The system in the dads touraeg (or however its spelt) is not working, does not play CD's. CD changer in the boot and satnav headunit but that dont work either. He is bored of listening to the radio and wants something sorted, does anyone know anything about trying to sort the issue, either by troubleshooting the current jobby.... or fitting a aftermarket system. He wants it to integrate with the controls on the wheel etc, as said it has the cd changer in the boot. It something i know nothing about so putting it out on here Thanks
