I have a 2014 GT500 w. factory nav and shaker pro. Honestly the system sounds fine to me, but the UI is starting to look dated; and with the lack of support from Ford, I think going aftermarket is the way to go. Has anyone upgraded their head unit to a Pioneer or Kenwood unit with andriod auto? I can't seem to find a direct fit dash kit or anything to make this work. It appears the idatalink maestro will retain the factory on screen climate controls and such. So the only question is the dash kit and compatibility with the factory speakers, sub and amp.
