Looking at 2011 3/4 ton Dodge Ram Big Horn Edition/Cummins with a 430N Entertainment Center. I have been told by a few people that the My Gig Nav unit in my 2009 Dodge Ram may be inter-changed. My wife's 2011 Grand Cherokee has Nav and it looks like the exact head unit as whats in my truck.

Can anybody confirm???

I would like to swap and I think the dealer is ok with it if it will work....
