Garmin sells a motorcycle dock for that unit. Cost is around $70.00 an it includes the wiring harness you need to integrate the GPS into your radio. To get the full benefit of the spoken instructions you will need to purchase a HD Navigation Interface Module or NIM. The addition of the NIM makes the installation almost painless and allows the spoken GPS instructions to override whatever media you are listening to. Harley also sells a dock that mounts to the inner fairing, but it interferes with the installation of the three pocket windshield bag. Sorry I don't have any part numbers handy.
