My Sony works fine , and without any super visual eye candy to drag the price up . I also get high and low pass filters , 7 band eq , front and rear rca's , subwoofer rca's , mp3 playback , and a remote . Works for me .
Works great if I keep it clean , AZ is dusty , and the dash gets it the most , Needs cleaned only if I go on several trips out in a month .
Now my Sony changer I had before never missed a beat , and I never put a cleaning disc anywhere near it .
They have one out this year with a one gig mp3 player faceplate you can load up in the house via usb .
