I have removed the mushroom. Remove the windshield. You need to remove both speaker covers and then both speakers. Remove both side panels careful not to brake the tabs. Remove the windshield metal lifting bracket by removing the clips from the four pins and pushing them out, top arms are spring loaded remove those pins first. Remove both front painted panels there is a push rivet you need to pop out and a screw behind the speaker and three on the sides. Remove the center section that has the mushroom on it. The mushroom can be unplugged from under this center panel and removing one screw under this panel frees the mushroom for removal. I unplugged the xm antenna connection from the radio and added a antenna I purchased on Amazon to the tail section of my bike. Mounted a GPS Garmin Zumo XT with a mount from FMS where the mushroom was. XM reception greatly improved and prefect place for the gps.
