Yeah your right! You load in the maps and you can zoom in and out and flag roads of interest. Then print out the area you want. I print a detailed map (zoomed in) of the area of interest then use my tomtom to get to a named road that is nearby. The other guys tell me that there is a route planning option on it but i am yet to use it.
there is a function where you tap/hold on a waypoint and choose navigate to... this brings up a direction arrow and other data...
is that what you meant??
