Android auto switch?

@i7even7, your last pic shows already Android running. To unlash the full power you might download some additional programs from playstore (OpenSettings, Nova Launcher, FX file manager to name but a few). To "play" with Android Auto you just have to start it from an alternative launcher two times and you might alter settings etc. Happy experimenting.

Bye for now  Fred

I try over and over I can not go to Android auto, I press 2 times on the Android auto icon

@ap756-fred on your car can you go to Android Auto?

This explanation will be a bit longer, I'll try my very best to address your questions.

AndroidAuto is used as "transport protocol" between CarPC and your head unit. CarPC itself is a substitute for connecting a mobile with limited capabilities to your head unit because AndroidAuto basically limits the type of programs you can use (they have to be certified for car use). CarPC just bypasses these restricions by using a full running Android 9 just needing AndroidAuto as "transport protocol". That results in changing your head unit to an Android unit and you can do anything you can do with a mobile or tablet (which means running any Android program you want, close to no limitation).

Now you understand the different setup programs you'll find by following my recommendations: Settings (the settings provided by CarPC) allows you to alter parameters which developers decided you need to get CarPC connected to your head unit, a hotspot, and so on (pic 5). Unfortunately this doesn't allow to setup all additional hardware you want to use. Therefore you have to use the second Settings menu, which is the Android Settings menu you are familiar with. (pic 4) Here you can add other hardware, developer options etc. To make it complete AndroidAuto (which is used as transport protocol) has its own Setting program. This can't be reached on the head unit, Google has removed these capabilities from AndroidAuto. You can see it only when using an emulator (in my case Vysor) on your PC. Then you might see pic 2. But altering settings within AndroidAuto makes not much sense (only a few protocol related features work) because you are already running a full blown Android on your CarPC.

And now the most important thing on the way to understand CarPCs approach: CarPC is "the man in the middle". Any attempt to see content on your head unit screen has to be rooted through CarPC leaving the car screen as just monitor/input/output. No hardware, no software should be connected direct to the head unit. To name but a few OBD2 dongle has to be connected to CarPC using the Android Settings menu, also any mobile has to be connected to CarPC using Android Settings menu, because CarPC has to process any information/signal before it can send it to the head unit (screen and speakers).

And now the tricky part with the phone: Basically there are two ways to get you "on air", the internal SIM card and your (external) mobile. Which way you want to use depends on your likings. Because using the internal SIM card produces a lot of heat and I'm low on SIM cards I use my mobile as hotspot and phone connection. Best procedure on shorthand: Remove all Bluetooth connections from mobile to head unit - connect your mobile to CarPC using Bluetooth (initiated from mobile using Android Settings) - start and setup mobile hotspot on your mobile - open CarPC Settings and establish connection to your mobile hotspot - test both connections by running Phone and a browser on your CarPC - both will work, done. If you want to use the internal SIM card and don't get it to work by yourself please open a new thread.
