Got City Navigator mapping so now I have set it up the way I wanted so it is really two machines in one replacing my old Aldi road GPS and Garmin 60 CSX.
I have set up two profiles:
The bike one opens up Oz Topo mapping and the menu has shortcuts to tracks, track manager, compass, tripmeter (with big symbols) and Profile change.
The car one opens up City Navigator mapping in the Nuvi display mode with Menu shortcuts to Where to, mark waypoint, trip meter (standard) and Profile change.
Allows me to navigate on tarmac to the start of a ride in Car profile and then select profile change to Bike profile, select a track file and hit the dirt.
This thing rocks.
