Popped over from the A4/B6 section - mate has just bought a A5 Sportback (2009) 3.0TDI Quattro and he is in need of a Bluetooth retrofit to accompany the Chorus 3 radio. Has any body got a part number or a VCDS scan showing info for the Telephone [77] unit like part number and software level, etc.

Have done this retrofit on my B6 a couple years back so know roughly what to do!!

Any advice greatly received.
