Hope someone can help. I replaced my complete faceplate and screen due to fluid ruining my last one.
All the buttons function on the new but no screen. I can see icons etc. With a flashlight.
No reverse camera. Park brake bypassed by grounding the wire. Performed a factory settings reset, no password, performed a system reset through the pin hole. No go. All worked fine this way before.
Can anyone provide a pin identification for the head unit?
I'm on a budget and hope to repair the unit I have.
