I'm thinking about buying and installing an iCarKit in my car for $150, but I'm not sure if it'll work with the touch. Can anyone verify if it will? I know I can return it if it doesn't work, but I don't want to go through the whole hassle of buying/installing/uninstalling/returning... Thanks.

If that doesn't work, I can always plug it into my factory radio's input aux jack (which is pretty much a headphone jack) but I'd prefer to control my iPod from the radio and my steering wheel and also see what's playing on my radio's display. :D
