GPS, Easier to Update

I purchased a 2011 F350 King Ranch, and expected an up to date GPS. The GPS in the vehicle is so outdated and incomplete that Ford shouldn't be able to call it a "GPS" but a "sort of" or "close to" "Attempt at GPS". The "data" is almost 2 years old even though they keep repeating the update is from July 2010. Create an update that IS "up to date." Improve the interface, get some Ideas from users or even the competition.

The map updates really need to be some sort of free automatic service. (Wifi, phone, somehow.)
