This is what all the oldies say too and ive proven to all of them that maps are a thing of the past now. They all went out and bought tomtom's a few days after.

I do 60k+ a year and have tried all types of sat nav and the TomTom's are by far the best in every way!!!

Its the best selling system for a reason. Just take a note of how many tomtoms you see on the motorways compared with other units.
