I just installed the Clarion N.I.C.E. Navigation System in my Armada using the factory navigational dash trim. I love the N.I.C.E. unit so far and I'm thinking about ordering the Sirius module that goes with it. I want to add some pics of the results, but I'm over my quota. It's just what I have been looking for. Crutchfield sells the N.I.C.E. unit for $1399, but I found it at www.hookedontronics.com for $887 and the dealership gave me the factory housing for $146. I'll aslo be ordering a leather package for The Beast as soon as they call me back.
