How to Use the GM NAV System

By Nick Miles

An in-car navigation system is a useful tool that gives you turn-by-turn driving directions to a given destination. Most GM vehicles offer a navigation system as a standard feature or as an available option. Learning to use the navigation system can save you time and will get you to where you are going without getting lost.

Step 1

Place the vehicle in "Park." You cannot operate the address-input functionality of the navigation system while the vehicle is in motion.

Step 2

Press the "Power" button to turn on the Infotainment System if it is not already on.

Step 3

Press the "NAV" button on the center console to enter the navigation menu of the Infotainment System.

Step 4

Press the "DEST" button to open the destination entry menu.

Step 5

Use the selection arrow keys to select the state of your destination. By default, the state will be set to your current state, so you will not have to change this if you are driving locally. Press the "Select" key to make your selection.

Step 6

Use the selection arrow keys to input the street name of your destination.

Step 7

Use the selection arrow keys to input a city name or select one from the list.

Step 8

Use the selection arrow keys to input the house number for your destination.

Step 9

Press the "Go" key to begin route guidance. The system will calculate the best route to your destination and give you directions on how to get there.

Step 10

Press the "NAV" button to cycle through different map views. You can choose between full map view or audio/map split view, which splits the screen between the vehicle's audio system information and the navigation map.
