Abstract
A method of installing a compass system includes the steps of mounting the electronic compass in a vehicle, coupling the electronic compass to a power source of the vehicle, downloading precalibration data into the electronic compass after the electronic compass has been mounted in the vehicle, and initiating a precalibration routine in the vehicle that is headed in a predetermined direction. The method may further include the steps of identifying characteristics of the vehicle and selecting precalibration data corresponding to the identified vehicle characteristics. The precalibration data selected corresponds to a make and model of the vehicle in which the compass may be installed and further may correspond to sets of vehicle options that may affect vehicular magnetism. If the electronic compass is provided as part of a trip computer, the precalibration data is preferably downloaded at the same time that the fuel tank size is downloaded into the trip computer.
