I can't seem to get an answer anywhere so I'll try here as a last resort. I've got an 05 GT w/shaker 500 radio. The quest is what is the AUX button for? I can't find any input jacks for it, and the owners manual don't tell me squat! I'm feeling quite stupid right bout now. ANY help would be appreciated. Ford just tells you it is for an AUX INPUT. OK........ like what? IPOD? SIRRIUS? XM? and if so where do you tie in, or plug in? Nothing in glove box, or console. Thanx guys.
