Bests & Worsts Reviews from Amazon

I just got back from a week long trip to Iceland that involved quite a bit of driving. We drove extensively through the southern part of the country (to Vik), through the Reykjavík-Keflavík area and also the western part of the country north of the Reykjavík area (to Snaefellsjoekull). I read the reviews of this map (obviously not closely enough) before I purchased it and thought that the negative reviews were perhaps due to folks needing more detail on minor roads and the like. We would be sticking to well established roads so i thought there would be no problems for us. After all if it's a NATIONAL GEOGRAPHIC map, they're experts in adventure right? And this is called an ADVENTURE MAP so I didn't expect major flaws in the map when it came to the main roads. I was wrong. On several occasions we were disappointed with the lack of detail in the map, that's a small headache and a problem but when driving in a country like Iceland you should expect some flaws as roads do change etc.. the minor stuff we didn't have a problem with and we figured things out as we went. What is unacceptable is that there are main roads on this map that are listed COMPLETELY OFF THE MARK from where they really are located. The inaccuracies cost us dearly one day as we wasted nearly half the day trying to get back on track after being thrown off course because of the map. If you are planning a trip to Iceland that involves driving do yourself a favor and purchase a different map.
