Default Re: Sync 3.4 issue

Update, I have had the car to the dealer, they re-flashed Sync 3.4, same version number, and also changed the door speaker. They did comment a known problem resulting in loss of sound across vehicle. I was told to switch off the car, lock the doors, wait 5 minutes, the unlock. Apparently this resets the car. And when it happened last time, i had the reverse tone go "squeaky", a very different tone. At this point all good, see how we go..
