TomTom Pro 5150 Truck Live navigation device (12.7 cm (5 inches) touch screen, 8GB of internal memory, EU countries maps) The Navi is working properly, but when the truck mode is set, which is a good Navi past. In truck mode, the device passes on the plug are much longer (some 25 kilometers longer than car mode) by high loss of time !!! Live function very well, but crashes has partially repeatedly but (no connection or problem TOMTOM) has always been (is my third TOMTOM GPS with Live function) .Stauwarnung but is really awesome !!! Conclusion I would not buy it again because it purports simply to big unnecessary detours and so for me as a truck driver a lot more disadvantages than advantages brings. So trucks colleagues AWAY !!! Prefer to buy the TomTom Go Live 825M EU. One year free Live function and map update always free, but saved the best almost 200 euros.
