Thanks, everybody.
Growley, I have a couple of more questions for you. I have a Dell TrueMobile 1180 WLAN CompactFlash Card (2.4 GHz), will that do the trick? (Sorry, if it seems like a dumb question, my husband is the techno geek in the family.) And if this card is the right thing, all I have to do is download GPS software?
Thanks for your help.
