I've owned the original Karoo since last August. Logging about 2,500 miles on it. I haven't had any of the problems that I've read about here and other threads. Frankly I think it's great. I'm not sure if I'd buy Karoo 2, since this unit does all I want it to. I use it on every ride and download into my Strava account at the end of the ride. I've created routes as well as downloaded the route for the canceled charity ride in Solvang, CA. I've uploaded my rides into Google earth as well. Maybe I got lucky, but it works, even in sub freezing temperatures that we experience in the fall and spring.
