The system info and model number are shown in the first video. To recap the questions shown in the video:
(1) My reversing camera was working fine when I received it but I think I messed up a setting somewhere because now it's just black. I show all the cables and settings in the video.
(2) No sound from rear speakers.
(3) By chance is there a way to disable the side mirror tilt when reversing? I don't have the original headunit.
(4) Are there any of the unused cables shown in the video that need to be hooked up somewhere?
Thanks for any help!
