V36 2008 Coupe Wiring Differences with Android Screen

[sausagepianist]

Hey all, I'm sorry if this has been discussed before.  I have a 2008 Japanese import V36 coupe with nav but without Bose.

I bought one of those AliExpress android screens, which for the most part works really well.  The only thing that doesn't work is the air con controls (well sort of) and the factory reverse camera.  The AC can be controlled fine but it doesn't report the change in temp and mode to the screen, and the volume knob/other audio controls from the panel don't register on the learning app. 

I am pretty certain that the problem is the difference in the head unit between base model (Nav but no Bose) 2007-2009 coupes and anything after 2009.  Mine is the one with the blue connector all the way to the right as seen in this forum post: 

The reason I think this is there is one wire left over that doesn't fit anywhere on this head unit, or in the factory screen which also uses different connectors to more recent versions.  I've seen the upgrade from OWC, and have sent the guy a message on eBay but no response yet.  I also don't particularly need the whole kit, just *maybe* an adapter for this one cable. 

Did anyone else here have the same problem, or have any insight about what I can do to get this working?  I have been in contact with the seller but all they seem to be able to do is ask for more pictures and videos.

Minor edit to add:  I have been researching and found a screen on Aliexpress that actually specifies my head unit in the listing, so these things do exist.  I will contact the seller to see if the wiring adapters are interchangeable with other screens.

 

Thanks in advance!

It doesn't really answer your question...but is the head unit full android or just android auto, are you happy with how quickly it boots and responds, and do you have a link?  If we can identify good Android alternatives it will really help people stuck with Japanese screens.

Did it have a separate reverse camera input so you would replace the factory one, or are you just going without now...that would be a pretty big steps back.

And finally, do you have a picture of the "wire" that you can't plug in? Most likely it is some sort of aerial that is not too important eg japanese traffic or am radio or something if you haven't noticed a functionality issue
