that rotary-push-joystick knob is the dumbest thing Pioneer ever put out. I've used it in my friends' cars and it makes me want to grab the headunit and toss it out the window everytime If you like Pioneer, get the $219 one even though the pre-outs are only 2V. I had a DEH-P850 for 2 years and a 6500 for 2 years before that. Happy with Pioneer so far.
