as time wears on, I'm just lovin' my x920BT more and more every day. For what I paid (sub $400), this has been the best tech purchase I've made in a long time. Sure, the nav could be a little more slick, and the BT quality has some up in arms (mine seems to be mostly fine), but overall, this is a great machine that has made my driving experience better every day.
I'll keep hammering Pioneer for improvements, but overall, this has been a great purchase.
I even find the ECO thing mildly amusing, especially the submarine "ping" that goes off when I goose the throttle.
