Although I got the Nav/Entune options, I really don't like the factory navigation. Today I "hardwired" my Garmin Nuvi, using a ProClip mount attached to the right upper a/c vent.
Using several of the build threads, I disassembled the dash and took out the head unit, ran USB wire through the a/c vent, behind the dash, up through the pop-out inside the glove box and plugged it into 12v outlet in the glovebox.
Took me a while - I've never taken a dash apart and the wonder of it is that I actually got it back together. Without too many scratches. :nod:
:whoo:
