Hey everyone! I've been looking into upgrading my '15 with the 130 radio to an aftermarket Pioneer. I've been speaking to some advisors on Crutchfield and the most recent one I talked to added this 80 dollar Sirius XM tuner to my cart...none of the other people I've talked to have mentioned anything about a tuner. My Jeep already has Sirius with a factory antenna and everything, but all of a sudden, now Crutchfield is telling me I need this tuner and I also need to run a new antenna. Just wondering if anyone has upgraded to a new radio but retained their Sirius without running new wires (seems pointless to me if there are already wires there for that purpose). I can understand if there are different connectors or something along that line, but I really don't want to buy all this extra equipment if I don't actually need it (it's going to be an expensive little project as is). Just wondering if anyone has any experience with this! Thanks in advance!
