had z110bt installed today on my truck . i had 90bt installed previously. reverse camera never worked properly. i was told the reverse camera didnt work with that model that well. so this was one of the main reasons i upgraded.

camera doesnt work when in reverse with the settings...camera on and polarity- battery.

when i change polarity to ground , all i see the the camera all the time.

I went back to the installer. he said it is the vehicle issue and suggested creating a relay.

any suggestions?

thanks

Your installer is full of crap. Take it back and tell them to get it right or refund your install charges so you can go somewhere else. Backup cams are very easy to install and they work will all units.

the only problem is that this installer just replaced the the radio . the wiring was done by previous installer who installed 90 bt.

Regardless, camera problems have nothing to do with the head unit or the vehicle. It is strictly install related. Any installer worth his weight should be able to install a backup camera with his eyes closed.
