Simple problem solving? Eliminate the variables and it's pretty clear where the problem is coming from. Nothing with the phone has changed since these problems started occurring. I pulled fuse 29 (which rebooted Sync) and voila the problem is gone! I drive somewhere, turn the car off, do my errands, return to the car (meanwhile, nothing has changed with the phone) and the problem is back. Tell me, do you really think you can attribute that issue to the phone (especially given that it's pretty well established at this point that this iteration Sync/MFT has a lot of bugs?)
I have an HTC Incredible, running Cyanogen 7 as well Since having this issue where fuse 29 helped and then the BT audio broke again I've repaired the phone and fiddled with settings on Sync/MFT to no avail. $100 says if I yanked fuse 29 again everything would work again (for 1 car ride at least...)
