Visually top, behind - well

Wanted to become 4 TomTom devices to try out an alternative, especially since increasingly revealed problems with the update via PC.
But it goes even worse, I was not aware at the time of equipment purchase.
But now from the front:
Visually, the part is top. How does the device feels really good and stands out from other devices from refreshing. The windshield mount is good and the device is mounted very stable despite the high weight. The magnetic closure allows for easy removal from the charging cradle and is also very good.
But now to the disadvantages:
Installation of the software requires a very high level of computer skills, one must not assume that everything goes without saying. In my example, to be carried out by an update to German was both a display and as a voice command away!
The support is in permanent hibernation and is really bad if you're in a hurry you should for nerve sparing it better not try. This can for example. TomTom much better.
Available on the Internet OVL's can only be read conditionally, because the symbols are not based on bitmaps special from so-called KML files. While Thus, the overlays on the screen but are equipped with General symbols.
The standard OVL's are arbitrary, for example, does not appear directly on the site located at finding the nearest furniture store a furniture chain, but one which is 70 km away -. Great ...
But now the real problem:
software for route guidance stands out decisively from that of TomTom from, it can be assumed that the routing - no matter what chooses route guidance variant (Eco-fast-short, etc.) In general, do not choose the right path. I mean not any nest on land but the capital. Even if one ignores the instruction and continues further, the software is not able to recognize alternatives. Only when the difference is even more than 30-40 km, the system grinds to the logical and much better option - the one has chosen itself - a. The other day I was even piloted in another big city into a dead end!
Bottom line: If you are not able to ignore the route guidance at the crucial points, either because you are not really familiar with the area or not blatant To / recognize wrong turns, one should stay away from this unit. By the way, in my opinion also does not work at the traffic-related Alternativwegführung.
Even at the end: if you leave the device always at the charging cable can be assumed that the battery no longer exists later than in 2 months of operation.
