Cane Pole, the gps comes with a 128 meg blank card. the unlocking , as the garmin software rep explained to me was for the CD only. this is to prevent us from "passing it around to our friends for free". you can only unlock to one computer also. But after its unlocked you can download maps to as many gps units that you have. this is my understanding. i'm still waiting on the CD to arrive. Also, i bought a much bigger memory card, a one gig. for only about $25 from a gps discount store on the net.Originally Posted by Cane Pole
