Thanks for that info/link.......I'm still leery about doing it though

Is your phone rooted? If not, could you explain how you got to system/usr/keymap/mtk-kpd.kl on the phone please?
edit.....just seen your post in the "root" thread so I'm assuming you've rooted your phone to be able to do that

I'm leery about rooting but would like the ability to map the function button to the camera shutter function......I understand I need root for this.

He's probably talking about opening the app, not activating the shutter within the app.

Try Settings>smart assistant>power save manager          ............and then tick the apps you want to keep running in the background

I think I've fixed this.
I unlocked developer options and ticked "disable absolute volume" for bluetooth.
Now, with all volume turned up to max (car and phone) the volume isn't too bad, still not great but ok.

That's what I'm using as well.

afaik, you need to use a launcher like Nova Launcher since the google search bar is otherwise embedded in the home page. Can't otherwise be moved .

You should raise the conversation volume in your car settings (or by using the car buttons while calling)

Tried that, still not loud enough.

I deleted the device and sync with the speaker again.

That's the first thing I tried. Didn't work.
