If you know somebody with a 62s, that is dumd enough to let you put your grubby fingers on it (sorry about the cheap shot, I could not resist), you could copy the files from that gps to the formatted one.
Hahahahaha that was a low shot :) Anyways it appears I didnt format the SDcard but the unit itself.... doh...... So I'm not sure how to get around this, I just want to put somemap on it so I dont hand him back a blank map. Is there any free basemaps out there?
