Summary: I've had this stereo for over 1.5 years as soon as I got my current car one of the first things I did was get this stereo. I wanted one with bluetooth so that I can talk hands free while driving and it works good. I really like all the features of this stereo and I love all the different colors. It looks really nice and works very well. Also it's very simple to pair and connect my smartphone to the stereo which I love.
Summary: Bought this for my son as a gift. Easy to use controls, easy install plenty of power. Its wired to the an amp and sub, but directly feeds the 6.5's in the doors and the 6x9 in the trunk and took about two weeks to blow the stock units. Can customize the color and the screen. It made a teenager happy, that works for me.
Summary: As Electronics continue to take a life of their own the need to find a device that dosen't "argue" is a must. This Pioneer 6400BT works great with my Zune or an Apple. Sound quality is very crisp and highlighted. I ran a single 12" sub with it. The color options are neat and the sound options are easy to use. The interface is easy to navigate and dosen't become a frustrating game like other decks of lower quality.
Summary: I bought it in used/like new condition. I must say i love it. I just turn on my car and it auto-connects to my android phone and start playing songs, i can dial and receive calls in my car without taking out the phone from my pocket, very very useful.
