Im trying to instal my Grom in the cab behind the seat. I want to have the ipod in the arm rest area but is in the trunk now replacing the old changer. Have the Smartenna hooked up and want move my ipod from the trunk. Does anyone have a diagram of how the cable that feeds the changer in the trunk? Want to reroute that cable that feeds the changer back to the cab so that I can use the Grom and Smartenna together. Thanks
