Hey, I seen you know the ins and outs of this vehicle's auto system pretty well. I have an 09' touring I just bought. It has the bose in it, with no factory nav. Im most likely going to buy the metra double-din kit, bose harness from crutchfield, and put in a pioneer 930bt. What kind of steering wheel controls would I need? and is this all I need to successfully switch out the bose system with this aftermarket HU or do I need more components?
