so i finally got my Iphone 3gs connected to the D3 but when a call comes in they can hear me but i have no sound over truck speakers what so ever. also i have no sound when i stream audio from the unit aswell. is there a setting i am unaware of? any input would help. thanks, william

yes, select pioneer bt on your iphone and make sure your bt is on in settings on the iphone.

make sure you hit the play button on the d3 screen
