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.

Parking brake.

Explain a little more please.

Parking brake must be set to access some of the settings. If it is set and it is still grayed-out then your unit is not properly installed (parking brake wire is not connected or not bypassed).

That worked, thanks.
