Please forgive the rant: Why does Garmin's software suck so bad compared to Google Maps? Specifically, I use BaseCamp on the Mac, and I've also tried Road Trip. Google is leagues better in almost every comparison: address finding, panning and zooming... It freezes, it lags, it crashes...
I haven't figured out a way to plan a route using google maps and the Garmin exporter plug-in, but its pretty good for finding addresses.
I wouldn't have posted this, but I'm pretty frustrated. In Google I type "philadelphia to Greenville SC" and I get a bright blue line on a map and directions. In Garmin's software it is a total trial to plot this route and upload it to my gps.
