hey.. i have a 2000 323i and i just got a escort passport 8500 and it shows that the power is still on even after i shut the car. my other cars always shut off the cig adapter when i shut the car off so i found this strange. anyone know?
yes, the cig lighter stays on all the time. If you don't want to drain your battery, hardwire your radar detector to a switched power source so that it will automatically turn on when you start your car and turn off when you turn off your car.
Look where your sunroof controls are, and remove that panel. To your right, on the passenger side, there is a group of 3 taped up wires with a white connector. The blue/green wire is a 12v power source that goes off when you shut off the are.
