I am a big fan of Sirius XM, in the house and both SUVs. Problem was our 2007 RT210 does not have a Sirious XM radio installed.
A few months ago Sirius XM came out with Sirius XM out of the car to subscribers for free.
We have a surround system that came factory installed in our 210 so I did some experimenting.
I have the out of the car app installed on my smartphone, i took the RCA input jack from the surround sound system and plugged it into the
Audio/earphone jack on the smartphone, pulled up the Sirius XM app, tuned to one of our favorite stations
and now we have Sirius XM radio in the RV at no extra cost.
I just keep the smartphone plugged into the 12vdc
Outlet to keep it fully charged while driving down the road.
Driving down the road in the RT210 just became even more enjoyable.
