* Automatic dimming rearview mirror: This is the most common. It uses a sensor to automatically adjust its brightness based on the headlights of cars behind you.
* FordPass Connect module (or similar telematics module): This module provides features like Wi-Fi hotspot, remote start, and vehicle tracking. Its placement varies, but it's sometimes found near the rearview mirror.
* Integrated garage door opener: Some models integrate a garage door opener into the rearview mirror assembly.
* Sensors for driver-assistance features: Features like lane-keeping assist or adaptive cruise control might have sensors located in this area, though they are not necessarily visible.
To know for sure what device is in *your* Ford Expedition, you should:
* Check your owner's manual: This is the best place to find a diagram of your vehicle's features and their locations.
* Look closely at the device itself: There might be markings or logos that identify it.
* Consult the Ford website: Their website might have diagrams or specifications for your specific year and model.
Without knowing the specific year and model of your Expedition, it's impossible to say definitively what's under the rearview mirror.
