DAB and Android Auto

[AndyHH]

Had an Audi for nearly 19 years now.  Originally a brand new tax free A3 new shape in 2004 (I was in the RAF in Germany).  part ex'd that for an A4 and them got an A6 Avant in 2016.  Recently sold that and got a 19 plate Audi A6 Avant and love it.

The 19 plate has been into the dealer for work on fixing a rattle in the dash and they gave me a 21 plate A6 Avant as a courtesy car, had it for over a week as they cracked one of the screens and had to replace.

The 21 plate had wireless Android Auto and on the DAB all the stations had the relevant icon to accompany the station.

In my 19 plate, I have Android Auto it isn't wireless and needs a cable and also the DAB stations do not have the station logo just a generic radio DAB icon.

Is his just the 21 plate being newer or is there something I can do or am doing wrong?

Thanks in advance.
