G'day, I got Topo v5 up on my Nuvi 2797. Looks good with 3D shading!

But I noticed when I select Topo v5, CN SENSIS & HERE are automatically deSellected!!! (Even OSM)

NOT happy!!!!!!!!! I was hopping to use the other maps to provide auto-routing. (Like I do with ozTOPO V3)

5m Contours & BlueChart Contours are OK.

Although TOPO v5 has contour lines at 20m intervals, I believe the web site refers to 40m DEM.
