Chorus 3 - 30-pin iPod Dock to Lightning adaptor

[Scooby]

Hello again

This is connected to my other post, but is a very specific issue I'm hoping to get an answer for. If anyone here has a Chorus 3 head in their circa-2009 Audi which has a factory-fitted iPod dock in the glovebox, have they tried fitting an adaptor to this (30-pin to Lightning 8-pin) in order to connect their newer iPhone to the system?

If so, did it work? If so, how well eg: what radio/steering-wheel control did the Dock have, and has that changed using the Lightning?

Many thanks.
