Has anyone experienced Bluetooth failure? I have a 2010 with THX, this past Sunday I noticed my phone failed to connect like it usually does and when attempted to connect it, I receive an on screen message of "Bluetooth is off, would you like to turn it on?" I've tried responding yes to that message, turning it on through the advanced settings menu, turning the car off and restarting it and doing everything again to no avail. I'm concerned the Bluetooth unit has failed and was wondering if anyone else had dealt with replacing it.
