Summary: I have always loved Clarion products, ever since my first head unit back in high school, whenever I buy a new radio it is always a Clarion. Install in very easy, especially in older vehicles with less complicated wiring. Connects great to my iPhone to both play music and charge my phone. I wouldn't trade this stereo for anything else, I love it so much I even bought one for my girlfriends truck last Christmas.
Summary: The sound on this unit is excellent with the right speakers, it does sound a bit bright if you use speakers that are already on the bright side. USB works great and mp3's sounds good with the bit rate of 128 or higher. The custom eq adjustment of bass mid and treb could be a little more user friendly but For the price you can't go wrong.
