Okay, so I spoke to the rep. at Pioneer who recommended I try out a different iPod / iPhone with the unit just to see if it was the unit or the iPod software. So, I borrowed my wife's iPhone, plugged it in, the unit cataloged all the songs from her iPhone, and the voice commands were recognized! So, I thought maybe if I connected my own iPhone it would work since the VR catalog got "reset" in a way. Sure enough it worked!! So, I suppose the iPod app was in a bad state or something. Who knows! All I know, is I'm glad I can finally control my songs and calls with voice commands once again.
