Well the knockoffs work fine for me in my Escalade as long as I dont use my iPhone to playback video, as I mentioned earlier the iphone requires the "chipped" cables, which are the $50 cable from Apple. If you use an iPod (which I also got) it works just fine for both audio and video in my Escalade, clean sounding and works fine.
But thanks for the feedback, I will probably just buy the apple one since its the same price as the pioneer since I do want to use my iphone with this deck.
