Honda Alpine satnav pinouts

I have just bought a s/h Honda/Alpine satnav unit, the 2 DIN slot DVD
version as used on 2003 Civic etc.

Can anyone let me know what the 4 connectors are for and does anyone
have the pinouts or schematics of these as I need to wire this in to a
non Honda car.

The 4 connectors are:
1x 20 pin rectangular black socket with the outer 8 pins larger than
the rest, at bottom of the back
1 x 14 pin rectangular white socket just to the left of the 20 pin
1 x 12 pin rectangular black socket on top RHS of back
1 x 7 pin (on a single line) rectangular green socket

Does anyone know where I can get the plugs for these too.

Thanks

 

Have you got the Alpine model number, or even better the Alpine serial
number?

 

Part number is 39541-S9A-G510-M1
Serial number: FEB22008995

 

I'll see my mate later this week, he knows about these things, I'll let
you know if I get anything

 

Thanks, appreciate it.
