How to Update the GPS Program in a 2008 GMC Yukon

Many GMC vehicles, such as the 2008 Yukon, can be equipped with additional features, including a GPS navigation system. The navigation system is designed to assist drivers with turn-by-turn directions that follow the fastest and shortest routes available. Navigation updates are released annually for GMC vehicles. After purchasing an update from the GM Navigation Disc Center, it is mailed to you on a DVD. The update can then be installed on the navigation system.

Things You'll Need

• GM Navigation Update DVD

Instructions

1. Purchase a navigation update from the GM Navigation Disc Center, if you do not yet have one (see Resources).

2. Start the Yukon's engine, and wait for the radio to come on. Press the Navigation Radio's "Power" button. Place the screen in full-screen mode by adjusting it with the "Navi screen up/down" button.

3. Insert the navigation update disc into the system and wait for the update confirmation screen to display. Press "Update" and enter the code provided on the update disc's case.

4. Remove the disc from the system when the "Completed" message is displayed. The update process may take up to 3 hours.

Tips & Warnings

• Do not turn off the car, disconnect the battery or eject the disc during the update process. These actions can permanently damage the navigation system.
