FAQ: Can I use different types of maps together?

Yes, you can. You can combine all compatible map types together, until the 115/243Mb memory is full anyway. The Quest has a built in priority system, so it only displays one map at the same location. Worldmap has the lowest priority, City Select the highest, the others are somewhere in between. So, if you combine City Select with Worldmap, you only see Worldmap maps where there is no City Select map available. You can however force the display of lower priority maps by disabling higher priority maps from the MapSource Info menu on the Settings screen.
