I have searched and searched but have not found a clear answer to my question. I would like a device that connects to the back of the nav unit, tricking it into thinking a CD changer is installed, and serves as a direct-in to the unit. Not interested in integration (I don't like the 99 song playlist thing with the popular integration unit) and don't mind controlling the tracks from my iPod itself. I would, however, like for it to charge. Could someone please direct me? Thanks!
