i've tried to mess with the EQ numerous times custom and preset and still sounds like garbage. I've even thought about buying the mic to try to fix it. Could it be the iphone cable to the headunit? Its a pioneer cable.

Everytime I connect my iphone 4s to my 930bt via the iphone/ipod cable to play pandora, the audio seems off. The music (guitar, bass, drums) is at a very high level, and the vocals are very muted. You can barely hear the lyrics from the vocals?? It cant be my phone, because it does it with every iphone. I recently did the firmware upgrade hoping that would fix it, but no such luck. Any suggestions or has anyone had this issue? thanks!
