Re: where to install Car camera for my new F30
Careful of which workshop you get to do these for you. Newer BMs sometimes have issue with a higher power drain message if power for the camera is tapped in the wrong location. My brother had this problem on his F30, fortunately resolved by a nice mech at Mods Ministry (forgot to get his name...).
Interestingly, they also installed a constant power module for him, which cuts off the power complete if the battery voltage drops below a certain value, so even if the car is not started for long periods of time, the battery doesn't go flat.
