Hi, I recently had a similar experience and hope my findings will help you get the right unit (there are about 50 to choose from so it can be a nightmare!)
I recently purchased a Scirocco R with an RNS 510 unit installed; I did not have access to the 'phone' menu (pressing the button would mute sound) and very limited bluetooth functionality (my car would act as a 'headest' for my phone wirelessly but nothing else). Checking under the seat I found I had the bluetooth module "5P0 862 335 B". I'm unsure if this was an original part or retrofitted/swapped in the life of the car, however I did know it wasn't suitable!
I did some research and purchased a VW Premium Bluetooth interface "3C8 035 730 B". The module was plug and play; instantly unlocking the PHONE and BLUETOOTH menus, and allowing full bluetooth functionality and control for an Iphone 6. Success!
To tailor this to your (and hopefully others) queries, I used the following sites to find the right solution:

http://wiki.ross-tech.com/wiki/index.ph ... trofitting" onclick="window.open(this.href);return false; - Listing of code numbers for bluetooth modules (check for those with 'YES' across the board for full functionality)
Possible suggestions for full bluetooth functionality:
- 5N0-035-730-D (2010)
- 3C8-035-730-B (2011)
- 3C8-035-730-C (2012)
- 3C8-035-730-D (2013)+ Wifi support
- 3C8-035-730-E (2014) + Wifi Support
There is nothing to suggest that you *have* to pair up the module to the year of your car, however I took a punt and matched the headunit with a 2011 model and the results were spot on.
I had the advantage that I already had a system installed (So the box was a simple switch over); if you need the whole kit then I'd recommend

Hope that helps, good hunting!
