I'm considering pulling out the factory NAV system in my '04 XJ8 and replacing it with a 2 DIN aftermarket product.

Since the climate control is integrated into the NAV Dash Head, I'm wondering if it's easy enough to buy a used standard climate control module and retrofitting that.

Question is: does anybody know if the wiring harness for the NAV system has an independent plug for the climate control functions that would be the same for a standard climate control (Jaguar XJ8 X350 04 09 XJ Climate Control Unit Panel 2W93 18C612 Ad | eBay Or am I getting into trouble here?

Consult workshop manual in detail, especially electrical guides for multiple models, but I'm doubtful.

 

From the electrical guide, they are not directly compatible. The Nav systems control the climate module via the CAN bus, where the non-nav models are using standard signal wiring directly to the module (see Fig 6.1 in the electrical guide).

That said--from my experience Jaguar does not have separate parts for these cars. My guess is that you could probably get the climate harness from a non-nav vehicle and connect the standard climate control panel to it. However, you may need to reconfigure the CC module with SDD/IDS to tell it that the Nav setup is gone..

EDIT: from the thread on this same topic in May, you need to change the climate control module to one that has the connector for the standard control panel. See posts #11 and #12 here: https://www.jaguarforums.com/forum/x...0/#post1238416
