This is how you would create .rmp raster files for the New Explorist Series from National Geographic Images.

You can view the exported maps from NG State series on New Explorist X10's:
(1) Create a Topoquad RMP file from National Geographic TOPO! State series exported map.jpg
NOTE: the RMP files will fit very well when using the Custom grid and Snap to Grid features.
(2) Convert Topoquad.rmp for use on Magellan eXplorist X10
