Hi. Just bought a 2018 Trax Premier. My question is, “Why does the radio come on every time I start the car?” I have told to turn the radio before I shut the car off, (duh?) it is off but always starts with the car. Have been able to silence it at ignition but the radio still comes on. I don’t understand the engineering for this but would like to turn the radio on when I want it not when the car starts. Thank you for any help.
