Put this in my 2008 Wrangler and was very very happy how it made a huge difference in the stock speakers. The USB port is a great way to go and helps keep the car free of floating cd's. I later added some Infinity speakers up front and Polk Audio speakers in the roll bar and the sound is fantastic. This is well worth the money and has actuall converted me from Kenwood to Pioneer
Just purchased it and design looks great, its a little tricky to figure out how to navigate with the selector knob and there are no preset buttons for radio stations but once you get used to it, its easy. Has excellent feel and quality to it. Had a factory radio that did not have an aux output and needed a modern head unit, this fits the bill, can play USB, MP3, IPOD, and CD-RW which is great can Store lots of MP3's on it and then with their playback system it will enhance the MP3's to sound like CD quality, Excellent Unit.
I came into the store wanting a pioneer car stereo and that is exactly what I got. This deck truly represents the quality of pioneer. The color of the deck and the back lights match perfectly with my '95 mazda mx-5. This deck is so incredibly powerful it blew out my 2 door speakers and 1 of my speakers in the headrest when I combined the bass boost equalizer setting with the bass+6 feature. I wasn't surprised because they were 14 year old speakers that didn't sound like they had very much life left in them. The deck says its "iPhone compatible" so I decided to plug in my Blackberry storm and it worked perfectly. I was able to control the songs that I have in my Blackberry from the deck itself. It was nice to see the artist, title scrolling through the screen as the song was playing. The slight downside of this deck is the "iPod compatibility". I plugged in my iPod mini and it was not recognized. All in all I love this deck because it gives the user complete control of their speakers. I highly recommend this deck.
