Scores 3.6 out of 5 from over 285 Amazon Reviewers (view on Amazon).
The TomTom Start 20 is pretty much on the way out now, as 4.3 inches is considered a little small for a sat nav screen. Newer models such as the TomTom Start 25 have a 5 inch screen. But anyway, the TomTom Start 20 offers straightforward A to B TomTom navigation and comes with lifetime map updates included out of the box, meaning you can update your maps for free 4 times a year. If you're after something pretty basic but reliable then the TomTom Start 20 will probably do you just fine.
