Called Avis Assist, it allows renters to receive spoken turn-by-turn directions to their destinations on a GPS-enabled Motorola mobile handset, which is fitted with a speakerphone.
The service is continuously updated with map data and is integrated with point-of-interest databases to provide users with the most accurate and up-to-date navigation services possible.
Via speed dialing, the customer connects with the call center and provides an Avis advisor with details of their required destination. A route is then downloaded to the Avis Assist unit, the Motorola handset, and turn-by-turn directions are provided.
The companies will extend the service to Washington's Dulles airport.
Scott Deaver, executive vice president of marketing for Avis said: 'Avis is committed to providing technologically advanced products that exceed our customers' expectations. Motorola and the other partners have developed a portable navigation system that gives our customers a system they can enjoy in whatever vehicle they choose to rent.'
