Only useful as a USB player

As a previous reviewer has already written, the radio reception is abysmal. All radio stations with me a continuous, albeit very slight noise to hear. Furthermore, constant noise interruptions occur when traveling by car. A good reception is only possible at a standstill. Because of this lack, I prefer from two stars, as an interference-free radio reception for a car radio should actually be taken for granted.
Playback via USB stick funnktioniert contrast perfectly. My 8GB stick is always recognized. Nevertheless, I'll deduct a point here as well, because no one coil in track. As some of my tracks go well over an hour, a fast forward is not possible.

Otherwise, I have no problems with the car "radio". If you are looking only for a USB player for less money, can be accessed here. Who, however, from time to time just want to hear radio, should buy another product.
