Just bought a Pioneer avic-z130bt with all the bells and whistles from car toys. I would love to stream music from my i-phone 4 with bluetooth. But when I try only the info shows up on the avic screen without any audio. What gives? I thought this would be a no brainer. I do get audio with the cable for the i-phone hooked up, but who wants to open the glove box and hook up to a cable every time? Anyone else have this problem?
