Hey all, I have a 2017 740i that i just bought a few days ago, im trying to see if there is an easy way to install my V1 detector. I havent opened anything up or tried to install it yet, Im looking for advise on getting the job done the best and easiest way.. I understand the easiest way would be to plug it into the cig lighter. lol. but i dont want everything hidden and ran up above the mirror. Im unsure it all the wiring for the headliner controls is all low voltage or not. has anyone done this?
