South America maps for Garmin
 

I have a Garmin with maps of Europe (free updates)

I plan to ride in Chile and Argentina.
So I am looking for maps to add.

Where is best to buy (Or use open maps) ?

Thanks

(I have one time bougth a SD card on Ebay for central America.
It was just to plug in and use. No download and Installation SW that does not work. Or corrupted files or...)

Better, easier to use OSM maps. Just download the countries you want to travel and put them on the mini SD card.

And it is Free

We used free OSM on a Garmin in most of South America, and both in cities and way out in the middle of nowhere they very rarely led us astray.

Not all that intuitive to download and install them but one you figure it out once, the rest are easy.

GPS maps for Chile
 

I downloaded the free OSM maps.
Works great for Agentina.

But for Chile and Boliva seams to be useless.
So little information
E.g Ruta 7 in Chile is not visible at all

?
Named Carretera Austral in Chile.. the reference number is 7 and that should appear as the shield number.
Looks fine to me.
See https://www.openstreetmap.org/relation/9402626, you do need to zoom in for detail.

OSM Maps also worked fine for me all over South America. Only country I had a few problems in was Peru where on a couple of occasions streets they routed me down ended in a flight of stairs - not a major drama. Google maps also struggled here as well.
