I've had my 900BT for about 4 months and it worked perfect. All of sudden last week, the backup camera intermittently stopped coming on when putting the vehicle in reverse. I am able to choose the rear camera from the source screen and it works fine. Sometimes it when putting the vehicle in reverse, it will come on for a second or two and then pop back to the previous screen. Does anybody have any ideas? Now the unit will not fire up the backup camera unless I manually choose to do so. Otherwise, the unit is operating flawless.
