Dongle to run Android Auto on Android Headunit (T3 K2001n)

Hey guys!
I brought this China Android Headunit running on T3 K2001n cpu and 2gb of Ram on Android 7.1. The brand is "Roadmark". I tried connecting my oneplus 6T to run Android Auto using USB but everytime it runs the easyconnect mirroring app. So I decided buy the Android Auto dongle (white/black) any feedback on which one to buy? And also is there any possibility to root my system? Please help!

Hi, I suggest to buy the white one as the black ones don't always have android auto only carplay while the white ones have both. I would suggest to go to AliExpress and look for carlinke or carlinkit brand. I have the white one and works perfectly both with AA and Carplay. It's worth to buy as it changes the whole experience of the headunit

Have you tried using Headunit Reloaded? It is an emulator for Android Auto for headunits.
Downloading the Android Auto app on the head unit won't work, as it is just the server (equivalent to the phone) but you need the client (equivalent to a head unit).
You shouldn't need any additional hardware.

Thank you for the reply. Yes, I have the full version of the Android Reloaded redeveloped by Emil, I ran Android Auto in developer mode according to the instructions given, the USB direct mode doesn't work at all only the WiFi direct works but again it's very laggy and choppy the audio breaks so much. So that's why end up buying the Carlinkit for $30.

If you download headunit reloaded from play store after you have bought it and install it and then you download the XDA labs app from forum.xda and then you go to and look for headunit reloaded then there will be a betab available. Download the beta and the WiFi connection with headunit reloaded will work pretty good. Only downside if you are using Spotify when changing track from your steering wheel it will always skip a track and go always to the second one. But only with Spotify

Connect tablet to Android Auto Head Unit

Hi, I have Head Unit that supports Android Auto and Apple CarPlay. So basically I just want to connect my Android powered tablet to it. So I installed Android Auto apk to tablet and it works just fine. However once I connect tablet to head unit nothing happens. Android Auto isn’t starting.
Any suggestions?

There are a few discussions of this:

Android auto and Samsung

hi, my Samsung s20 ultra was working until a few days ago but through mirror link, im trying to connect through android auto but I keep getting a message on my car computer screen saying to connect a compatible USB device, I know AA is built into my fone, It mostly for navigation I need it thanks

Your car needs to be able to handle Android Auto. You say you used Mirrorlink. This is a different system. Check if your car is compatible with Android Auto. My guess is, it is not.

Any way to get android auto as a host on a tablet?

I have an android auto capable vehicle. I also have a tablet that I use for offroading. the tablet is not compatible with android auto. When plugged in to the car, the tablet recognizes that AA is there, and asks me to update, but the play store tells me it is not compatible. AA is now baked into Android, so the only store app that is available is AA for phone screens, which is now being updated to the new version which is like, AA lite. This is on a rooted Lenovo M10 FHD Plus, so roms are kinda out of the question as theyre not available and I wouldnt know where to start writing my own; but Magisk is installed along with busybox and xposed framework. Does anyone know how to either trick the tablet into running AA the same way that my phone does (natively, included in android) or have a solution for this?

Have your tried to use titanium backup (or some other apk extractor) to copy the AA apk from your phone to the tablet and see if it runs?

Not possible, I have no plans to root my phone. I sideloaded the apk though, and it does work as intended as "android auto for phone screens" what I'm trying to do is get it fully integrated as if it were a phone. My s21 ultra for example, doesn't even have an icon for android auto it's installed as a service (afaik) and is only found in my system settings.

What other differences are there between how the tablet runs AA and how it runs on your phone (besides that the tablet has an icon for AA)?

Im trying to make it so that the tablet, hooks up to the car and runs android auto on the cars screen. I don't think AA for phone screens supports host, though I could be wrong?

What do you mean by "host"?
If you can get the AA APK running on the tablet then it should work as expected (show on the car's screen).
So, what exactly is not happening?

Yeah, I didn't realize it would work that way. I ended up taking the harder route, rooted the tablet and installed a gsi rom. Works beautifully now.

Even with APK AA doesn't work in vehicle the same way it does with a phone. I made sure APK is the same version as car. No matter what I try, android auto will load on tablet but the vehicle will not recognize it and launch it on car screen. There must be a way to do this with a rooted tablet and AA APK. Anyone tinkered with this? I have a 2021 f-150 which even supports wireless AA from my phone.
@evilsway were you able to get this to work?

I guess Android Auto requires a device which is capable to make phone calls...

installing android auto on an lte tablet.

Found a lot of info on this for rooted devices. but not to much for non rooted devices
i want to install AA on a LTE tablet that will stay in my car. the tablet will run other car related apps.
but im tired of having my phone tied up playing music draining my battery. specially on long trip.
also i cant record videos or talk on the phone and still have music lol i know things i shouldnt be doing anyway..
is there anyway to make it work. i tried to sideload it. but got an error 22 that android auto needed to be installed on my os.
any help would be appreciated

maybe try AA emulator on this tablet?

Android Auto app is not targeted to tablets, only phones. And since Android 10, Android Auto is a system app, not a user app. So, if your current Android version is 10 or higher and you sideloaded the Android Auto apk, it will not work. To make it work you'll need to root the tablet and install Android Auto as a system app.
[GSI] Fix 'Communication error 22' on Android Auto
If you've installed a custom ROM that doesn't come with Android Auto pre-installed, you'll get the following error when connecting your phone to your car (the Android Auto app opens correctly, the error is only shown when you connect to the car)...

The easiest alternative is to use your tablet as an Android Auto receiver using Hedunit Reloaded Emulator. It's available on the Play Store and is very cheap. It has even a free trial app with a 5 minute limit if you want to test it.
When installed, this apps acts as an Android Auto receiver. This way if you connect your phone to your tablet using an OTG cable (or a USB-C to USB-C cable if both devices have this port) your phone will detect the tablet as an Android Auto compatible headunit and show stuff on it.
You can use this app in Android headunits if they don't have Android auto compatibility, as long as they support USB OTG mode.
