I removed the head unit and conected up the dension by taking the top pin plug out and using the extension that comes with the dension plugged it back in thus wiring in the link. The radio still works single cd works but how do i change it over to the ipod?? on the head unit it has no option for cd changer does it?? do i need to do something elsse first? Any help would be appreciated thanks mj.
