Had a blackvue 500 dash camera wired to the open sunroof wire pig tail in the microphone port. After service I noticed the camera unplugged. I plugged back in and I saw I had no power. Tesla says they unplug all dash cameras when they come in for service. First thought it had died and ordered a newer model. plugged that in and nothing. used the 12 volt power cable that came with new unit and it worked. checked my old camera with the 12 volt wire and that worked. Contacted Tesla and they said to bring the car back. I did, they said they could not check any system on car while non factory hook up was connected. un plugged wires from sunroof pigtail. Tesla checked fuse and it was good per Tesla. I dont have a sunroof, thats why the port is open and ready. Cant check the sunroof fuse as its a Tesla only check as its not accessible. Its in the Third fuse box tucked away in the frunk behind support brackets. Anyway, once I got home I rewired and had brief power and then nothing. This set up worked for two years with no problem providing constant power 24 7 to the unit. any suggestions why this now will not work? I will be going back to Tesla for an answer, thought I would ask prior to going back a third time.
