thinking about buying this:
however, i know NOTHING about GPS units. i know garmin sells memory cards and additional cd rom maps, but i was wondering if data could be uploaded w/o a memory card. reason i ask is because i stumbled upon detailed canadian maps and i'd like to buy the gps for under $200 and not shell out another $100 for a mem card...and still use the canada maps.
also, how accurate are these things out of the box w/o detailed maps??
what B&M stores sell these so i can check one out?
i'm mainly interested in personal experience with uploading maps and the general usefullness of such a unit.
