I've got a Mk6 GTi with the RNS510 head unit. Irritatingly, although it's got the phone button on the steering wheel and on the unit itself, it won't actually allow me to connect my phone via Bluetooth (believe an additional module is needed). When I purchased the car used from VW I got them to supply and install their version of the Parrot system as part of the deal so I've been able to make handsfree calls but not using the steering wheel or head unit button.
Is there any way of upgrading the stereo to do this and allow me to play music (Spotify etc.) via BT through the radio or am I better upgrading the entire stereo to something that gives all of that plus DAB?
Cheers
