So i just spent about an hour searching the forums and it seems that people like the Garmin GPSMAP 76cx. I am interested in getting a gps system and had some questions:

My tour is half in the US and half in europe. This means i need to buy two different sets of map software from Garmin right?

I wont have computer access after I get to europe and am avoiding an itinerary so I would need the gps to make the maps for me. is this a good idea? does it work well?

anything else a GPS newbie needs to know?

thanks
