why not the colorado? in GPS Posted October 19, 2009 Another Colorado fan here. I bought mine around June last year and initially had some drift issues, which seem to have been sorted with firmware updates. I'm particularly liking HotFix for quick startups. Coming from a 76CSx (which I still have) I do find the user interface to be a bit clunky by comparison, and entering text using the R&R wheel is very slow compared to using the arrows on the 76. But it's a good robust unit (I've never dropped it in water) and I LOVE the paperless caching.
