I'm on my way south through Central and South America, and I'm very interested if anyone knows about good solutions for navigation that can give me info on roads, backroads, and even topo for this area. We have a nuvi that I thought I should update with a Garmin World Map, but even this is quite limited in some areas. Any other ideas??? :-)
We have a laptop that can run map software (and the garmin nuvi 255w).
