Hello, I got the part in March in my Astra installed. The installation was easy, as well as the operation of the device. The sound is also great, I've yet wished no better speakers in the car, and I have a devil sound system at home;) So far, I also had no problems with CDs, the radio has all accepted. I was amazed also on the fast playback of MP3 CDs, former player searched for inserting an MP3 CD only the complete disc. This one does not, this radio will play the same drauflos :)
