worked in Germany
Was very useful Germany. It guided us around roundabouts, and even had tiny one lane farm roads in it. Was not entirely up to date but that didn't cause any problems. Can set the Garmin to "pedestrian" to use in the city.

Of no use in Brazil
The Brazilian map is of no use. I live here and used it on approx. 1'000 miles.
a) In the city, streets are lacking, have outdated intersections, returns etc. And the map is constantly off some 100 ft.
b) On the countryside the situation is even worse: the location of the streets, cities, intersections is off by several miles. Existing streets are missing, streets on the map are inexistent.
Result in both cases: The routes created by the GPS device are simply wrong. The wrong position causes the device to constantly recalculate the route (as it sees itself never at the actual location) in another wrong way. As for the wrong maps: I "cruised" miles over the sea (in my car), on the other side, the ferry boat Salvador-Itaparica "drove" on land. Cities are on the wrong side of a river (imagine in a country where a bridge may be an issue of 100 miles and up!). If I had followed the routes calculated by Garmin, I would have had to dissemble the car: the only way to follow Garmin's route would have been by a canoe ferry.
Even as a compass it is unusable: E.G. In case you are driving west (miles south of the road shown on the map) and you are approaching a road coming from the south, getting closer to this "southern road" than your actual "western road", the device thinks that you are driving north on the "southern road". Confusing? Yes that's what it is all about. You are constantly busy thinking "what does it show, what could that mean?".
Don't waste your time!

Works fine
Works perrfect in Brazil. In Recife, where I live, its poor regarding restaurants/POI. Delivered quickly.

Lacks atualization
The brazilian map requires atualization, there are shopping centers, streets and other places that are more than 3 years old and they don't appear in the gps guide. Besides that it works perfectly.

Exactly as described, a smooth transaction.
The maps work well in my Garmin Nuvi 350. This was a nice transaction.
