First off this wasn't the only problem that went along with it but I put another one in here, anyway.. Every single day my navigation screen would restart, did not matter when. Nothing happened to it that would make it that way, I would be using it, driving down the road & boom, black screen, Nissan logo & it would have to do it's whole thing all over again. I went to go get the damn thing replaced (under warranty) & then just a couple months ago it still does it!! Either my dealership is a bunch of idiots or that's obviously not the problem.
