Thanks. So what else am I doing wrong because when I drop this file into my Garmin system folder and then try to use the Garmin, I see no change whatsoever. When I click "go to map" I only see US map. I don't see any option to get an Israel map.

From other google searches I found references to using a special app to install maps and something called a webupdater to change the firmware but they did not go into any details at all - as if I should already know where to find this app and what to do with it. Any step by step instructions for noobs? Thanks so much, if I can't get this to work, I'll have to return the gps while I still can.
