BlueTooth related questions (all BT questions go in this thread only)

[VW3]

Another VW Bluetooth module question to which I hope there is a simple answer.

I have a MY2010 Tiguan with an RCD510 (BOSCH 5K0 035 190 A) and it had a dealer installed Volk-L Bluetooth unit (NOKIA 1K8 051 730 B) which worked for pairing various phones and streaming music (sometimes)..

I'm trying to upgrade to what I believe is a 9W7 Bluetooth module (5K0 035 730 F), the connector is the same and the RCD510 appears to recognize the new Bluetooth module, BUT.. I don't get a bluetooth device available displayed on either of my phones (an iPhone and a Samsung). I believe I should see the VW Bluetooth module displayed as 'VW Phone'.. but nothing other than a message on the MFD (white) advising to 'Place cradle in baseplate'

As I had and used Bluetooth before in this car I didn't think any VCDS coding was required..?

I have spent hours researching this and I'm confidant that the Tiguan and RCD510 unit are OK - even the Bluetooth wiring harness tests OK - I borrowed the Bluetooth module from my daughters Skoda Yeti (5K0 035 730 E) and it worked fine in my Tiguan apart from it advertising it's bluetooth connection as SKODA-BT..

Maybe I need to get a different Bluetooth module version (although the F and E versions I have are both SW: 2902 and HW: H09)
Or some VCDS coding might be required..

Any advice/experience appreciated..
