I wonder if those who opted out of the Navi got a good demo at their dealer? I got a demo that underscored everything you folks said. Once I saw it I knew that was a 'toy' I wanted!
My wife would be a passenger mostly in the X, so that seat does not require frequent adjustments, Bose never has impressed me, and I have a $300 (installed) Pioneer 12 disc changer under the passenger seat of our present minivan that sounds excellent even playing through FM, have had 2 cars with lots of cargo room so never needed the roof racks they came with (and can always add one later myself), and considering a back up warning system (self-install), so much for the 'dipping mirror' , and as primary driver, the memory seating is wasted on me.
Half the $2600 will buy me nice side steps, rear mud flaps, BSM, cargo net, and upgraded HD mats for the seating and cargo areas. The other half will help pay for nice vacation down the California coast. oh, sorry, Marne, and a visit to a members vineyard in Sonoma.
