Absolutely true for me. It lags just long enough for me that I think it has dropped back to the phone. The screen in my Subaru changes from the caller's name/number, then "BT-1 paused" then goes blank, THEN back to the caller's name/number. It also mutes during this 3 second interrruption
It used to stay on caller's name/number with no muting.
For the last month, I've hit the "answer" button again, thinking it had dropped back to the phone, but it hadn't. But now I HAVE sent it back to the phone. NOW I think the call has dropped and my Bluetooth has lost connection. The caller is hearing my muffled swearing from the phone in my pants.
Only LAST NIGHT did I figure out this sequence of events, and that it is only a IOS 6 delay bug, and that if I wait it out, it is working "correctly"
I was ready to go do battle at the dealership for a solution, even if it meant a radio swap/upgrade, even though I was pretty sure it was another IOS 6 issue.
I am so glad this is not another one of those IOS 6 issues that "only I have"
I am also confident that this will NEVER BE FIXED by Apple.
