Cellular and GPS/Glonass Antennas

WARNING: This page is about a different car, the 2018 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.

The antenna will have any of the following functions when equipped with ERA Glonass:

The ERA Glonass system uses the input and output cellular antenna elements to send and receive cellular data. The cellular signal is carried by a coax cable that connects the antenna directly to the telematics communication interface control module.

The GPS/Glonass antenna element is used to collect the signals of the orbiting satellites. The GPS/Glonass signal is carried by a coax cable that connects directly to the telematics communication interface control module.
