Hey court23 I will agree that the all-in-one unit is nice indeed. I am not sure where you can mount the Kenwood nav unit, I saw one person put it in the "cubby hole," but I wouldn't want to lose that space. I have far too much stuff in there (gum, emergency soda, sunglasses) to want to lose it. I am not sure where would be a good place to mount extemporaneous (xtemporaneous?) nav units and the like.
