Ford Navigation System

My idea is for Ford to come intothe 21st Century. Ford Needs to allow the Navigation System to be upgradeable. The Point to Point system has been outdated for 10 - 15 years nor but Ford put these in the new Fords. Then they will not allow you to upgrade them.  Ford needs to Nav. system with maps. A $49.00 Garmin gps is better then what Ford has right now. My Idea is for Ford to allow the User to upgrade the Nav. System in the Car
