How standard are CD changer controls?

[Elder]

I'm considering going back to the CarPC project again now that CarTFT in
germany are stocking a double din Screen with AM/FM and a USB DVD rom
drive.

On the rear it has what appears to be a changer/remote control/line out
socket above the power/speaker sockets.

I'm waiting confirmation that the socket is actually present and
connected on the production models, but if it is, what changer could it
control if it is connected? never fitted a changer before and the car
isn't prewired even for re-speakers.

Plan is, fit screen and CD changer until the CarPC is built and then
have it returned to normal including the factory headunit when I'm done
but leave the changer in. The Skoda factory grundig appears to have the
same socket as the TFT screen/headunit.

There are pins present in the 3rd mini ISO connector, but it's by no
means a standard connector. The same pins may well be used in your
vehicle, but the voltages or signals present on the pins may vary
drastically from unit to unit. Philips, VDO, Grundig, Panasonic,
Blaupunkt and Clarion have all produced units with that style of
connector, but none of them are cross compatible AFAIK.

Thanks.
Nice simple answer.
Not wanted I wanted to hear, but better to know before I spend extra.
