I am now using a FM Transmitter (Monstor iPlay) which is good but I am looking for the best quality. My headunit I have in my truck now is a Pioneer DEH-P5900IB and is iPod ready and has a AUX input. I am thinking about go to my local Bestbuy or Circuit City and buying this. It is the "Pioneer iPod Direct Cable (CDI200)" I am wondering before I spend this money, do you think that this will work? I mean, the iPhone basically works with FM Transmitters and iPod docks that I've tried in the stores and iHome and everything. What do you guys think? If I can do this, This will be so sweet and the quality will be full. Please let me know guys!
