I have an 06 A8 with factory BlueTooth, paired to an iPhone 4 (GSM on AT&T if anyone cares). Occasionally, while on a call, the BlueTooth will just drop out, and the car's display will say "phone not connected properly" (or something of the sort, I'd have to go look next time for the exact message).

Some days, it will drop out 5 times on 7 calls, other days, it will work perfectly.

Needless to say, this is incredibly frustrating when it occurs.

Any thoughts people?

 

I have the same issue except my wife's iPhone connects and stays connected just fine while mine does not. I've had my iPhone replaced and that doesn't resolve it. Have you had any luck fixing this?
