Maybe I can help. First to set it up you need the three navigation CDs that came with it. Take disk number one and turn on the bike to accessory while it's parked outside with a clear view of the sky. With it set to radio mode (Am/Fm/Xm doesn't matter) insert the nav disk 1 into the player and watch the screen. It should say that's navigation is being activated. After a few minutes it will prompt you to press OK to accept the warning about not using it while driving. That's all it takes. It's now setup. If it has problems finding the satelites, you may have to take it for a slow ride around the block until it figures out where it is.
Once it's setup remember that you need the disk in to enter a location and find a route. Once the route is calculated the directions say you can take it out during the ride... BULLCHIT. You need it in if you miss a turn, or want to use the find Gas, Food, Lodging etc. feature. Sense switching disks while you're lost and just missed a turn sucks you're better off just leaving the dang thing in there for the whole ride.
Hope that helps!
Ride Safe,
