Garmin 60csx base map

I run the topomaps with the sled map overlay on mine and it's fine on my 60!

OK my Topo map dvd should be hear today. If I download both Topo and the snowmobile trail map to the SD card at the same time, will it automatically overlay the trail map?

Do I have to load them into mapsource in a certain order and then download them?

Is there a setting on the GPS to allow overlaying( I havent seen one)

Or, is there internal memory on the GPS that will allow me to load the Topo to it, and then the Trail map to the SD card?

Thanks for the help guys, just want to be sure to do it right!
