hello
I have added in an audi 6 cd changer in glovebox of my A4 avant 2005,
used the correct lead directly into the back of the chorus radio.
the cd changer fires up but when the cc/cd button pressed ,the message no tape appears
the paper instruction says may need a new configuration using vas 5051
does anyone know what to do as I have no idea .have played about with the buttons a bit but no luck
unfortunately I have no manual with the cd player
thanks for any help
