Happy Holiday's and congratulations on your new Bimmer! I just picked mine up tonight (2017 440 MSport convertible, Mineral Grey/Oyster Leather) and one of the techs was to install my V1, but the flat cord was too short so I've got to order a new one. We had a conversation regarding where he was going to tap for power which would be activated by the start button. I asked about tapping into the mirror, but since I've got the camera features he indicated it could be risky and would tap into somewhere else. In my previous vehicle (2014 435) the audio shop I used couldn't figure the install out and I had to turn it on and off every time which sucked, but I just didn't take the time to go back and let them try again. When I have mine completed by the service tech, I will ask for specifics and share it with you if you still need the solution. I will order a longer cord tonight and return it to BMW Service next week.
