I can play music with no problem and the phone pairs without any issues. The play button, stop, and pause work but when it comes to changing song the forward and back buttons don’t work. I have to change the song though the iPhone, I can’t change it thought my AVIC-D3 head unit. Does anyone know how to fix this?

When I first paired the iPhone think it worked initially but hasn’t work since that first time.

This doesn't work for me either, but I haven't really looked into it too much. I wish there was a fix, b/c unlocking the phone and pressing next track is a PITA while driving.
