Planning on upgrading my headunit. There are plugs on the back of the existing head - power/speakers, antenna, and a 16 pin port that seems to talk to the can-bus, and provide things like aux-in.

I'm having a heck of a time trying to figure out what that port's actually used for (and more importantly, is it one I need to pay attention to?).

I think it's where the aux and usb route through.

Is there a pinout for it? Can't find the receptacle harness (SKMA16-11?). Should I ignore it?

thx
Liam
