Navigation Systems Available Here!

The following are instructions on how to install a factory navigation system into a GM Lambda platform crossover vehilce. These vehicles include the Buick Enclave, GMC Acadia, and the Saturn Outlook. In this example we installed the navigation system into a 2008 Saturn Outlook that did not have the navigation option from the factory.

In order to install the navigation unit you will need the unit itself, the navigation antenna, and the navigation map DVD. In this particular case we used a GM navigation unit which was OEM part number 25816282 with a GM antenna which was OEM part number 15255334. Below are the steps necessary to install this OEM navigation system into a vehicle that did not originally have one.

Step 1:

Remove the two ten millimeter bolts that hold the oh sh#% handle on. Remove the handle. Next remove the A-pillar trim panel. The trim panel snaps on with a couple clips. You will also need to unplug the tweeter mounted to the trim panel.

Step 2:

Remove the A-pillar trim on the drivers side. You will need to remove a seven millimeter bolt located underneath a small plastic cap. This trim panel also clips in with a couple clips. Again you will have to unplug the tweater mounted in the panel.

Step 3:

Remove the dash trim panel that buts up against the windshield. This part clips on, there are no bolts to attach it. Be careful as the part is made of plastic. You will have to disconnect the light sensor that is connected to this trim panel. To disconnect it just turn the sensor counter clockwise and it will come out.

Step 4:

Next remove the trim plate around the radio and the upper console in the center of the dash. Both of these parts are clipped on. You will not need to remove any bolts or nuts to remove these panels. You will have to disconnect the wires for the heater controls.

Step 5:

Now you will need to fish the navigation antenna through the dash. In this case I used a coat hander and bent it into shape where I could insert it through the holes in the dash. I used electrical tape to fasten the navigation antenna to the coat hanger. I pulled the the antenna through the first section of dash as pictured above. I then removed the antenna from the hanger and fished the hanger into the lower section of the dash. I then taped the antenna up and fished it the rest of the way through.

Step 6:

Snap the antenna into place. There is a place for the antenna to go directly underneath the first trim panel that was removed from the dash on the passenger side.

Step 7:

Make sure to run the antenna wire into the lower openings in the dash where the rest of the wires for the radio come out to make sure that the nav antenna wire does not get pinched.

Step 8:

Re-assemble. It is always good practice to plug everything in and test it before you completely reassemble the dash. Make sure everything works properly.

Step 9:

If everything works properly you should be up and running at this point! When the unit first turns on you will be greeted with the “Delphi” screen / logo. The nav will need a navigation map disk to function as a navigating system but you will be able to use the the radio and all of the other features of the navigation unit. The map disk is inserted behind the screen of the navigation system. The screen folds down and the navigation disk is inserted. This allows you to use the other visible drive on the system for CD’s, MP3 disks and even DVD movies (which can only be viewed while in park). You will also want to disable the rear camera option (since your vehicle did not come with navigation it also did not come with a rear camera) or else you will get an error message about your rear video system. To do this go to “menu”, click “display”, choose “rear camera options” and uncheck the box to view rear camera while in reverse. This will eliminate the error message and your nav system will remain the same when you shift into reverse.

So there you have it. How to install a factory navigation system into your Buick Enclave, GMC Acadia or Saturn Outlook when it did not come with the navigation system from the factory!
