gotta go with auxiliary audio cable input and/or DICE/Intravee IPOD adapter... The Aux audio input gives you 1/4" input upfront for ipod/smart phone/dvd audio, etc. Cost = $40. The adapters give you integrated control of ipod from nav screen/steering wheel inputs, etc... Cost= $300.. I've also added backup camera and TV Tuner but that's getting carried away now
