Can anyone help? I have had a USB box fitted by a dealer to my new 08 C4 cool, controls all work but it does not display on the screen. The screen display is the option A on the Radio manual not the more detailed option C. In the usb box manual however it seems to show both options for the display type. I am not sure what radio specification I have but may be able to find out. Could it be that the dealer has not fitted the usb box correctly or is it the display screen? Would appreciate your comments. Cheers.
