Hier gibt es ein Tool, mit dem man die Reihenfolge der Karte einstellen kann. (Basemap = 0)
Falls einem die Anordnung der Karten nicht passen sollte oder man die Routinginformation mit Custom-Map oder Topo verwenden möchte.

Erklärung:

The program ChangeDrawPriority is used to change the draw priority of the maps. For instance CNNA8 has a draw priority of 30 and US Topo has a draw priority of 20. If you have maps from both products installed for the same area US Topo is displayed first, then CNNA8 is displayed so you can't see the US Topo maps. Say you're driving through the mountains and want to see the Topo map, but you also want the unit to route you to a destination. On the 60CSx you would have CN calculate the route, then you would have to go to the menu to hide CN so you can see the topo map. Then you pull into an area to take a look at the secenery and the gps decides you went off course and recalculates the route, since CN is hidden it will calculate the route from the routable basemap. Using the program I can change the draw priority of US Topo to 40, now when both CN & Topo maps are loaded the Topo maps are drawn on top of the CN maps. Now since the CN maps don't have to be hidden, routing will be done based on the CN maps instead of the basemap.
Hugo has CN type maps and Topo maps of Hungary, in this case both are routable however the routing on the CN maps is better since the Topo maps will route you the wrong way down one way streets. So the patch I provided is specific to the TopoGuide Hungary map to disable the routing on it. Then the draw priority can be changed for the TopoGuide map so it is drawn on top. Now he can load both the CN type maps & Topo maps and have the unit display the Topo maps and route on the CN type maps. Without the patch the unit would route on the Topo map instead of the CN type maps....

Nachtrag:
Sehr elegant geht dies auch mit dem Programm: IMG2MS
IMGFILE- 2- MAPSOURCE Version 1-5-3 mit Support für Drawpriority (Karten -Anzeigereihenfolge)
http://www-user.tu-chemnitz.de/~moth/IMG-FILE-to-MAPSOURCE.html
Es geht auch mit: gmaptool.exe http://www.anpo.republika.pl/download.html
Beispiel:
1 :CN9NT auf DP 25 und Topo auf 32: Ergebniss, es wird die CN9NT angezeigt,
2. Cn9NT weiter auf 25 und Topo auf 30 : Ergebniss: es wird die Topo angezeigt.
Werte der Drawpriority über 30 werden ignoriert und vermutlich die DP auf null ? gesetzt.
