Hi. I’m installing this in a 2017 Challenger that does not have XM, and doing the head unit upgrade. The antenna has two lines coming out of it. Anyone know if they BOTH need to be hooked up? If one is XM what does the other line do? Thanks

Hi Paul,
If you can, I'd check with your FCA dealership and ask them if they can get you a wiring schematic for the antenna. I did find these schematics. I hope this helps.

Thanks. Won’t pull up on my phone. I’ll try my computer. I did get the UAQinstalled byBest Buy but I do not believe correctly. The nav will not connect and thinks I’m in TX even thoughI am in IN. The person who sold me the radio says that these 2 leads coming off the antenna, must be combined and plugged into the mustard yellow port in the radio. I can’t find a cord that will do this. He says I should have gotten the antenna with one line only.
