This isn't entirely accurate. The Navi AC system is controlled via the CAN bus. There is an AV CAN bus that interfaces with the Navi AC/Stereo control panel and communicates to the stock HU. The stock HU translates that communication into different CAN messages on the main CAN bus that connects to the HVAC Amp.
The non-Navi controls are also digital, but they communicate directly to the HVAC Amp via a dedicated serial interface (No CAN bus). There is no analog AC control in the Z.
One of the goals of my current project is to make this conversion a plug-n-play experience with the non-Navi controls interfacing with the CAN bus system.

Also, I have sourced the needed 10 position connector for the non-Navi control module locally from Mouser Electronics:
