The GPS only comes with a basemap which is useless. So you have to buy maps. City Navigator are the maps you want to buy. They will set you back another 100+ bucks but they are worth it.
Thanks for all the suggestions! YEs, the map cds that came with the device are the 3 disc set of TOPO maps. I can't even get THOSE installed...because even though my device is connected, it doesn't appear that through Mapsource it can be identified. Which probably means a driver issue, right? I'll definitely call garmin support tomorrow.
In the meantime, in addition to this issue, are you saying that the TOPO maps probably won't give me the detail that I want anyway? I would like to be able to zoom down to see street names at least! That's not so much to ask is it? Right now with the basemap, I see very few street names. So, do you suggest that I purchase the City Navigator maps for my unit? Then I'll be able to actually use it to search for specific addresses? Right now, "address" isn't even an option on my "find" menu.
Thanks again for the replies.
