Got a '13 X5 E70 with Techonology and Executive Package and realised that there is some sort of dashcam looking thing mounting on the back of the rearview mirror. Problem is, I can't get it to work. All my other cameras work (backup, front sides, under-mirror). Please shed some insight on this as I would really like to use all the cars capabilities
. There has to be a way for it to work as the camera is built there.
