Anyone know how to retrofit the latest head units with touch pad into a 2013 x3 with the current predecessor to the latest units? Can it be done?

from what i learn with bmw vehicles any retrofit is expensive and im sure it can be done once parts are available online. i use getbmwparts.com. removing dash board wont be easy theres alot of wires behind it and other elec. components.

well isnt it just removing the combox and the touch pad?

The touch/non-touch controller speak on different buses: the non-touch uses a low-speed bus and the touch version uses the body electronics high-speed bus. They are incompatible and cannot be easily retrofitted without ripping up your wire harness and (possibly) swapping the ZGW too.
