Hi Guys
Haven't been on here in a while, but I'm still around
Anyway, now that I've had the Colorado 300 since Feb 08 and use it a lot, have to say I'm very pleased overall with the unit. Did have some software bugs on it for a while, but Garmin's last few updates really sorted it out. A superb unit now in my opinion.
Rugged and dependable under all conditions so far for me. I also now use it on a KTM 525 enduro trail bike in sometimes very tough conditions without any problems.

Only negative thought would be that it has so many functions on it can take a while to fully master it, but when you do its great to use.
