Personally, I find it rather appalling that Alpine produces a line of "made for iPod" head units and then requires you to purchase a separate and rather expensive cable to actually use the features of those head units.However, that's the way it is, and this cable works as described. I see that there is a newer version which allows for control and charging of the iPhones. Oddly, my older cable (which definitely does not have a converter on it) actually allows me to access my iPhone 3G music in the exact same fashion as on my iPod Nano (gen 2), as used with my Alpine IDA-X200 head unit. I haven't checked to see if it actually charges the phone, but it would seem to be the case that it does not, unless my cable is a magic exception (unlikely...)Anyways, it's a cable, it works, and you should probably just buy the newer version.
