Call Garmin? I did, only to find out they anticipated at least 20 minutes waiting time! I am not that patient, I guess, and it's not Toll Free outside the US... So I eMailed them, but still haven´t heard anything. I hope I end up just as enthousiastic about them as you are, but some things has to happen before we´re even close... I think I will call them next week, and hope things will work out, because without the backlight, it's pretty close to useless, I'd say.
Google Earth: I had a window seat flying from Houston to Chicago, and the GPS had no problem whatsoever acquiring 5 or more satellites. The sky was clear, so I had good vision on roads, lakes and cities, and the GPS (with USA base map loaded) was telling me which ones I saw and which ones were coming. So cool! Back home, I used the Mapsource program to send the GPS track from GPS to PC, and there's a Menu item that launches Google Earth (if installed) and shows the tracks!
