I have just fitted my new RCD510 (with lots of hasstle from VW!) and have some strange changes from the multi-function steering wheels buttons...
Before, I had an RCD500, a Parrot ck3000 evo and a multi-can interface to enable use of the steering wheel buttons with the parrot kit. This all worked perfectly and the steering wheel phone button was used to make a call (via voise dialling) witht eh volume buttons controlling the phone volume during a call.
Now with the new stereo, the phone button does nothing when pressed once (but still does redial if you hold it, as before) and during a call the volume buttons do nothing at all. The new RCD510 says nothing different when the phone is in use where the old RCD500 said 'Phone'.
This is very frustrating as I now need to dial numbers from the phone, which is obviously bad. Does anyone know if something can be done with vag-com to enable the new head unit to 'see' the phone kit and allow use of the buttons, or is it something that a new can gateway would sort out? Wiring changes?
Basically, please help!
If anyone can suggest a fix that works, I'll send them some free stuff
