Thread: Multi maps on Nuvi 7x0/7x5

I use 60csx with Topo Canada (eastern part) ,Topo Quebec 20k maps, and Trak marine maps compiled in mapsource,and it works flawlessly. I use the class 6 micro sd card and the screen redraw is not any slower then with a single map product compiled. After all you are using only one map at a time. The one you select in the map setup menu of the gps. At least this is my experience unless I am missing something.
