a lot of potential, but is apparently buggy firmware

The radio should the existing Kenwood KDC-4547 to replace me. With whom I have always been very satisfied. However, the KDC-5751 is better with a 3-line display, individually adjustable lighting and SD card slot. That would be worth an upgrade.
My Experiences:
+ Grippy knobs (not self-evident)
+ Display is large, well-configurable and contains a lot of information
+ Lighting can pretty much vote on the dashboard lights color
+ Log function is awesome flexible
so far so good.
Nevertheless, I send it back because of the following negative points:
- After auto scan are in the Present list only the preset buttons and the frequencies, but not the station name. And this despite all the station names were displayed during the search process. This also applies to the log function of the station you were listening. Only when I anspringe a station, the station name is suddenly miraculously yet available. This is in my opinion completely useless. Consider the following scenario: I'm going somewhere by Germany and start the automatic tuning. Then I would like as a result of course, a channel list, and no frequencies list.
- The navigation on the USB stick is - compared to my predecessor radio KDC-4547 - caves slowly. It scrolls repeatedly in the blank screen inside, and a few seconds later then dip the MP3 tags on. That maybe I could understand if I had connected a slow, because mechanical hard drive. But not in a USB flash drive.
- The radio has crashed several times. This manifests itself in the fact that in the middle of the operation, the screen suddenly becomes black and the Kenwood logo is displayed.
- The entire front of the radio consists of glossy plastic. We see it every speck of dust, every scratch.
Conclusion: Well thought poorly done.
