Navigation System

WARNING: This page is about a different variant/trim than selected.

The vehicle navigation system guides the user to a pre-entered destination. No navigation map DVD is needed, as the map guidance information is stored in the ACM. The ACM calculates route information based on Global Positioning System (GPS) data. The GPS antenna tracks several satellites simultaneously. The ACM also uses vehicle speed and transmission gear selected signals received through the MS-CAN to detect vehicle speed and direction, resulting in more accurate navigation tracking.

The navigation display is part of the ACM. Either the touchscreen or the buttons on the ACM can be used to interact with the navigation system.

The compass heading on the ACM display is derived from the GPS antenna signal. There are no serviceable parts for the compass. If the vehicle is equipped with an overhead console, the compass display in the overhead console is derived from the compass module built-in to the overhead console.

A voice recognition system allows the user to interface with the system without using the touchscreen. A microphone located in the interior rear view mirror provides a direct input to the ACM. The microphone is shared with the SYNC® system, if equipped.
