Joe, you are a star. I didn't even realise that my (old) iPod has bluetooth, because hitherto I've always connected to every VW with a USB > lightning cable.

I switched on Bluetooth on the iPod then went out and sat in the car (with engine on, obvs) and pressed various things on the less-than-intuitive display. They paired with each other, with the usual agonising wait (will it? won't it) and then dismissively told me that it couldn't find any tracks.

Sitting there looking at the user manual, I became aware of faint music playing.
I turned the volume up with the button on the l/h side of steering wheel.
It was my music!
But a random track.
OK we have a connection.....
Then, eventually, and almost as if it, the VW, had deigned or condescended to allow me access to my tracks, a display appeared on the screen on the track playing.
I could move to next track with a button on the r/h side of steering wheel.

However, I can't find a way of selecting 'Artists', it's the entire playlist in either random or alphabetical order, but that is better than nothing.

THANK YOU.
