Can't hear the bluetooth speaker in car
 

So far I love the car everything is ok!!! No problem with radio locking up or not working just having a problem finding the volume control for the speaker when talking on the phone in the car. I can't hear the other person. Been looking for the volume control and I can't find it I have every volume control turn up to 11 and no change does anyone know if there is one and where to can I find it. I also uninstalled the phone and phone book and reinstalled it because when it done at the dealer it was ok. I'm thinking that I may have changed it some how. Thank You Stan
