My friend own a 2008 Audi A6 with MMI DVD based color screen. Does anyone have successfully linked up a Sony Walkman to the MMI and been able to control the Walkman on the MMI screen. There is an adapter cable available but not sure will it works or he need anything else to perform this task. Walkman model is NW-A3000, it works perfectly and there is no reason to go out and buy an iPod.

Thanks for your input.
