What is CenRut?
CenRut is a community-based project to create and distribute GPS maps of Central America(freely to humanitarian organizations). The project covers El Salvador, Costa Rica, Nicaragua, Guatemala, Honduras, Belize and Panama.
How do I load the maps onto my Garmin GPS? (GMAPSUPP.IMG)
The simple Garmin method(not free, contribution required): Simplify your life and support the project! If you have a Garmin GPS click on this link:
to save the GMAPSUPP.IMG file onto your computer. Then connect your GPS to your computer and save the file in the /Map/ folder on your GPS. After saving the file to your GPS, disconnect the GPS from your computer. That's all!
The complete Garmin method: please refer to the complete Windows or the complete Mac method below, as appropriate, then download the installer below(not free, contribution required):
Cenrut installer for Mapsource and / or BaseCamp For Windows:
Cenrut installer for Mapsource and / or BaseCamp For Macintosh:
If you have any problem please post it on in our forum. Thank you.
Note: addresses in Latin America are unreliable, so you need to search by the name of the Point of Interest that is your desired destination.
After loading CenRut onto your GPS(with either the simple or complete method), the file should be in this folder on your Nuvi:
How do I know if the Cenrut maps are correctly loaded onto my GPS?
Start your GPS and go to Tools>Settings>Map>Info. You should see the following:
OK, I have verified that Cenrut is loaded onto my GPS and appreciate all the hard work, now what?
Send me a courtesy email(optional) and tell me where you are going! My email address is at the bottom of this page.
Random note about car rental in Costa Rica:
Be warned that car rental insurance is a bit of a racket(Adobe RentaCar might be an exception). Even if your rental company swears that the quoted rate is all-inclusive, this is usually not the case. More info here
Can I send data corrections for the maps?
Yes! Please send waypoints and tracks you have recorded, or just describe in an email the item that needs to be corrected!
How good are the maps?
In six of the seven coutries, they are better than the other options we have seen. The seventh country is Costa Rica, which is lucky enough to have three great options: TRACKIT (commercial), NAVSATCR(commercial) and CENRUT(free for development organizations and contributors).
Why do you do this?
We believe that this is an immensely valuable project that allows us to apply modern technology to help raise the standard of living in Central America. Plus, we enjoy it.
Who are you?
The project leader is Willy, who lives in El Salvador. CenRut also works with similar projects in other countries, including Venezuela (gpsyv.net), Argentina (proyectomapear.com.ar), and Peru (perut.org).
How do you finance all this?
We used to be able to generate enough funds indirectly(Google ads, Amazon referrals, donations) but those sources have decreased over 95%, so we are asking for contributions. Plus the quality of the maps has reached a point that they are well worth the price.
How else can I help?
Send me an email after you use it, and tell me if anything needs to be corrected! Also please send any favorites/waypoints that should be added! Email address is at the bottom of the page.
