2008 GM Full Size Truck Navigation Owners Manual Original Supplement

This factory-published original manual shows you how to operate your navigation system. You will find a symbol glossary, which will identify each button or symbol, virtual or physical, with an image, and explain its function. You will learn to program your destination and detours using step-by-step instructions accompanied by images of each menu that should appear on the screen. You can also learn how to use the interface to operate connected equipment such as air conditioning controls or the audio system. Factory-produced navigation systems use proprietary hardware and software that is not typically user friendly. Buy now before you pull the rest of your hair out trying to program that thing!
