I've just got myself a new alpine head unit with iPod cable, that works with iphone for its music, but was looking for a dock i can fit that has a pass through ipod dock connector on it. I could just get another iPhone dock or universal dock cheap on ebay, but they're a tad expensive for what they are. Anyone know of any good products? I dont need any addition feautres like FM or audio through, just simply a dock connector pass through. the stereo does all the charging and music etc.
