Navigation System
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 hard-drive. The ACM calculates route information based on GPS data. 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 shown on the FDIM. Either the FDIM touchscreen or the buttons on the FCIM can be used to interact with the navigation system.
The compass heading is derived from the GPS antenna signal. There are no serviceable parts for the compass.
A voice recognition system allows the user to interface with the system without using the touchscreen. A microphone located in the auto-dimming interior mirror provides the voice recognition input. The microphone is shared with the SYNC system.
Information and Entertainment System
Functional Components
The functional components of the audio system are:
Audio Control Module (ACM)
Front Controls Interface Module (FCIM)
Front Display Interface Module (FDIM)
Accessory Protocol Interface Module (APIM)
Audio amplifier, located in the RH side of the luggage compartment (vehicles with navigation)
Global Positioning System Module (GPSM), located in the instrument panel (vehicles with the SYNC system but without navigation)
AM/FM antenna, located on the right rear quarter panel
Satellite radio antenna, located on the luggage compartment lid
Global Positioning System (GPS) antenna, integral to the satellite radio antenna (vehicles with navigation)
AM/FM antenna cable (must be overlaid on the harness)
Satellite radio antenna cable (must be overlaid on the harness)
Universal Serial Bus (USB) port and cable, located on the inside front of the floor console stowage bin
Audio input jack, located on the inside front of the floor console stowage bin
Clockspring
Auto-dimming interior mirror (contains the microphone)
Satellite Radio
The satellite radio system is comprised of the following:
Satellite radio receiver built-in to the ACM
Stand-alone satellite radio antenna (vehicles without navigation)
Combination satellite radio/GPS antenna (vehicles with navigation)
Satellite radio antenna cables
The satellite radio antenna cables connect the satellite radio antenna to the ACM. The satellite radio antenna cables are not removable from the wiring harness.
The external antenna for my Sat Radio is centered on the trunk lid. I would imagine it would/could incorporate, if not use, that same antenna for the stock GPS. Do you need a picture of it?
Yup, that helps... Thanks... It is infact one unit. I just cross referenced it on Tousleyfordparts it is one in the same!!! Damn it.. looks like I will be buying another... lol
