My unit is plauing some serious head hames with me. Now all of a sudden when i start my truck the rear kenwood cam comes on with no X to close. Then shows guidelines for a minute until i push a bunch of buttons on the front of the HU then the warning screen pops up.

Its acting like the kenwood cam isnt compatible. Im using the Pioneer camera for the front cam.

Anybody else using a kenwood cam with this HU?

Not sure why this double posted. Got the "Something went wrong" error when i first tried posting.

Maybe you have your radio set to trigger on the wrong input logic?  The radio has an option to enable the camera on either 12v or 0v. Maybe you should change to the other option or check your wiring.
