Hello all. I just did my first self install of a Pioneer AVH-P8400BH into a 2007 Dodge Ram 1500 Megacab with with Infinity sound system and factory Nav unit. I've got everything to work as it should, but for the life of me I cannot get the phone call audio to play on my speakers. I have an iPhone 3GS and I can get the Bluetooth to link no problem. The Bluetooth Audio plays just fine. I've had some people test call me, and the call is received through the system and the people who call say they can hear me just fine. I just can't hear them. Only time I heard anything at all was when I turned up the head unit and iPhone volume all the way, and I could very faintly hear a staticy sound (like a buzzing). I've tried to re-sync and unplug the iPod cable. Also, I turned off the Bluetooth Audio function on the unit. Maybe I need to follow a different order of setting up. The only wire I see anywhere that is not connected is the blue one for a power antenna, which I do not have. Seems strange that I can hear Bluetooth Audio just fine, and all 7 spearkers sound great with every other source. Just can't hear phone calls in my vehicle. Any ideas? Thanks in advance!
