I have had a xm radio in my coupe since I bought it 11 years ago and I love it. But recently I was in a rental car and found a new station for 1 hit wonders on channel 303. Well much to my surprise I can't get my tuner to go above channel 237. My wife's 2012 Acura has the same issue.
I figure this is likely due to older tuners without programing for these new channels. So now I am wondering if there is an option for me to get a new tuner that is integrated into the factory radio? I can use my OEM head unit and steering wheel controls, so I would like to keep it that way.
Here is a pic of the tuner I have.
