Hi guys,

Looking to upgrade my car bluetooth and stereo to an RCD510. As my car is Jan 08 I think the CAN bus won't be an issue. I've read a lot of articles on bluetooth modules and bluetooth compatibility for MKV Golfs, however I still cannot find an answer.

I've purchased the Genuine Version B 9w7 Bluetooth Module from Ebay ($120 not sure if steal or not, the others were bluetooth kits at $360). From what I understand I'll be able to control my phone from the RCD510 but not from the steering wheel buttons.

I already have a bluetooth system in my car (Don't ask which one, all I know is there's a microphone behind the steering wheel on the cluster). I have a series of questions, and would love some clarification

- Do I need any other cables/harnesses to install this module?
- Do I need any VCDS coding? I've read somewhere that if the CAN Bus is coded the steering wheel buttons can work as well (Red MFD), is this true/false
- Do I need a Bosch or Delphi RCD-510 (I've read somewhere only Bosch works with 9w7)?

Thank you
