Yes, the station/cd info never showed up in the dash display. Also the unit locked up meaning I was forever pressing the reset & setting it all up again, I then bought a sonic unit which is now for sale on ebay as I have sold my A4.
The wiper motors have an ignition feed to them, so once you switch them off you have a feed to park them in the right position. Maybe this circuit is fused separately & there is something amiss with this circuit or it's earth??
You will need this as it will power up the rear amp, also adapters to convert one of the Fakra connectors to ISO
Taken from another site.......
To enable Cruise Control and DIS, you need to do the following:
1) Open VAG-COM (connected to your port and ignition in position II)
2) Click on module '16 - Steering Wheel'
3) Go into 'Recode (07)'
4) The only bit in the code you need to change is the second...
