Thread: Costa Rica Navsat map up to version 6.4

@fuevarde, it's really a little hard at first, but this forum is all very well organized and intuitive navigation; try it!
Specialty the stick treads is important you read carefully! The rest is simply! Don’t give up!
The Mapsource has been discontinued by Garmin, and only the Basecamp keeps updating and adjusted to deal with the new maps increasingly complex (the last can read the maps in your SD after you correctly install then)... Use the GPS to calculate rotes and you don't need the basecamp at all.
However, the simplest and recommended that a beginner make the simplest and most effective; forget the PC installations (which still a bit puzzling; you will almost never use then, like the rest of us) and deal only with the maps to SD (.img extension) and gimgunlock (the second link below) that unlocks smoothly and without creating limitations use. Read the topics below, there is all information you want (also suggest the Google Translator, if you have difficulty with English).
Or the most simply! Put the .img file in SD/map directory, and the POIs in SD/Garmin/POI (create the folders, if they not exist yet), unlock the map (drag the icon from the map and drop it onto the icon of the gimgunlock.exe); and that's all! It's done!

A big hug, and ask more questions if needed.
However, all information you need is in the first link, and the program is in the second!
PS: catymag already response, but she has to care about this entire huge site and don't have much time to explain tip by tip as you demand, so, I assume that... Later you will understand she's response.
