Hello

I have a 2008 Mazda 5 with sat nav and I have just bought a used 2007 Mazda 5 rear entertainment DVD player for it.

I now have this installed and running (on headphones) but I am struggling to sort out the audio connection to the sat nav head unit (its the all in one with 6 CD ROMs and a map DVD) as aux 2. It should be simple audio L & R plus ground and a activation signal but there seems to be no wiring diagram published and as the iPlayer/iPhone already uses the standard 16 way Mazda input for aux 1 I am not sure of the wiring. I believe it uses the 10 way socket (8 pins fitted) next to the 16 way but I cannot get it running yet.

Any leads would be appreciated please.
