I just bought the 2018 c-hr and trying to get XM radio on it. they have there aha that is not good. I connected my phone and can play my MP3's and the XM app, it does display the song but cant change channels or forward/back. Installed the onyx radio with the aux cable and c-hr radio shows aux connected.
I did see some people are changing out the head unit, pioneer makes the unit.
let me know if anyone has figured this out.
thanks
