Nevertheless, a few negative points are available:
When unpacking, I noticed schonmal to the poor quality of the monitor. The display "shell" broke up at one end slightly - cheap plastic quality.
The operation of the - in my view quite unnecessary - Multimedia elements is also done rather poorly.
Here me the device is already crashed several times (goes into a Windows screen (ancient Edition) and is only at reboot properly loaded).
The touchscreen is also to operate only with very strong pressure ... it feels almost reminiscent of the very first touchscreen early 2000s.
Note also: For some cars the charger cable is probably too short! It has been estimated to ~ 60 cm and at least for me the length of cigarette is to windshield very tight
-> Conclusion: Navi's not worth it, the rest more. I am still happy.
