Thanks for that Steve. I expect there are also android versions of the kit that you bought. I'll look into that. By the way, does the box live in the centre console?
I might yet buy a later model that I believe would give me the audio input and forego the complete connection that you have achieved. It will depend on what is available at the time.
I remain a bit surprised that these initially very expensive cars are not better equipped in this area for the model years involved 😕
