I am having problems with audio from my iPhone. I installed my x930bt today, with the iu51v cable. All connections are good. I get sound only from the front left speaker with the iPhone. It does not matter whether I use Pandora, Aha, or my music saved to my phone. Sirius and FM works just fine on all speakers. My iPhone works fine with my headphones. Any ideas? Thanks.

Well, after screwing around with it some more it looks like its where the 51 cable connects to the pioneer input cable. If I pull the plugs apart just a notch, it starts to play out of all speakers.

So im haveing the same problem. When you say 51 cable, do you mean the cable that goes from your iphone to the Pioneer USB/Mini Sterio jack?

I have the exact same issue, so what your saying is too just play around with the cables ?
