My Backup and side view camera system was working fine, now I get nothing, no picture from any camera, no audio from rear cAMERA EITHER.    Is there a way to test to see if it is getting power?   Where is the fuse?

Not sure if I'm having the same issue. Camera was working fine and now nothing,

all I'm getting is flickering lights at the control buttons but no pictures. Funny thing

is my steps stopped working at the same time 3/4 of the way retracted.
