Hello everyone. Gonna get straight to it...I have a 2016 RAV4, awd, no navigation, key start, non-jbl. I got a free android 8.0, 9" or 10" screen radio head unit from my brother, who works at Toyota. He pulled it off a rav-4 trade in and since it was an aftermarket product, they're not allowed to put a Toyota back on the Toyota lot with an after market radio and have it sold like that (for obvious reasons). It was either take it home or trash it and he remembered I had one. Only problem was the car was a 2018, but it should still work . I think he forgot some other harnesses and just grabbed the main one thinking everything else came with the car Anyhow, I installed it and everything worked, except for the factory back-up camera. Ask the settings, saves properly. I have the amp stepdown harness (AXCAM-6V) and I have THE RVC harness (AXBUCH-T3). Reverse camera still isn't working. Here is a better and more detailed explanation that shows all the harnesses I have and shows the back of the radio. Someone pls help. T.I.A!!
