Optional on Denalis and Escallades, not available on Suburban. I would love to add it to my LTZ, but i hear wiring must be done, only question is do i need a new clock spring also??
If you look the heated wheel has a button on the left side, it splits the cruise cancel button in half like the right side where the radio controls are.
Search on ebay for one, they are sold all the time so you can get a pic of one.
