Markaf makes a very valid point.
I bought one last year and returned it.. In a way I was a casualty of advertising. In my simple way I thought all I had to do was type in the name of where I wanted to go and it could guide me there avoiding the peages. Sadly of the first four places I tried to go, I could not convince the machine that three of them existed. I had over estimated its and my capabilities. In a 3500 mile trip I took two wrong turnings and spent an hour trying to find the right road out of Merano. Once (in Gorltz) I had to ask where there was a guest house and was kindly guided there by a local.
They can be useful but might not always have the answer you want. The find a local garage/guest house etc, feature should work as it will be guiding you to somewhere it knows. It does seem to know most large cities which is where i need help the most and which I tend to avoid. Only twice was i in need of help, Merano and Gorlitz.
I do tend to navigate now by following road signs, I used to use road numbers but they change so often it is now unreliable.
As soon as I find one with 2011 maps preloaded I will buy another if I can get one with a headphone jack. I will have a much smaller expectation of its capabilities so it will work for me.
