My comment is referring to the well Navigon 72 Premium (not live). Apart from the somewhat crappy software NavigonFresh (it crashes and severe, even on my Mac! And good interface could be better), it is fast, accurate (too must see where it passed, I'm not sure old tomtom one of my father would have done the same!) recalculates very quickly if we plant, pretty interface and super informative. Up to 3 proposed routes when entering with a good estimated deadlines. The 5-inch screen is very beautiful, I love the presence of logos / PI directly on the map (macdo logos, ibis, total station etc ... appear on the map) and the appointment of clear directions to take, route numbers and cities! Possibility to put its own IP to remember. Presence of the indication of the speed at which they drive and even an altimeter (well it is true that ... to say we -3m altitude on the heights of Cherbourg is not terrible. ..), activate the option for it to appear. The straps, the design which appears on the screen, it nikel one is caught off guard! Displaying speed limits pretty decent overall, can set the alert threshold ... really not bad! Automatic switch (if desired) of the day / night mode, 3D display (like 2D / 3D choice) very friendly to use. I disagree with the previous opinion, the display size of the information is impeccable, no need to have a good view, it is neither too big nor too small that occupies a reasonable space. I note just the touch screen a bit boring to use at times (not respond very well) and also that the support is not very convenient. I also think that from the point of view ergonomics there's better to do it, the menus are very rich but you still have to rummage a little to get what you want (where a tomtom is indeed a amazingly simple). The free lifetime TMC premium is nice too, a lot of information is displayed on the screen on the driving conditions and speed cameras (called - hazardous areas - which can also manually update) . I far from having seen everything, but I'm happy for myself and recommend this product again but can not be like first GPS.
