100% fed up this evening.
no ones fault obviously and i value everyones advice to date.
I bought 2 bluetooth kits 7P6 035 730 M (one to upgrade the van and one to install in the car). I was hoping the M module, compared to my current J version, would give me the track info on the head unit as I've wanted all along.
Sadly this hasn't solved things. I tried simply changing the J module in my van for the M module in the van and also tried with the new loom and the M module in my car.
Both worked exactly as my current J version.. IE.. perfectly well as a handsfree kit and to stream audio but without giving the track info on the head unit and without giving control of the music to the head unit or the steering control..
Any other ideas?
To recap..
I have an iPhone 6 (I also tested my J module with a friends samsung S4 mini)
2012 VW Caddy highline with RCD 510 DAB currently with 7P6 035 730 J
2005 VW Golf GTi with RCD 510 DAB. currently no Bluetooth but now tested with 7P6 035 730 M and not giving track info.
Everything works perfectly, just no track info or music control when playing bluetooth music either in napster or iTunes on the phone.
