I have 2006 Super Duty King Ranch and it has less than 8000 miles on it now, so I do not want to trade it off, but I would like to upgrade my system to the new OEM NAV sytem and maybe also add the sat radio while I am at it. Those were items that in 2006 were not available. The bases of the Cab are the same and both the 08' and 06' head units look about the same size. Anyone have any thoughts as to rather this upgrade is possable .
