I bought a f150 it has the iPod cable in the glove box? I didn't buy a iPod yet as I'm not sure which ones will work video/audio wise. So I hooked up my nephews 3rd generation iPod touch and I cannot get the iPod function to work on the d3 it's grey and I can't find anything on how to make it black or un grey to work? I hope this makes sense to people if it does please help? Thank you
