Just installed the d3 in an 06 mustang. Had the shaker 500 taken out. Everything works fine, except when i plug in my video ipod, music only comes out the right speakers. Is it the plug? It can't be the speakers, they work for radio/gps/cd/dvd. Do i have to fix some settings on the ipod? I dunno, thought posting might help.

Try resetting the ipod to factory settings and making sure both ends of the cable are connected snugly.
