The "NT" I'm refering to is a new map compression technology (i.e. "New Technology") used by Garmin in their newer GPS units (Garmin always uses NavTeq maps and that has nothing to do with them being NT formatted or not). Basically, the new compression format allows you to fit much more map data in the same amount of memory space when compared to the non-NT formatted maps. However, the NT maps aren't supported by many of the older GPS units
Since the Mobile XT program understands the NT format, you can use it with either the older non-NT formatted maps (such as City Select), or the newer NT formatted maps (such as City Navigator NT). However, in order to take advantage of the new live traffic feature, you have to be using the NT formatted maps.
City Select is identical to City Navigator except that its map regions are broken up into smaller chunks so that they better fit onto Garmin's older handheld units which don't have much internal memory available. Also, the routing directions are formatted a bit differently so that they fit better on the smaller screens of the handheld units
