I know people think this concept is crazy, but i am trying to confirm if a car head unit is compatible with audio streaming VIA built-in Bluetooth. I use my ipad in our mini-van during long road trips so the kids can watch movies on it. I use a FM modulator currently; it sucks. Has anyone had any susses streaming audio through a Dual brand head unit? I am looking at either the Dual XHD7714 or the Dual XDMA6415. Any input would be appreciated. Thanks!
