I have my XM Onyx mounted to my handlebars. The kit came with a little metal square for the magnetic antenna that mounts with one of the 2 bolts that hold the clutch reservoir. I have a Kury socket power point that I plug the 5.5V power adapter into, and this is directly wired from a 6 circuit fuse block, off the battery, and I have a Miccus Bluetooth sender that plugs into the speaker jack on the back of the Onyx dock. The Bluetooth goes wireless to the SENA 5 setup inside my helmet. The audio coming through the un-amplified speakers is fine w/o being too loud up to hiway cruising speeds, then it gets hard with a little more wind noise to deal with. I have a Hondaline w/s not a fairing. DID NOT have to get into the headlight for my tunes.
