Original BMW Stereo Install

[IamStandingBehindYou]

I picked up an original BMW Stereo to swap out the dodgy aftermarket unit that the PO had installed, I've hit a wall now because I need a plug for the BMW stereo and I can't find it anywhere. I'm not even really sure what to look for to be honest.

I've included pictures of the front and back of the head unit, does anyone know the part number or where I could go to find it?

Thanks for your time!

Speaker plugs are standard 'DIN' two pin 'speaker plugs, although you may have to discard their outer covers.
It looks like individual 'lucar' terminals could be used for the other connections.
