Ford Motor Co. this fall will offer an optional dealer-installed, hands-free phone system on three vehicle lines, amid growing concerns about distracted drivers. The technology, a docking station designed by Cellport Systems Inc. of Boulder, Colo., allows hand-held cell phones to be used hands-free with voice commands to activate the phone. The system uses the vehicle's audio system for responses. The system initially will be offered on the 2002 Ford Windstar and Taurus and Mercury Sable. In early 2002, it will be a factory-installed option on the Lincoln Continental and Town Car. By the middle of next year, the system will be available as a dealer-installed option for most Ford and Lincoln Mercury products, according to Kurt Kiser, North American manager for vehicle personalization at Ford. Future factory installations will depend on the success of sales, Kiser said.
