I have a 2014 Impala and the Auto Volume that increase the radio volume as the car speeds up and lowers the volume when it slows down does not work, it is very annoying manually keep turning up the volume and then turning it down when I slow down. I took it to the dealer and they have no answer. The function is on the car and programmed properly, but does not increase or lower the volume. Does anyone have any answers? Thanks
