How FMI Cables are used with Automotive Devices

Fleet Management Interface (FMI) cables are used to connect compatible Garmin devices to third party fleet management solution providers. Fleet management is the management of a company's vehicle fleet and allows multiple GPS receivers to communicate within the company. Some FMI cables support simultaneous lifetime traffic for North America and FMI data for their compatible devices.

A more comprehensive explanation of fleet management can be found  Garmin's Fleet Management Commercial Solutions

To view a list of which FMI cable(s) your device is compatible with, find your device's product page on www.garmin.com and select Accessories.
