The crux is that the antenna port of the radio with the antenna cable of our vehicle (VW Polo, Bj. 98) is not compatible and is also attached to any type of adapter for the antenna connector. Therefore, so far I could not even the radio "finally" be installed in the vehicle, but'll only need to check with the retailers, whether there is an appropriate adapter.
During a brief test (the unit was very quick and "foolproof" angekabelt and could therefore be subjected to a short function test) made everything a high-quality impression. The key might be to press a little easier, but enjoyable is definitely that the volume is regulated with a dial (the current radio regulation is done with buttons, which is very ineffective if you quickly GO UP the volume wants runterregeln) ,
A complement of this review is expected to follow even if we finally built the device in the car.
