Hi, I picked up an Earthmate GPS and bought Route 66 "ROute USA and Canada software and was under the impression that it would work with most GPS drivers. This Gps unit is USB driven. It shows up in my Apple System Profiler but it is not being recognized within the software. It works on the PC with the De Lorme software, but I'd really like to run it on the Mac! ??? Do you have any suggestions on where or what drivers might be available to make this work??? Thanks, Dan Johnson imageman at optonline.net The company Adventure GPS that I bought the Route 66 software suggested that I buy a Pharos GPS unit but I want to see what I can do with this one first! Thanks Again!, Dan
