I have an 2010 Audi a6 Avant with Bluetooth Phone prep and MMI . I Phone 4 with IOS 5.1
I have had problems with the bluetooth connection. The MMI screen shows the phone is connected , but it has no signal. The phone will not sync with the car . This seems to happen when I first start the car but it is random and in frequent ( several tiems per month).
If I go into the MMI menu and try to disconnect through the audi bluetooth settings the MMI screen says bluetooth switched off but the screen still shows the phone symbol is connected.
The audi mmi system becomes un responsive and cannot disconnect ( when in the bluetooth setting area). Normally within the space of around 30 mins to an hour later the MMI system shuts itself down and re-boots . The Bluetooth then 95% of the time resolves itself and functions perfectly, until the next random time the MMI has locked up.
if you switch off the engine and then re-start within a short space of time the mmi does not recover.
If you leave the engine off for a few hours and then switch back on the MMI system the system almost always recovers.
The fault appears to be with the MMI system as it is becoming un responsive and re-boots itself after a period of Time . In addittion the MMI system does not seem to have the correct ability to drop its bluetooth connection when switching it off.
I have contacted Audi and they say its the phones fault and that its IOS 5.1 at blame.
I would like to understand if Apple are able to respond.to audi's accusations???
Unfortunately as the customer of both and Audi and an Apple , I am caught between 2 giants in Industry with neither party admitting ownership of the issue and letting the customer suffer the misfortune of one or both parties errors and in ability to own up to their issues!
would love to hear from other users in the same predicament.
Cheers
