Has anyone seen the Nav in the Lexus'? I was at the NY Auto Show and was checking out the Nav in the LX450 (the Land Cruiser copy) and it was FAR superior to the X's. The lines on the map were actually in a 3D type of display, and the screen was touch sensitive for positioning the crosshairs. Whats the likelyhood that we might see some better graphics out of a newer release?
