I have a 2016 GLE 350. The radio used to come on when I started the engine, but has stopped doing that. The backup camera comes on and turns off as it should, but I have to manually turn on the radio. If I leave it on when I stop the engine, I still have to turn it on when I restart the engine. I don't find an option for radio auto-on. Do I need to reset something?
