Chevy Traverse Audio Question 10 points?

Recently I purchased a 2011 Chevy Traverse. Silly me I opted for the dual sun roof instead of the Bose audio system. Having Bose in my Denali I didn't think there would be a huge difference. Boy was I wrong. My question is, is there a way I can go to the dealer and have them install the factory Bose system and speakers that comes standard on the 2lt models.
