And here is the DIY proof. I have just made a video for you.

Hell's teeth. It works. Bugger me. Thank you. I'm sitting here with
the radio in my hand.

Next scary bit is the wiring. There are two 8 way connectors in the
back of this radio, but the one on Amazon only has one 6 way connector,
but there must be a way of joining the two. Probably.
