I put this in my wife's car about a year ago and at first I was very impressed with all of the features (similar to my oldschool pioner premier DEH-900R), but one feature that is missing from the new head unit is the sound mode for "club, jazz, studio, ect..) However the newer unit has the ability to self optimize with an external microphone that you can attach to the drivers headrest(I've yet to use this option, but its cool).
One major gripe I have with this product is that the faceplate often loses connection with the backplate, so the volume knob doesn't work, or none of the buttons work, or sometimes on startup, the front display doesn't light up and none of the buttons work (you can either live with no radio or restart the car). Sometimes if the unit has stopped working after startup you can jiggle or press the faceplate and it will start working again.
Other than that it has been pretty trouble free, and gives excellent sound quality and adjustability.
