SYSTEM DESCRIPTION
1. DESCRIPTION
(a) Safety Connect performs ACN (Automatic Collision Notification), manual emergency calling and stolen vehicle tracking, roadside assistance services, by audio and data communications between the vehicle and call center through a cellular phone network. As shown in the illustration, when a collision is detected, the vehicle sends its location calculated based on GPS signals and the identification code of the DCM (Telematics Transceiver) to a call center. After the necessary information has been gathered, the call center will relay this information to emergency services.
