Why the TARDIS is always lost

Apple Maps will ensure that the TARDIS never gets lost.

There have been a lot of theories about why the Doctor cannot pilot (steer) the TARDIS with even fifty ten percent accurancy. Well, I now have a new theory for why the Doctor is never sure where he is going to materialize--Apple Maps. At some point in time, the Model 40 TARDIS designers decided to cut corners (we need no stinking map makers; we just need to plug in data), and installed Apple Maps as part of the standard TARDIS software package.
