I am looking for a way to connect my XM Roady-2 to my BMW factory radio on my 2005 r1200rt. I was told that I could use a patch cord from the BMW auto dealer (part # 82110149389). The patch cord is to connect into the auxillary port on the oem receiver, then to the sattlelite radio receiver. Is anyone familar with this & feedback is appreciated... To update on this post since installing the patch cord to the radio (with some help when contacting BMW parts reps. at Chicago BMW & Southeastern Michigan BMW). Still need to test the patch cord with the XM radio, I don't know if there is going to be enough amplifier to raise volume to a when "going down the road" audible volume. Will have to do more testing.
