Outside Temperature

The Compass/Temp Mirror utilizes vehicle speed and engine temperature data received on the PCI Bus to accurately display the outside temperature to avoid "hot soak" condition readings. The displayed outside temperature information is stored within the memory of the compass/temp mirror. When the Compass/Temp Mirror is first powered up, it retrieves the temperature data from the module memory. The memory temperature is compared with the temperature received from the ambient temperature sensor. The colder of the two temperatures is displayed.
