I couldn't get any of the DYI for the V1 or Passport hardwire install to work on my 2011 335xi. I found a switched 12v source in the same lighting console on the 3rd connector from the drivers side or 3rd connector from the bluetooth microphone connector. Its a red wire with black stripe. about 18 AWG. I was able to use the same 10mm bolt for a ground. No power dropout with sunroof open. I will attempt to use the same source to power my dash cam's 12v to 5v voltage regulator.
