hi.. posting here on behalf of a mate...

Essentially he had the RCD510 on the Golf VI.

After upgrading to the RNS510, and configuring via VAGCOM to turn on "Navigation" and "BAP on the RNS510, he is:

1. able to listen to tracks
2. BUT not able to use his steering wheel controls to control the volume/track

Must we do something different on the Golf VI?

Thanks in advance for any tips
