Saldous,

The Map Data is Better than most GPS systems that I have have used before (Hertz never lost, Ford expiditon). My system works great. Keep in mind that the data is loaded from a CD, so it is not the system itself that is bad. It also means that the data can be updated. Maybe the Data on the CD for the UK was bad at that time. Here in the US you can read the reviews at circuitcity.com or other sites. You will see the owners all love it. There is an N2 which is not widely available it has different feature it is not a replacement for the N1
