Don't waste your money
I tried this product in the "Interior" of Sao Paulo.

It did not have a listing for the airport that we flew into. Using it to give directions from the airport to our destination was a disaster. It wanted us to go through every small town and down the frontage roads of the "freeway", rather then stay on the "freeway".

At our destination, it wanted us to drive the wrong way on the one way streets, was off aprox 100 meters, or one street all of the time.

Based on what I saw, this product is not ready for use outside of the big cities.

Garmin Europe SD Card
Very useful product throughout the southern German countyside. Showed amazing detail and saved quite a bit of time getting around. A must have if you are directionally challenged.

Works well in UK
I bought it for someone traveling to the UK and they were very pleased with the map..it was used in a Garmin Nuvi 680.

Well worth the expense
I purchased this sd card for a trip I had planned to Scotland. This little SD card was the best thing I bought for this trip. We spent 3 weeks driving around Scotland and it always got us to our chosen destination. If it hadnt been for this little card we would have never been able to see as much as we did. Having the GPS took allot of stress out of driving in a foreign country. I also used it in pedestrian mode while we were in edinburgh to get to places there. My husband and I would have never survived our trip still speaking to each other without this wonderful tool. If you are planning a trip and you will be driving just spend the money and enjoy your trip. It is the best money you will ever spend.

Phenomenal - Worth Every Cent
This little SD card saved our vacation. Typically we tend to rely on maps and self navigation, and it makes for a tense vacation when we're arguing over roads that aren't there, places that are impossible to find, etc. This time, we bought the SD card for my Garmin nuvi 660. This little gem got us to the most remote areas of southern England imaginable! Not one of our coastal locations was a problem to find. In one case, we stayed in a "town" that was literally three houses amid the moors. No road signs, one-lane roads, and no problem at all with this map! It's worth every cent. We found another retailer who sold it for much much less, but knowing what I know now, I'd not hesitate to pay what retailers here are asking for it!
