I'm about to come into S3 ownership for the second time (8L).

However, parts of the switchgear, namely the air con controls are worn and have lost their symbols (+/-) and are now just white.

Could you tell me where i can source parts such as these.

Furthermore, the car I'm buying has a normal cassette with the CD changer in the back. Can I change this for a Symphony II head unit?

If so, the Symphony II head unit is much larger and I don't know how this fits without changing the whole central dash layout.

Thanks for any help you can provide
