I been searching all over for XM radio or Sirius radio, this 2 are the satellite options for my 2008 Chevrolet Silverado, this option was available at the dealer for $400.00 but I decline, because I didn't what it was now 5 years later the regular fm radio is bad so I been to 4 shops and 3 dealers they all say not possible, but I was told from oemautosound.com that this was possible with a simple kit antenna and wiring harness they will make for me a week later I have Sirius satellite that shows up in my original Chevy radio, no units in the dash or lose cables in the air , all of it is behind the radio, I will recommend oemautosound to all my friends
