**Update** After three hours at the dealership and $300, the tech found a bent pin on the antenna connection. Were it not for that, I’m pretty sure my upgrade would’ve been plug and play. Everything (climate control, phone, nav, XM/FM/AM) now works on the new-to-me radio.
The $300 is what I was quoted just to flash the new trailer brake controller, I added while replacing the radio, to the truck. Guess I got 2 1/2 hours of diagnosis/labor for free.
Original reply:
I think they’re interchangeable but maybe someone with more knowledge will chime in.
I replaced the 5” in my 2015 1500 Tradesman this morning with an 8.4” from a 2017 Cherokee. I have everything working except XM and nav. Error message on XM screen is “Check antenna. See dealer for service.” I’m hoping I just didn’t quite get the antenna plugged into the back of the new radio.
