The radio has a good sound, DAB works well, everything else as expected. The swabs come by following disadvantages, which could be eradicated by judicious programmed firmware: * Anschaltknopf is not illuminated at night * After switching occurs first three seconds no response, until the lights go on * Sound settings must be selected cumbersome over several menu clicks, the distraction from the road * What's the most annoying: you have (about 40 gigabytes for example with me 20000) inserted a USB medium with many titles, the reading of the medium takes 35 seconds until the music starts. Unfortunately, the reading does not only happen when turning, and every time you turn on the radio and back to USB, or when a traffic message is automatically displayed. Always wait that long annoying. It would be no need, every time the whole medium durchzuscannen .... For 2 star deduction.
Addendum: It has not shown a failure: Taking the panel from (anti-theft ...) and puts it back off, then you can no longer switch on the radio! Only when you press the reset button with a needle, it's back.
