I've looked at the radio and the Rezesionen long. Also have other major manufacturers envisaged. But about 500-800 for a radio with touch screen? No Way. This goes the same times garnicht.Zudem I have a Navi and a smartphone with GPS. So once again get used to other software I did not want. The installation went easily quickly and easily. Only the two lines in + plug swap had in my Astra G. That was me, but previously known. I can only say my stations are found immediately, here in the deepest mountain range not self-evident. Sound and BedienŽnung I find with the onboard speakers more than ausreichend.Bin but also not a professional. Although, my advanced age, yes I hear house, funk, soul, pop, super sound. The menu is self-explanatory. Geil? (Must be the review)? I think it worked the Bluetooth connections with my Nokia N8 immediately. Even downloading the contacts. Excellent. Micro and handsfree 5 points. Again, the phone understands a partner even when driving faster. DVD runs super, CD's, and USB as well, so wass more could you want. I have SD card is not used ... All in all, highly recommended for me. Buy now a reversing camera and will also test these gimmicks. 5 stars for the processing 5 stars for the service 5 stars for the Amazon Service 5 stars for the rest MFG Black
