I have a GXM31 satellite antenna plugged into a 545S GPS with the "Mariner Package" from Garmin. The XM signal has 2 RCA type outputs that go into the aux input of my receiver and the wether radar/alerts are fed into the 545. The XM is controlled through the 545 also, works great for me. I purchased them about 6 years ago.
