Tflima,
I always go to Argentina, Chile and Uruguai.
The map Mapear is the best.
Have POIs, almost all hotels, fuel station and other things.
When i go to region of Bariloche, I go by Uruguay, to divert the police corrupt.
I enter the Uruguay Rivera-Santana do Livramento and Argentina by Paisandu-Colon.
But the last time, the road was bad.

you can to believe in Mapear.
