Good radio with little quirks

First I want to say the positive things. It looks really good and can be adjusted by the color choice of any interior. The sound quality is really really good and a lot better than my old Blaupunkt.
The display is easy to read.
Now the negative things.
The operation of the joystick is not always easy in an imperfect road.
But what is most annoying is the fact that it sometimes has a right Macke. Suddenly appears on the display only "Reading" but since then nothing happens more. Had it continues to reinforce already 2 times within a year to reset by pulling the power supply on the radio.
In winter, it often happens that everything stays dark, the radio is playing, but skipping songs and louder / quieter make nich is possible. Or it is also more "Reading" because without that anything happens. Here, however, helps one off and on again.
Therefore only 3 stars
