I too have been suffering with this in my 2007 (New Style) GMC, and I-phone 5. it worked very well when I got this phone, along with the Droid incredible before it. I believe the i-phone 5 was an early version of IOS-6. during that time after one of the i-phone software updates this started to happen. (still IOS-6). I worked with it back and forth trying to reslove the issue but everytime I believed I solved the issue it would come back. I finally updated the phone to IOS-7 and no change. I am going to pull the unit from the vehical and update the firmware, but I am not confident from reading these posts that this will work either.
I am chiming in to see if the phone software version change may point Mr.Costar in the right direction. This is really not functional right now and I have been struggling with it for roughly 9 months. I need to pull the unit to hook up the aux audio plug anyway but it would be nice to find a solution for the phone. I have a really neat device that fits a need and I am using the phones speaker phone function instead of my nice hands free unit.
