Yes, I already do this with my garmin map. It has elevation data,
"base" map and maxspeed layer to be switched on and off individually.

Have a look at these commands that explain how the German "All in one
Map"(not my work!) is created:

You only need gmaptool and the right family and product ids in your
"layers". :-)

But I use SRMT, as I don't know how to use ASTER data.
