Arguments for the Navi: "Lifetime" free map updates and TMC-Pro. With TMC Pro, I had already had good experience with the old Navi.
After I received the device, I first reference to the downloaded manual personal settings, such as addresses, covered. This was a good start.
There were problems connecting to the PC. I have - in advance - to download and install the software for the navigation of the Becker homepage. When connecting to the PC according to the manual of the software Although the Navi was detected, but it could not connect to the program are made. After several attempts, I then discovered in the operating instructions for the device that the program is stored in the navigation system and should be installed from there. Made - done, and lo and behold: it works fine. I then loaded the first place, new maps and can be installed. This went much quicker and easier than with my old Medion. The map corresponds to the IV. Quarter 2011th
Meanwhile, I have the Navi on some - can test routes and it has carried out his task perfectly - I know. Clear displays and information, particularly when replacing the BAB or when turning, it is very helpful because the lane display.
I initially used as display the map in 2D and 3D plug (due to screen size each with directional arrows). Which view you choose, is a matter of taste.
Well I also liked that you can adjust the speed at which overrun, separated by inside and outside of the village, you get a warning. Many other devices, this setting is not made well.
One problem there for me even when connecting with my Nokia 701 smartphone. The devices recognize each other, but there is no connection. Since in several attempts with other phones - even Nokia - has worked without any problems, it will probably be due to my smartphone. If one has an idea how the problem could be solved, I would be grateful for hints (Settings: Bluetooth active, visible for all).
The clarity of the display also made me - probably due to its size - completely convinced. Many settings can make to his personal feeling; including election of the Speaker / -Innen.
The TMC reception was so far also completely sufficient. The antenna cable is connected to the power cable, but can also be installed separately. For this will be even two suction cups.
The active support is also much smaller and easier to handle than with my old man.
Still could not be tested the Situations scan; here should be planned based on the time of day and the traffic and your own driving behavior the route.
In short: Who is willing to spend much money, should definitely access, in particular, the "lifetime" free map update should be considered.
Addendum of 16/06/2014:
After more than two years of intensive use, I am using the Navi - apart from small things - to be very satisfied. The connection to the computer works without any problems. Before the last map update I have, however, yet used a memory card, since the internal memory for the amount of data is obviously too small. I therefore recommend the same Mitkauf a corresponding memory card (I have a cheap 8GB card is inserted).
Meanwhile, three other family members have the device; which are also fully satisfied.
When inserting abroad (Netherlands, Poland, Czech Republic), the Navi has also made reliable services. The previous negative reviews are for me largely incomprehensible.
