base maps and Central America

I've read lots of threads on maps for Central America and have still not found anything that will fill my needs for detailed maps of El Salvador and Guatemala but can deal with what's available I think.

I will be working in El Salvador for the next year and will probably take my GS down after Christmas but will take my Nuvi 550 down as a navigation aid while traveling mostly by truck. The one I have came with North America Cities as the base map and I purchased World Map to use as a base map in El Salvador. If anyone has other suggestions for additional maps, please let me know.

Questions: Is World Map the same base map that is in my 76S? Also, when I went to load World Map it required that I select a map. Is there any way to just load the entire world map? I could not figure out how do select all so I just mostly selected the western hemisphere but since I do work in other hemispheres at times it might be handy to have on the Nuvi.

Thanks in advance for any advice and if you're heading Central America way after Christmas, let me know.

I thought the world map was the same thing as the base map?

The only GPS maps for central america that I have seen are the smelly biker maps. They have V1.6 which is detailed but not routable and they have the V2 which is basically the same as the Garmin world map and routeable.

I cannot vouch for the accuracy of the detailed smelly biker maps, never used them real world yet. You might get some input over on the Latin America regional forum though.

I know there are a couple of dirt bike tour outfits in El Salvdor and when you get down there you could find out what they use.

Also there are some suggested maps over on Zumo forums, but dont think there is really anything for CA, other than smellybiker maps lited on that site. http://www.zumoforums.com/index.php?topic=3572.0

Take my advice with a grain of salt. It's been a number of years since I used Garmin's WorldMap, and in addition, I've never seen the basemap for the 76.

I am guessing that WorldMap is slightly more detailed than the basemap, but far from detailed. Mostly (in my experience) it improves upon boundaries and shorelines and has more cities and smaller towns in the database. There are a few more highways and major roads shown. Water features such as big lakes and rivers are shown which weren't on the basemap of the GPS I used (An old eTrex Legend, if I remember).

At the time that I used it, I came away with the impression that it was barely worth the purchase price. Unfortunately, I don't remember what I paid for it, nor do I remember the version I had, and it's long gone.

Thanks for the info, kind of what I thought. I'll be there for almost a year so maybe I can build something myself. The Caribbean maps looked interesting but for some reason were not available.

Try out the smellybiker V1.6 maps. They do have quite a bit of detail for CA, but as to how accurate it is I'm not really sure. IIRC they cost about 50 bucks to download.

here are some screen shots of the various maps around the San Salvador area.

Gamin Base Map







Smellybiker Routeable World Map






Smellybiker Wanderwest V1.6





Not really a whole lot of difference except for the Smellybiker V1.6 which displays many more towns, but really no more road detail in this area.

Hope this helps....

Cool, when pass through on my 990 next year, maybe you could show me some of the local trails.

The DRZ would be perfect for Central America IMO, mud, mud, and more mud.

When are you planning on going through on your 990? I'm trying to decide if I want to bring my GS down in October or wait until after Christmas. Either way some company would be nice. Buena suerte.

PS the base map is almost useless here.

Dont really know yet as the only plan I have is leave home in a few weeks or thereabouts, and head in a roughly southerly direction for the next year or so.

But, if I were to guess, I might be through El Salvador before the next wet season.
