Digital Media Broadcast (DMB) Antenna

WARNING: This page is about a different car, the 2016 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.

The Digital Media Broadcast (DMB) antenna is located externally of the vehicle. The DMB antenna is used to provide traffic information, News information, and Points of Interest. The DMB antenna is powered through a coaxial cable from the Navigation Control module. Interference to the system may occur if signals are obstructed by atmospheric conditions, objects, tall buildings, and trees.
