Backup camera

[bluecuda]

Having a issue with my backup camera during the day it works fine but after dark the screen on the radio goes white or blank. anyone know if it's the camera or the radio causing the issue? motorhome is a 2019 Gulfstream conquest 6220. Tried using a led light on the rear of coach and it made no difference. Any help would be appreciated.

the backup camera operates thru the radio in the dash that was installed by the gulfstream motorhome folks. questioned them before about the radio and they had no clue what type radio was installed in our coach.
