hey guys
i know this topic has been beaten to heck, but trust me when i say that i've spent over an hour on google and on this forums reading up on the problem but all the solutions haven't fixed mine..
I just installed my AVIC F700BT today and like so many people here, I plugged my iphone 3GS into the adapter (genuine Pioneer one), connected the USB, connected the RCAs. the unit recognized the iphone but the cursed problem arose...NO SOUND. i checked and rechecked the AV settings and ensured AV1 was set on "ipod", i even tried different combinations of "AV1: iPod, AV2: video", etc etc
