I have same unit and just installed the vga adaptor. i have video through my stereo in app radio but no sound at all. I called pioneer tech support and they have no clue why I have no audio when i connect my iphone 5
I had same issue. i had to send to pioneer and they charged me $230 to reinstall software and perform all the upgrades. I had no other choice because stereo would not come on.
did anyone ever find solution to this topic? I have avic-x940bt as well. I thas the new firmware update and cdiv202navi cord and I have video through app radio but no sound at all. I called pioneer tech and they dont know what it is.
