If you are buying it new, I belive that what you want is an option. I have a brand new 2006 Armada and to get the Sattlite radio I wanted I had to buy the $5,000 navigation system with the integrated sattelite. SInce I know how to read a map I bought a portable which is really cool because you can take it with you, buy a booom box adapter and it is less than $100 bucks
