The AA must be the last

Reinstall last GPS

Go to be sure that system recognises it as last version (list of app and Titanium too)

Switch OFF WiFi and Data

Using Titanium uninstall GPS

Reboot

Let verify that the system recognises as absent GPS (you must receive back a lot of error messages)

Install GPS 12.6.88

Reboot

Using Titanium Backup Pro preserve GPS from update

Reboot

Switch ON WiFi and Data

Ok, I just did it like you say and this happens....

Everything was fine until install GPS 12.6.88, after the install the errors still appears (Google play services won't run unless you update) then I reebot the device... Open Titanum and uncheck the updates and the errors still appears and I reeboot... When I turn on the devices the notification that I have to update GPS still appears and also appears errors like 'com.gapp.xxxxxx stop working....' Turn on WIfi I tried to Open Play Store but nothing...

What happen?

And now... I tried to install GPS lates version and I can't... The error messages still appears... Tried with APK mirror and nothing... Seems like GPS is broken and I don't know how to fix it...

I have to do a clean install / flash rom because GPS was broke... I root my device and did all the steps you say and it's the same. It's not a conflict with google acoount because a my first attempt mi google account was "enable" and the second attempt was without any google account on the device... I don't know if is a problem with Titatinum or what...

Tried following a number of different ways but cannot get AAmirror to appear on my head unit...my head unit for ford transit just says 'back to Sync' and no SU permissions appear on my OnePlus 5T handset like it should...any advice or support welcome...I've tried downgrading GPS but nothing would work including AA as it said GPS needed updating to work....
[Android Auto General] slashersnakepit:
Let me explain you step by step what I did to make it work.

First of all remove all the apps related to Android auto, the idea is to have a clean installation.

If you already have latest version of Android auto don't uninstall it.

Now, you need to downgrade google play services not any similar, I mean it should have the same name because you may have any other similar.

To downgrade you have to disable google protect in settings - device administrators and any other new apps listed there related to google because it may use GPS and can make a mess on your phone.

After doing that, go to settings and then apps and look for google play services, open it and tap on uninstall updates. Once done just verify that this old version is minor to 12.6.85 , I'm assuming that you already downloaded a working version of GPS 12.6.85 from apk mirror according to your phone dpi and processor architecture, install this old version.

Be aware that google play services will be sending messages saying that you need to upgrade it, just ignore them but also it will try to update it by itself without any consent or advise so you should try to block it using titanium backup pro , there in the main menu look for market auto updates section and once inside search for google play services and uncheck it and save the change with the top sign.

Then just install carstream, aa mirror and aaunlock and then follow the steps they said before with both apps but remember you should have root on your phone and Grant root access to them once connected to the car otherwise it might not work

Can anyone recommend a good cheap older phone that's easily rootable that works with this? Figure I'll get one to leave in the car and use wifi and my phones hotspot. I was thinking about a rpi3 but then I would have to get a gps module also.
[Android Auto General] 2coolium:
As of a few days ago, android auto keeps updating itself and once updated says GPS must be updated . I've had this working for a while so I'm kind of stuck. I've tried blocking it with everything but a wall, will try that next. GPS is 12.6.85 and blocked with titanium.

Thanks for any help

Because carstream has support for non-touchscreens and it's working flawlessly apart from the unlock issues.

No, you have to install through an apk. Also, you need root.

It is important to have relevant version of AA and GPS ??
[Android Auto General] fadinizjr:
You're welcome.

That's it you just need to reboot (and redo this if AA mirror disappears from your android Auto Head Unit)

I don't use any specific AA or GPS. I think you can have the newest ones and it will still work.

It should work.

Did you select the last icon on the android auto interface. AA Mirror should be there.

When you were prompted to reboot, do you granted root permissions to AA Mirror and AA Unlock?

Also, on the first time you run it AA Mirror should ask for more root permissions and screen overlay.

I have cleaned cache and data of unlock.apk, repeated the unlock procedure and now I was prompted to reboot

Oh, now I understand your question.

Ok... the first time you open the app it should ask for some permissions including screen overlay or something like that. That is the functionality that enables the touch screen also change system settings permission or something like that.

