Having used tomtom satnav for years now i upgraded to tom tom truck. The idea is great and fairly acurate, and it does as a rule avoid the tricky problems of navigating a 44 tonne truck round the UK. But Dartford tunnel, it refuses to go under, and selects Blackwall tunnel in stead.
If no truck route found, and a car route is used instead, it avoids the weight restictions, rather than low bridges.
It chooses the shortest route, instead of the easiets (sometimes then quicker) route for trucks
no motorway servises, or truck stops.Nor has it any of te industrial areas on, and if in doubt, a weight limit is imposed. Ie all the containerports in uk is no acces for trucks??
It give the impresion of a developer sat in a office that has no idea of problems driving a truck, and it gives the impresion that TomTom have not consuted the trucking industri about what is needed.
But as a experienced driver, it is a great tool, just dont throw away your trucking maps yet!
