I dont think its in the settings like the wallpaper.
There is an icon for that called boot image or something like that. If you have Nova installed you go to all apps and its there.

I think what it is with hotspot on iphone is that after a period of time hotspot turns off if nothing is connected to it. All I have to do is open hotspot settings window on my iphone and Head unit reconnects to it.

Can you also check if Waze lets you change it's sound settings. Its the speaker icon on the bottom right which has 3 options.
It never works on mine.
I got the mirroring to work with an Iphone using Phone link native app.
Just update the app. Didn't have to do anything on the phone. It connects to the unit wirelessly
