The Uconnect 8.4 RA3 unit does not have navigation stock but for $600 (which I thought was steep but paid for it anyway) the dealer can activate the navigation functionality. It has about 99% of the full functionality of the RA4 head unit but it is nice and works great. I also like how when a turn is coming up the truck also displays it on the screen in the gauge console. It's not well advertised because the only way I found out navigation could be added was by a little note in the truck's package description. "GPS capable, ask dealer for details"
