Modular Expandable Mobile Navigation Device
First Claim
1. A handheld modular mobile navigation device, comprising:
- a base unit housing including a bus, a processing component coupled with the bus for determining a geographic location of the navigation device, a display screen coupled with the bus for presenting information related to the determined geographic location, a power supply coupled with the bus, a receiver coupled with the bus for capturing signals utilized by the processing component in making the geographic location determination, and a primary connector coupled with the bus; and
a module unit housing configured for releasable attachment directly with the base unit housing, the module unit housing including a mating secondary connector for interconnecting with the primary connector of the base unit housing and a circuitry component coupled with the secondary connector for performing a dedicated function resulting in associated signals being relayed through the secondary connector to the primary connector and onto the bus of the base unit housing when the module unit housing is releasably attached directly with the base housing unit.

Abstract
An expandable system for mobile navigation facilitates a modular implementation of structural units to add desired functionality to a base navigation device. The system is embodied as a handheld mobile navigation device in one arrangement, including a base unit housing containing circuitry for determining a geographic location of the navigation device and a module unit housing containing circuitry for delivering additional functional activity. In particular, the base unit housing includes a primary interface for interconnecting with a secondary interface of the module unit housing, to enable signals generated or handled by a circuitry component of the module unit to be relayed to the circuitry of the base unit housing. Additionally, the module unit housing is configured to be releasably attached directly with the base unit housing upon the primary interface and secondary interface interconnecting with one another, to form the mobile navigation device as a physically connected package.
