Alright. Here's the deal. My fiance and I are going on a roadtrip this august out west. I figured I'd get the Route 66 Mac software to have tons of maps and available directions available to me on my 15" Powerbook. I also need a GPS unit. I'm thinking of the Garmin 60c. or 60cs. What I'm asking you guys for is your impressions of: The Route 66 software. The Garmin 60c vs. 60cs- user experiences, etc... Also, WILL I be able to hook the Garmin up to the powerbook and just use it as a basic receiver with the Route 66 software for realtime directions. (I know I can't use the Garmin and the Powerbook together for downloading maps or sharing info, but I thought you COULD use it as a receiver unit.) I'm basically looking to see if anyone else here has any experiene with GPS and mapping software and if anyone can give me any tips. If you haven't used it with a Powerbook, that's okay. This will be my first GPS unit and I've grown to know and trust the opinions and information given on this site, so I'm hoping there are some GPS users out there that can recommend some GPS models to me. Thanks.
