I have a 2012 sienna LE and a samsung galaxy phone hooked up through the bluetooth feature. When I make calls the volume is SO loud I can't stand to use the feature. I've tried turing my phone's volume down and the stereo volume down and nothing is working. Guy at the dealership said while I was in a call to try turning the volume button up and then down several times because sometimes the bluetooth volume gets "stuck" and that should fix it. Well it hasn't after multiple tries. Any other suggestions?
