Trying to hardwire radar, am I doing something wrong?
2021 M550i, I plugged red into red and black into brown, yet my radar does not turn on when I plug it in. Am I supposed to be plugging into the magenta wire harness or only the black one? I shined a flashlight at my mirror to confirm it has auto dimming function.
Thanks |
