Best SIMPLE Non-Speaking GPS For Mexico
My son-in-law just asked me to get him a GPS. I told him he would probably have to keep it double sealed in zip=loc bags on his 24' lancha. A basic GPS with good reliability up to 5 miles offshore ...

....you could also download all the World's DNCs (declassified patches) from the NGA; Mexico is comprised of DNCDX014 & DNCDX013

...he'll need a very high-resolution shoreline vector layer, too (at MSL) and port approaches, not the crappy generalized shoreline layers found in terrestrial GPS units.
I would have suggest that he use OpenCPN (a free GPLv2 chartplotter AND GPS navigation software), however, free NOAA RNC geo-referenced digital images of the charts and ENCs vector files of chart features (in S-57 format) are only available for the entire Gulf of Mexico to just north of Belize City, and not the Mexican West Coast any further south of Vicente Guerrero (Baja Norte)...eg. using OpenCPN, he could plot his own navigation (at home on-shore), and output via the Route Manager, waypoints, routes, tracks and layers to GPX format. GPX files that any cheap water-resistant GPS could ingest for water navigation (connecting the GPS to his laptop via USB or serial cable).
