So. Even though my A3 falls under the guidelines of the car radio manufacturer, I had to buy an extra cable to connect to the radio. The car radio works, the Fisanzeige, the sound is not bad, but the radio has only a three-band equalizer. But It will not start without ignition, It is now and very lame in the operation, The navigation device and on the radio to crash very often, The settings are for today and for the money is a joke, The Radio itself takes a long time so that it boots up, For me at least, the rear speakers run after a few seconds after the radio was switched off, The display is hardly visible in direct sunlight, The advertised by the manufacturer for Air Display and the ultrasonic sensors, there is not, and I have seen in any A3 which hitherto, Support? There apparently is no, the manufacturer did not respond to requests for updates or the like. Oh, the black screen from the radio is a little brighter as the faucet with me. All in all a cheap car radio, which was, incidentally, already announced 5 years ago, which is sold at much overpriced.
