Swapping Aircon controllers - is it possible?

[jvoelcker]

I'm swapping over the central caddy on D3's A3 to give a double DIN at the top to fit a Carplay kit.

The replacement caddy has a slightly different button setup to the original - on the left the there is a ECON button on the original and on the replacement there is an AC button - will the buttons work as originally intended or as per the writing on them?

Will I need to do some coding to get the new one to work?

There are photos of the two at...

There may also be wiring differences, you need to study the diagrams for both.

To be expected I guess
