I am installing a Road Top MMI and a back up camera to my 2012 E93 (CIC). I am trying to avoid using the reverse lights for 12v and chassis for ground. What I am wondering is can I use the "12v Backup Camera" and "Ground" wires in MMI harness to power the backup camera instead? I'm positive that the 12v is providing 12 ACC but I'm not certain that ground wire is going to effectively ground the camera. That *appears* what it is for -- grounding a backup camera, 360 camera, and/or DVD player since there are unique video inputs for all three. I am also uncertain if I need both the "12v Backup Camera" and "Backup Detect" connected. I have the power to the camera connected to the "12v Backup Camera" *and* the red wire attached the video cable connected to the "Backup Connect" wire. Are they doing separate things? There is no documentation from Road Top on this and their tech support couldn't care less. I know this unit is very similar to the Andream unit which is quite popular on these forums but I've never seen anyone not use the reverse lights for power. Any advice would be appreciated.
