Actually, unless something finally came out from one of the interface companies I called directly to check on a unit that would work on the 2014, we are stuck as well, nothing made to allow us to change the HU or I would of done in nearly two years ago after the first time I used and cussed out the factory NAV.
I do not even want NAV now, just a great DD unit I can make fit, my phone is a great navigator.
