Also, I’m going to try to another use for the CityXplorer maps. I put a U.S. planimetric map by ibycus (USA2)from GPS File Depot, along with the Denver & Las Vegas CityXplorer and the CN North America map. I’m driving to Las Vegas this week from Denver, so I’m hoping (expecting) that the ibycus planimetric map shows up in the areas not covered by the CityXplorer maps, instead of the CN North America Map. My simulated run seemed to work. Unless I have the CN north america map activated, then the Garmin uses the inferior world base map for the routing, so having that activated is the only reason I have a question as to if this will work. Also, in messing with this combination of maps, I noticed that the Garmin – in car mode – does not use the CityXplorer maps for routing, but uses the underlying map – either the CN north america or the global world base map.
