I just got my Montana 650. I'm a first time user of any GPS. I've loaded City Nav from the website as it was a newer version of my cd. A couple of questions; 1) does city nav also run on my pc? I know I got it loaded on my gps unit, but don't see how to run it on my pc if it allows you to. 2) basecamp. Where do I get this software? My unit has no informational instructions on how to do this with it in paper form, and I don't see anything on Garmin's site that answers my questions. Thanks for any input.
