Hi
Recently bought a 2004 A4 Avant SE. It had the Audi concert head unit.
I didn’t know but found I could connect via Bluetooth to answer phone calls. There’s also another device showing on BT on my phone as “Headset”. When I click to connect it says Dab connected?? No idea what that means?

Although phone calls work, is there a way to play music from my phone?

Thanks
Andy
