2010 Peugeot 3008 - R45 Radio

[ianthomp63]

So, I've had a lot of issues with the android radio that was installed in my 2010 3008. So I decided to put a R45 radio back into the car, I've sourced a unit and found someone who can update the VIN in the radio. My next issue is the MFD screen, does the connection for this come from connections on the radio or a separate cable from somewhere else. I ask as I can't locate a cable behind the dash. Help appreciated

The RD45 pinout is here: viewtopic.php?p=725917#p725917, and the RD4 is in the following post.

I think that the head unit communicates with the display via the can bus, so no extra connections at the head unit.
