I AM getting ready to purchase a D3. I have a 2007 Denali Envoy, according to Crutchfield it says that it wont fit. Dont understand that one. Also I was wondering if headrest monitors can be hooked to the D3 because it doesnt have a seperate brain right?

It will fit, cause the Envoy is a double-din, and there is a video out on the D3 for external monitors

Actually it isn't a double din. It's a weird shape. The dash kit is what allows the weird shape to be converted to a double din.

do you mean b/c of the rounded corners?, ah you mean "true" factory double-din... WITH a kit it is double -din

do you think you could direct me in the direction of a kit for it??? thank guys

Thanks for the link I really appericate it. Im still trying to get rid of my other N2 that is a refurb from pioneer, i bought 2 off ebay and never installed this one. So as soon as this one sells, im going to get a D3
