I have a 2015 JK unlimited with Navigation/ bluetooth/ steering wheel controls and XM radio. My wife wants apple car play so I bought her a Pioneer DMH-160BT and I also got a Metra Chrysler wiring harness (WM-CH13-SWC) that seems to connect fine to the stereo? Once I got the stock radio out of the jeep, the main problem(s) that I am having are the antenna for Sirius XM radio and FM radio are nowhere close to being the same as the radio. I have done the research for the antenna adapters and I think I need this one (metra 40-EU10) for the FM radio but I can't seem to find one for Sirius XM that would possibly go into the stereo wiring harness. The XM wire that connects to the new radio is like a round serial cable. Am I missing something?
