It wasn't a goof, but a choice.. either the Shaker 1000 or the Nav - 'cause you can't have your cake and eat it too. Went with the Nav

 

My goof was not getting the 3.55's, but it actually worked out better because I might have never put in the incredible 4.10's.

 

+4 but I love the car and don't really care. Mine was on the lot and I did not have a chioce. ItHas the comfort group, Satin IUP.

I have seen other CS ordered without IUP. Are you installing those IUP parts from the for sale thread?
