After messing with the video cable, now I'm getting the front view but now stuck only on the front view
Cant toggle with switch to change to back view or default screen

What is the problem?
Is it the switch or the cabling?

 

Probably your cable.
Call the company. I talked to the owner on the phone and he helped me troubleshoot while everything was laid out (deck uninstalled in the dash). Was my cable.
He sent me a replacement cable harness and I was on my way

Sorry - my issue was the relay wiring
