The 12 OB we tested with NAV had the same exact NAV as the WRX I had from 2008! What? Seriously you haven't changed a thing in four years! Even ford has sync! Which still sucks compared to pioneer/alpine/clarion ect.
Bottom line DON'T get factory NAV get aftermarket for half the price. Unless your spending 50k on a BMW or Audi they are finally starting to get a clue!
