Installation in my VW Polo 6N2 was simple, simply pull apart the polarity when ISO adapter and reposition, already all settings remain after received the key is removed. Sound is superhot with my mounted from Vorbestizer magnate boxes with little EQ adjustment. Color I have on red because blue and the darkness disappears. The display itself is dimmable. Connected via Bluetooth with my Xperia Z, navigation announcements and stuffs funzt properly over the radio. Music plays from the iPod. A long press on the MODE button (back button) can switchen in the iPod mode, so you can use the Musikapp on iPhone / iPod. Otherwise then is encouraging ipod only "accessory connected" The remote control is superhot whenever I screw on the car and vonner tailgate will Seppen. Often done so far. Just pure comfort
