i would look around and try to find another place sounds like their trying to rip you off their

 

Go to Onlinecarstereo.com They have the best prices cause they sell wholesale. Excellent customer service if you call to. Best of luck. I went with a double din radio to get rid of the "dog ears" on the stock dash. It eliminates the small tray under radio as well. You just have to find a dash trim piece from a truck that has a factory nav package. Junk yards are best.
