Summary: Just thought I'd put a 2015 relevant review here. Perfectly good in 2007, but onsale currently for £140. For this money you could get a cheap smartphone which could get traffic updates (for free) on google maps and would be just as reliable as this.
Summary: Had it several years without a problem. I get regular map and traffic updates from TomTom that I have to pay for. I see most modern units seem to have Lifetime updates that are subscription free
Summary: This TomTom has been a helpful companion, especially when I downloaded the French maps for last summer's holiday. It is very useful on a number of fronts. Its one glitch is its tendency to take a direct route through B class roads, even when the setting is at 85% motorway use.
Summary: Used this for a few years now, has served me well. The additional FM traffic aerial has saved my bacon a few times too. The battery is tired now, but I might replace it for a few pounds, and hope to get a few more years out of the Tomtom.
