just had the f90bt installed last week, about 3 times now i've started the car and i get no audio. i can get it back by shutting off the car and the unit, powering back up, no prob. i tried the reset button while driving and that didnt fix it. im wondering if im the only one having this problem or not.
I am having the exact same problem. Sometimes when I start the car, no audio from any source. Turn the car off, open/close the door, start car again and everything works. Also, occassionally, my ipod audio only comes from the left side (no work around found for that yet). I have been told I may have a bad bus. Guess I need to find a shop.
let me know if that helps, mine did it again this morning. its gotten a little better but still does it about once a week. let me know what you end up replacing. thanks! rob
