W211 with Audio 20 - audio socket?

[Gollom]

Is it possible to simply add an input socket so I can hear sound from my Creative Zen player via the car speakers? I do realise the tracks etc. will not show.

The W211 Audio 20 unit does not have a connector for an AUX input. I believe the options are Dension Gateway or something similar, or a bit more complex DIY approach possibly like here:
