Replace/reposition Nav climate controls

Looking to remove the Nav dash unit and retain the ability to control the fan and a/c .
I plan on keeping the housing (replacing with a tablet) and the lower controls just above the radio.

As you may already know...the navi screen controls the manual HVAC operations (fan, a/c: on-off and ventilation directions). in the non-navi model, those controls are handled by the analog dial that is nested in the same place of the dashboard that your current navi screen is located.

that being said, I think that it could be possible to replace that part of the dashboard with the manual controls, but not have both.

If you want to place a new aftermarket tablet, I believe most who've done this place a double din tablet right below the stock navi screen.

I think there were some at some point that were able to find a screen unit that allowed interfacing with the oem HVAC system, but I think the solution was rare, pricey and no longer available.

I'veseen this as mainly software issue as there is a touch screen.
Can't this be hacked?

Reverse engineering of the NAV A/C controls had been attempted years ago but I never saw any outcome that could be readily replicated without major time and expense like whitetiger mentioned.

A few options:

* Leave the Nav where it is and put the tablet where the radio is(not the greatest position for viewing or controlling while driving but the easiest if dead-set on a tablet)
* Move the Nav to the radio position(considerable work involved) and install tablet in the old Nav position.
* Delete the Nav and replace with non-nav A/C control head relocated to where the radio is(again, considerable work involved)
* Forget the tablet and install a Double din stereo unit with bluetooth, handsfree, Apple & Android connections, retain factory steering wheel radio controls, etc.

I went with option 4:
