I have tried "Route Buddy" on my 60csx and had problems, I would wait till they come out with a upgrade and maybe try it again. Current version is 1.1.1. I tried that before I put Paralells on my intel Macbook and it run's all my windoz programs perfect (you will need your own XP disc). For $79 it was the best way to get around the lack of Mac support from Garmin and still be able to use all the stuff I had bought back when I used a PC.(Mapsourse,CN 7, N Route) The GPS related stuff is the only thing I needed to run on my Mac and Paralells lets me do that.
