Gamalot Posted November 16, 2016 Share Posted November 16, 2016 I have a 2015 RX350 with navigation and premium audio with XM. The car has an XM antenna and I need to know where it terminates into the radio or amp. I have a nice stand alone XM head unit I drag between vehicles and home and a lifetime paid subscription and would prefer to use the existing XM Shark fin on the car if I can find the end and plug it up to my head unit.
