Choose your poison. It hasn't been done and NEVER will be. When you ask why I will say because of all the wiring.
Then others will say that the OEM nav is garbage and that you should get an aftermarket unit anyways.
Alrighty then I gave the possible solutions. Mods lock this bitch up.
Good luck on your search for a new head unit OP!
