Downgrade from touchscreen to standard HVAC/radio setup
#1
![Question](https://www.jaguarforums.com/forum/images/icons/icon5.gif)
Hi there.
I recently acquired a 2006 XJ Vanden Plas with the navigation/touchscreen head unit. It's really dated, and I would actually prefer to downgrade to the standard separate HVAC, then do something different for a head unit (and yes, I have heard of JagDroid).
What do I need to do for this? I'm prepared to gut the whole sound system and will likely do so anyway, but are there any other considerations I need to take before downgrading to the standard, non-touch HVAC system and then installing an aftermarket head unit?

It's possible, in theory. You would have to get the base model climate control panel, and the corresponding HVAC controller. The nav systems are different, they use the CAN bus to communicate between the touch screen and HVAC controller. The base models have a direct connection between the panel and the controller. There have been threads on this in the past and I recall the two controllers are different (e.g. one controller does not have both connectors for base and nav system). You'd also have to deal with the CAN bus connections at the nav module if you're removing that.
I think the big challenge is going to be reconfiguring the car to use the base HVAC vs Nav system. I'm not sure the details on what needs to be reflashed or reconfigured, but you'll need SDD.

I'd love to do this too. Does the VDP have the 'auxiliary' A/C for the back seat?
If you have the lousy pop-open cup holders, instead of the nice armrest-slides-back console, you've got a secondary A/C and I'm not sure if it will work without the Nav head unit. Maybe it would still work independently with the physical control panel?

Maybe I'll go with a JagDroid after all; it's just that I don't have the patience to do the electronics work, and I can't get the guys there to respond to an email or Facebook request.

Does something within your unit, not function? The sound system has enty of bass and is actually decent for a factory setup, once one figures out MODE = AUDIO....lol. Most manufacturers have made it increasingly complicated to do a weekend morning swap/upgrade. Technology, while simplifying life's functions, drastically complicates the process to get there. I prefer KISS. Get a fm modulator, 10 min and costs less than a dinner tip. JM2C
