Well, I am new to this forum and like what I see so far. I have the GPS unit in my radio and have to agree with some other comments that they could have done more (like a map). However, I have several other units and after using this one I will tell you that I think they didn't put a map on there to keep us from killing ourselves! Unless it is mounted higher, you wouldn't want to be looking down at a map.
It comes with two CD's that have the street level details on them and once you load a route you can take it out and listen to tunes. The problem I have with it is that when you are not using a "Route" it gives you NO information. All my other GPS units will at least show you the next street coming up so you can look for a turn or something. This one is either in the "Route" mode or just the "Stare at you mode". I got a 25% discount on it and having it installed at the time of the bike extended the warranty out to two years so I don't feel really bad. I am curious how much the updated data disks will cost once these are out of date. Sorry for rambling on....Cheers and Ride Safe (or the other way around!)
