Circuit/System Description (Communication Interface Module)

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The communication interface module (CIM) receives information from a specific GPS antenna located on the outside of the vehicle. The GPS antenna is connected to the CIM via a shielded coaxial cable. The antenna cable also provides a path for DC current for powering the antenna.
