An Inmate here has a Garmin Colorado for sale. Mint condition, I believe a fair $250 price (Model 300 but has added Maps of USA "100" + a few more specific "24" Maps of the West, in essence making it a Model 400). It has a "jog" dial vs. buttons and/or a touch screen. I believe it runs only on batteries vs. a usb power port. Any other potential negatives that I should know about??? I think I can live with the two noted above. In fact, do NOT want a touch screen at all. Almost positive I would buy a 60 or a 62 series before a Montana, Oregon, etc. Just not a HUGE fan of the touch screen on my Android "Smartphone" --- especially when it's wet, cold, and nasty out --- and that's when I want an need my GPS to work WITH me, NOT against me... Open to ANY-AND-ALL thoughts and/or questions. Thanks! "COorbust"
