I just want to let eveyone know that XM Radio works great with the Garmin audio in my SR20.
I have the Delphi portable XM receiver. This unit works with an optional “boom box” or an automotive adapter. I use the automotive adapter. Simply plug the power plug in to the accessory power receptacle (lighter) and then use a 3.5 mm male to male cable to connect the output of the Delphi unit to the Audio 1 input inside the center console.
The Delphi unit is so small (about 3"x4") that it fits nicely into the center console with lots of room to spare.
I really enjoy listening to “Atmospheres” while flying. As you know, the Audio 1 signal is soft muted whenever there is any radio or intercom activity. It’s really great.
Sorry if a post like this has been made in the past.
