I added a backup camera recently. Multimeter shows connection to backup light has power. Plugged into Rearview camera in on the head unit.
Problem: won't show the rear view when car is in reverse. After much searching, I found a box in the online manual that says to go into the settings and turn camera view on.
When I try that, the settings button is gray. Only the AV and Audio buttons are colored.
What do I do to get the settings button active?
Thanks.
