Trucks have an SD card reader slot available in the center console area near the radio option. Slot size can vary for full or micro SD cards. You can locate it by looking for a card symbol on it. 

After starting the vehicle, and turn off the engine and insert the card to identify it. The card slot has an opening that will not allow the wrong insertion of the SD card.

Push the card by its label side facing the passenger seat. Once you hear a click sound, it means you have installed the card and secured it in its place.

After inserting the card, turn ON the ignition, and you will see instructions to install the navigation software. Follow them for a successful installation. 

After that, you will see a navigation option besides the entertainment on the MyFord touchscreen. It will take a few minutes for updated maps to install on your vehicle.
