nice product, two concerns, 1:How does it get rid of the noise and distortion added by the oem's built in amp out of the high level inputs? and 2: I hate oem looking decks and such, just very boring looking at the same thing all the time, plus very few have the features that I want, for example, they may have mp3 but lack wma etc.. however, that being said it is a definite step in the right direction as far as keeping up with the auto makers and their obvious hatred for aftermarket.
