A GPS navigation code device that enables a driver to retrieve directions, without taking his eyes off the road. The user pre-programs the GPS navigation code device with a plurality of addressees or points of interest, and assigns unique navigation codes for each as keyboard entry and speech, all stored in local database within the GPS. While driving, the user presses a special address search mode key and inputs the unique navigation code by keyboard or speech pattern, views displayed address and accepts the same. When an unknown navigation code is entered, the GPS accesses a remote database through the Internet to recover the associated company name and business GPS coordinates. The remote database computes travel distance based on vehicle and business GPS coordinates, creating an ordered list that is presented to the GPS user, together with directions by map and speech on a turn-by-turn basis.
