Right. I lose the trip data screen which always comes on when I start the car because its the only place I can see the miles driven on the current trip. The dash screen, which I rely on for miles/kwh and miles remaining doesn't show trip miles, although you would think it would
I have found that if I turn the volume way down, it doesn't retains that setting the next time I start the car while still showing the trip screen but instead plays at a low volume, so every time I start the car I have to turn the volume down. It's just that it's a little unsettling having the radio lurking in the background when I don't want it at all, as I rarely listen to the radio. There should be an on off click where you dial the volume to turn it off

My guess is that this is an inherent problem with modern software-controlled radios and steering wheel controls.
The rotary control that appears to control volume is not like the old variable resistor volume controls on transistor radios. It's just a rotary dial with a counter on the back of it. By moving the on/off switch to a push button in line with the axis of the knob, there's no min or max in the control now, just plus and minus from where it is when you start rotating. That way the plus and minus buttons (and mute) on the steering wheel can adjust the volume without messing up the relative position of the dial control. Does anyone remember the home amps that had a motorized volume control that could be adjusted from the remote? I assume they were still variable resistors (but it may have been just for show).
By having an infinitely rotating dial and software interpretation of what that means for volume, any part of the system can have its own default volume, like turn by turn instructions etc. Manufacturers of these all in one systems see that as a benefit which outweighs the edge case of the system being on but making no sound.
