Adding (Activating) AUX input to 5.0L infotainment System

I want to utilize the Android Auto application through the Infotainment system installed in my 2013 XKR convertible. In order to do this I need to have the Auxiliary input activated. Jaguar dealers in NA cannot or will not do this. Does anybody on this forum have any recommendations as to how to accomplish this? Thank you.

From what I understand you have to have a very special engineering code from Jaguar to be able to do this. To the point most Jaguar dealers literally cannot do it.
