Mystery stereo

[Ruffrida]

Hi all.

New to the site, so apologies if I am posting this in the wrong place.
I have had this stereo for while. Never used it. But whilst in quarantine I thought I would drag it out.
I have never had any wires (except the 1 you see).
Looking to see if anyone knows what it is. Or how to even power it up.
It look like a Valor but no stickers, numbers or name on it
Cheers in advance

With no markings, an ip-bus, and optical output, I think this is a secondary unit in an oem setup. Probably for the backseat passengers.

I thought that, but it has "band" etc on it, so thought not.
Whats an ip-bus?

Sorry just googled IP-bus. This could be for anything.
Would like to try and turn it on but don't what's what with the power lead.

Yes, I think it receives it's power and other signals via ip-bus. Pic below is an diagram of which I know not what most of it means. Good luck.
