One of my bosses invited me to lunch last week. Inside his vehicle, he had a built-in GPS navigation system. I'd never seen GPS in action until then, but wow...I was impressed. So, I've got the GPS itch and was wondering if anyone has tried any particular models or knows of somewhere to get some great information. I was taking a look at the Magellan product line (just the first to come up w/ Google) at http://www.magellangps.com/en/gpsAdventures/driving/
Ideally I'm looking for something w/ a touchscreen and the ability to download maps either to the built-in memory or to an SD card. North America only, primarily US roadways / highways.
Thoughts / comments? Thanks!
