As mentioned above, it's a basic Connect Nav unit. The screen doesn't show full mapping, just arrows that point which way to turn. I believe it uses the same map disc as the Connect Nav+
As far as I know, there is no online instruction manual for it, but it's operation is described in the early paper Connect Nav / Connect Nav+ manual that was supplied with the car. Apart from mapping, all other functions will be the same as the CN+ which are described in the downloadable manual in Eklipz3k's link above.
