Hmm. To be honest, I know absolutelty nothing about the state of GPS & Mac environments. What are the current GPS options for the Mac? Can GE / RoadNav integrate with any GPS receivers now? It seems for GE you have to have the pro version or whatever to do that? I think this
http://www.mp3car.com/vbulletin/maccar/71801-new-mac-gps-google-earth-program.html gets around that? I'll have to play with all that and see what's going on.
I'm sure I can do something like what you are talking about, but I don't want to say any specific time I'll try to get that done. I need to learn a lot about it first, and get myself a GPS unit. Can anyone reccemend one?
