Phone volume issues
 

When using cell phone in/through car, when car is asking/speaking to me like say command, volume is loud and when I say call then say name it repeats what name or command I programed back to me in a very very low volume. When I'm speaking/listening on phone once connectedvolume is good. all sounds/volume ONLY comes through passenger side door 2007 maxima sl. In my wifes 2010 maxima sl all sound/volume using phone is perfect and comes through front speakers. My question is why volume (my programmed commands) is so low and why sound only comes out passenger door ??
