Can you buy a stock navigation system from on vetteand put in vette that didnt come with one? and would it still have 6 disc changer on dash?anyone tried this or would it look better with aftermarket one....

 

You could have that done, but there would be lots of money involved in labor in addition to the $1000-1200 for the navigation system. I personally wouldn't recommend it, but that is up to you. My C6 had navigation, but the previous owner put in a custom Eclipse touchscreen navigation system instead - it is nice!

If you need a navigation system, just buy a portable one that you stick on the dash. They only cost $300-400 and do the same thing.
