Ok thanks for he help. 
So where would I source one of these?
I got some after market bits can’t remember part numbers as it was a long time ago, but if you search on here, google or bing it you will find the right answer. I think i used a Parrot bluetooth module with a module to connect into the car. 
Unless you get the VW Bluetooth module, if you have the MFSW, but costs up to £300! I which I did after upgrading my radio. Wanted to go OEM.
