But from the beginning ...
The device can easily be installed. The size has been mentioned so many times before. Commissioning also is very easy (even without Seitenweise manual). The configuration of the device is intuitive.
Now for the practical utility ...
First of all, the graphical representation is very pleasant but my opinion after a big disadvantage. The parallel display of 5 functions as an "analog hands" and digital value, everything turns out quite small. Means: personally I find the display too small that they can collect on the Navi with a quick glance. One has to very precisely plan looking to be able to read the small numbers. Very practical in my opinion. Large clear numbers without the Gafikschnickschank would significantly effitienter.
In the first (!) Long drive (about 45 minutes AB) smeared me the software then also unfortunately already from. (Has indeed already frequently mentioned here). Trying to restart the unit up acknowledged me with the statement "it can not be contacted, please switch off the engine and restart" ... very inconvenient on the motorway. After a later restart but ran everything again.
The display of speed and temperature, speed and average consumption are okay. But the function of engine load remained a mystery to me. I do not know if these are read directly, or calculated, but in an instantaneous fuel consumption of 3-4l / 100km from the onboard computer opens up to me not really a motor load of> 80%.
The Ökoberechnung left me with a mixed feeling. The visualization on the last minutes driven, as well as the acceleration and braking values are solved quite nice, but the eco counter of 1 (very poor) to 99 (best) with its colorful leaves but is more of a gadget without deeper meaning. Once I accelerate or accelerator is the value down. Toll, must up the mountain the ever be, and that I then consume more fuel does not have to me the computer then explain. The display gives me more of an accelerator pedal position. Rather, it would have been very interesting here, if the rate at which acceleration ecometer could, depending on the street because I'm the most efficient on the road. Finally, there is also a road uphill a ecological driving style. This may not represent the equipment but.
Conclusion:
In addition to the unexpected crash of the software in the first test drive, I see no benefit for me, unfortunately, in the functions, because I can not derive any information for a more efficient driving style.
Finally, I would like to say that I got a very friendly and competent advice in a telephone conversation with Garmin! There are unfortunately no points)
