[QUOTE="zippinbye, post: 8540441, member: 623244"] Messing with my girl's AVH-X2500BT last night resulted in greater problems. Originally went into it to resolve lack of back-up camera when reverse was selected. I noticed one back-up lamp was out, so I assumed a correlation. Not so, it was simply not selected "on" in the menu. After re-selecting the b/u cam function and replacing a burned-out bulb on the car, I had a major problem.

So all dad did was reselect "back-up camera on," and that function was restored. Now that's all that works. Now, on initial power-up attempts via turning ignition to ACC or ON flashes the primary screen with "OFF" displays for about half a second, before showing a dark screen stating "CAUTION camera images may be reversed" which I live always has existed as a warning in case the polarity is backwards, either in reality or as selected in set-up.
