what does tmc mean on volvo sat nav
Traffic message channel Traffic Message Channel (TMC) is a technology for delivering traffic and travel information to motor vehicle drivers. It is digitally coded using the ALERT C protocol into RDS Type 8A groups[1] carried via conventional FM radio broadcasts. It can also be transmitted on Digital Audio Broadcasting or satellite radio. TMC allows silent delivery of dynamic information suitable for reproduction or display in the user's language without interrupting audio broadcast services. Both public and commercial services are operational in many countries. When data is integrated directly into a navigation system, traffic information can be used in the system's route calculation.
Mazda CX-7 The CX-7 features fully independent suspension, four wheel ventilated disc brakes with standard anti-lock brakes, electronic stability control, and traction control, and a choice of either front-wheel drive, or Mazda's Active Torque-Split all-wheel drive system. With the Active Torque Split system, two computer controlled magnetic clutches feed up to 50% of the engine's torque to the rear wheels.
