Hey guys so i got my Bespoke system finally installed on my car(since when i picked up my car 3 weeks ago and they had not installed it on there), i have liked it so far. it looks good in the car, bluetooth is awesome, i love the pandora capability. BUT when i try to hook up my iphone with a regular apple cable into the connector by the shift knob and open the bespoke app, then click on bespoke on the headunit it dosent do anything it just sits there. so i did some research and i guess there is a cable that i am missing. its a usb/aux to the iPhone. Is this cable supposed to come with the car, or am i supposed to go buy it, or am i just doing something wrong?
