Looking at your message again, you may be looking at the basemap and not the detailed map.
Painful as it my be, as an absolute last resort, RTFM (Read the Fine Maunal).
I'm doing that but see no solution. I received v6 and downloaded 6.5 but it doesn't have it. I had expectd that Map Source would because it and Google both use NAVTEQ data and Google works. Apparently Garmin is not using NAVTEQ's latest offerings.
Oops, pressed "Post" too soon.
Again, MapSouce is just the viewer - the Map Set you should have is City Navigator. I've noticed lately that the street level detail doesn't show up until you get down pretty close.
I'm assuming that you're looking at the PC - if so, make sure you see "City Navigator North American v6 in the upper right hand corner. Just to the right of that, set the scale to 1.5 miles and detail to "Highest". You should see street level detail.
If you're looking at the 2610, look at the lower left corner of the map - you should see the scale and either "Base Map" or "Detail Map". Zoom in to a scale of less than 3 miles and you should see "Detail Map" and street level detail. There is a option to set map detail on the 2610 under the menu selection.
This of course after you do what Ron suggested and load the appropriate map detail.
If you like, tell me where you don't see what and I'll go looking there.
