If your C6 didn't come with the navigation you can use these knobs for your factory radio too! Get two kits from us and you can do both the A/C and the radio!!

You will receive two Heater A/C Knobs with a chrome ring with this order.

Your 2005 did not come with these as the 2006 did; this is the time to enhance your interior!

Installation is a breeze! They just pull off, and push on the new ones.
