MS Streets and Trips provides a base map of Mexico.  The detail
is not as great as it is for US and Canada, but is shows the
main highways.  The 2002 version is available at Costco for 
about $40 and they might still have the $20 rebate.

I've included a screen capture of the area around Nogales.
You can see the diference between the US side and the Mexico side.

Subject: [Az-Geocaching] Mapping software for Mexico??


Does anyone know if there is mapping software for Mexico??  I know
Mapsource MetroGuide and Topo doesn't do it.
