Bluetooth Module Upgrade, coding might needed

Good morning everyone,

I have recently upgraded my existing OEM bluetooth module 5N0 035 730 D using a newer module 7P6 035 730 J.

Done this just to get the track info and skip feature. But it does not work. I can see the track info, I can skip the track, pause etc but have no soung at all.

After I play with the source switching between HDD and Bluetooth it goes back to not showing the track info like it did with the old module and have sound.

Might need coding I guess but I am not familiar with this other than basic stuff.

I can confim that is a Superb mk2 prefl with columbus navi mfd and steering wheel control.

Thanks !
