XM came with my truck, with the 3 month subscription. Does the xm receiver in the car already use an ip-bus cable to connect to the oem headunit? So that I can just plug that ip-bus cable from the factory xm tuner into the brain of my avic-n2.
Or I see there is an XM data cable input right on the avic-n2 headunit, I assume the factory headunit uses the same input?
