AUX volume not moving up
I’ve got the base audio system, and an upgraded carplay head unit. the head unit plugs into the aux port but when I select the aux, the volume is at the bottom, and i can’t move it up. i’ve tried making sure the aux cord is plugged all the way in on the head unit and glove box side. i’ve got a fm transmitter in right now and it sounds terrible lol. any thoughts?
