A portable computer terminal is disclosed which may operate in a hand-held mode and while docked within a vehicle. The terminal interacts with an illumination means therein which can be used for bar code reading and, while docked, for providing illumination for a head up display on the vehicle's windshield. Textual messages undergo text to voice conversion as well as head up display. Moreover, to provide full hands-off operation, voice recognition of predefined sets of commands is incorporated within the terminal. In another embodiment, the illumination means is placed in a housing separate from the terminal. A wireless link between the illumination means and the terminal provide for communicating text and graphics for head up display.
