can you explain the problem again? I'm not following. If you have an active phone call and turn on the ignition can you or can you not continue your conversation? The two sentences seem to be saying opposite things.

I think what he's saying is that if he turns to the accessory position, or ignition position, depending on how many positions there are (probably the one where all the lights on the dash light up) he's fine, but as soon as he turns the key to actually start the car it goes wrong. I have a feeling this would be due to the momentary powerloss to everything but the starter circuit. Dunno if there is a way to fix that, apart from wiring the carkit to a feed that stays live all the time and isn't cut when the car is started.

Funny enough, I've got a similar problem on the bike. The radio has an external display/remote plugged in (Sony headunit, RM-XM10B display/remote) which lights up when the ignition is switched on, but due to the brief cut in power to the radio when the bike is started the display goes blank. Radio comes back on fine, like it does in any car, but the only way to get the remote display to work again is to cycle the radio off/on. That might just be the way the carkit handles a brief drop in power and the only way to fix it is to wire it directly off the battery. A good auto electrician should be able to wire it so that it gets a constant live direct from the battery, but switched via a relay that doesn't die when the car is started.
