Kenwood Excelon  KDC-X689

I've had this unit in my old S-class for almost a year now. AWESOME! The only problem I can think of is sometimes when you turn on the ignition and then go to "start" position, the radio trys to flip the face around to hide it. Once the engine is started (depending on where the face's position is) the face may be in hiding, AND THE STEREO IS STILL ON. Real funny when the music is playing, but the face is hidden. :) If your unit flips the face when you turn on the ignition, just wait until it stops, then start the car. No problem. I bought this unit to run MP3, Sirius (with a SIRKEN unit) and because it was the only unit in the line that still had the MASK flip-face. I'm old-school, my older Excelon was a flip-face too. Great head unit. Tons of features! I love the built-in crossover system and the voice-supported MP3 listing. Super cool! Local shops wanted $500 almost a year ago, got it from OCS for around $260! Now it's even cheaper.

best deck for the money, lots of great featurs, great sound quality,and the revolving face is just cool!

I just bought this unit two weeks ago and let me tell you it sounds great. The many adjustments that you can make on the head unit to make your audio system sound better is unbelievable. I would recommend this head unit to anyone not only for the quality of the stereo, but also the price.
