Abstract
In-vehicle operation of a wireless communication system handset is enhanced by using a handset controller having large keys and a large display. The controller is mounted in the vehicle so that the keys and the display are accessible by a user while seated in the vehicle driver's seat. The keys and display are backlighted to improve visibility. The controller warns the user in the motor vehicle that the handset is disconnected from the controller. The controller accepts verbal commands to operate the handset and outputs messages received by the handset and other information associated with handset operation as synthesized speech.
