Navman iCN 510
There is a lot more detail on the Navman at my GPS website http://gps.wikispaces.com/Why I like it
There are some good brand/model features of the Navman.- It's compact
- Good quality touch screen
- Easy to enter destinations using a keyboard on the touch screen.
- Good quality cradle for the car.
- Back on Track capability - if you take a wrong turn, it auto recaculates a recovery path.
