mean you not truly follow the guide, or wrong file type.

Need to buy and install Headunit Reloaded on the HU.

HU reloaded - Android Auto server.
Android Auto. Don't need to install should come preinstalled in any new phones.

If older phones, install https://play.google.com/store/apps/details?....gearhead&gl=US
Weird. If your HU is restarting means it's running the commands.
Every time after it restarted, your USB the "b832..." folder gone?
Your ES.apk might have issue? Try a different one.
Can't you just login your already registered Waze from your phone etc?
Anyway Waze do not need to login to use it's functionality.

Hmm.. Not really. I also use the latest ES from APKPure.
Just download again and overwrite, see?

I think the instruction very simple already. Haha.
