I have a Kenwood touch screen head unit I'll be installing in my 2015 JK. I first had it in my C6 Corvette and then moved it to my Chevy 2500. In both Chevy's I was able to tap into the factory satellite antennas instead of installing a separate antenna. My Jeep with the 130 radio has sat radio functionality, so I know there is an antenna and tuner somewhere. Anyone know where it is and how difficult it is to get to?
