FYI If you have CitySelect 6/7 and go to the garmin site to unlock maps or browse you may be told you are eligible for an update to CN 8 dvd, this seems like a great idea. I ordered the update, received the dvd, installed it(1.68gb), went to unlock map data and THEN was informed it would be 75.00 . Well I really didn't need the latest map data, so I opted out of this update, then I found that my mapsource had been updated to a newer version, that my harddrive was low on space, that the GPS tab in mapsource was gone . O K so to sum up this rant newer isn't allways a good thing, I was able to remove CN8 and reload CS7 so all is well