Dear friends,

I spent a lot of time fighting with carstream to be possiblem to use it in car system (in Android Auto).

I made hundreds tests with many versions of Google Play Services (BTW: please use GMS not GPS as a shortcut to find this system app because the name is GMS) and different versions of Android Auto app.

And after hundreds tries.... ta-dam! - found a solution. In my case it works with this combination of versions:

Carstream 2.0.0 (patched with Windows AA patcher: https://xdaforums.com/android-auto/android-auto-general/app-simple-utility-to-patch-install-t3758294)

Android Auto 3.4.582534 (downloaded from APK mirror)

Google Play Services 14.5.75 (ver. 12.6.85 downloaded from APK mirror and updated automatically to newest version)

(this is working on my Galaxy Note 9 with Android 8.1)

Please note that I have newest version of Google Play Service and despite this it works!

So I don;t need and firewalls and TB settings to stop GMS updated (it coudn't be stopped even with Tiatanum Backup autoupdate switched off). But the trick is that all settings I've done - according to the instruction in theas thread - using downgraded GMS to ver. 12.6.85 (before it was auto updated to ver. 14.5.75). All settings (permissions for AA etc.) I've made with AA in developer mode and switched on server option in AA.

After this Carstream appear in car system only in audio options (to play music not video). Then after GMS updated to the newest version I switched off server option in AA and in the next step I made Carstream unlock (root) option again and reboot the phone. Then finally in the car system Carstream appeared on tha app lists (not only in audio options) and - tadam! - works.

Hope it can help for other people. Generally: do as many test as possible with different combinations of app versions and settings and you will find the solution :)

is carstream working for anyone? Getting error 8!
[Android Auto General] zencooler:
No prob. The steps I've done to get Carstream working with newest Google Play Services (no need to block autoupdate in any way):

01. Download Carstream 2.0.0 and patch it with Windows AA Patcher: https://xdaforums.com/android-auto/android-auto-general/app-simple-utility-to-patch-install-t3758294 (it will patch and install Carstream on the phone)

02. Download and install Android Auto ver. 3.4.582534 from APK mirror website (if you have newer version just uninstall it before installing ver. 3.4.582534)

03. Download Google Play Services (appropriate for your phone) ver. 12.6.85

04. Remove (uninstall) current version of Google Play Services - I did it using Titanum Backup with wiping application data and cache (uninstallation may stop during the process but it works and when it's done plenty messages are displayed on the phone about lack of Google Play Services and so on)

05. Restart the phone

06. Install Google Play Services ver. 12.6.85 using downloaded APK file and now hurry up to do next steps before Google Play Services will autoupdate (if you are afraid you can switch off data transmission and wi-fi connection for that time)

07. Start Android Auto on the phone (without USB connection to car system)

08. Click on the menu on the top left (three bars) and click "Information" (or "About" if your language version is different)

09. If developer mode is not enabled, click on the bar "About Android Auto" 10 times

10. Click on the three dot menu (on the top right)

11. Click on "Developer settings"

12. Click on Application Mode and change the option to "Developer" then go to the bottom of the developers settings and check "Unknown Sources" (this option must be checked).

13. Click back then go to the three dot menu and click "Start head unit server"

14. Connect the phone to car system via USB and accept any permissions it may ask you for

15. Check if the Carstream appear in the audio players menu (headphone icon) in your Android Auto car system

16. Disconnect the phone, start Android Auto again on the phone and go to the "Information" and click on three dot menu then click "Stop on the head unit server"

17. Let the Google Play Services to autoupdate now (of you have data transmission and wi-fi off just switch on them and wait until notification about updating Google Play Services appear)

18. When the Google Play Services is updated (current ver. is 14.5.75) start Carstream on the phone and go to the three dot menu then click on "Unlock[Root]" and grant Root access when prompted

19. Reboot the phone

20. Connect the phone to the car system and... voila! The Carstream appear in the application menu on your Android Auto car system (last icon on the bottom right corner). You have also "All application" menu here as you have still developer mode switched in developer settings in Android Auto (according to the point 12 above)

Hope this helps. Regards!

This only partially worked for me. Does NOT work in my vehicle.

When connected to head-unit-server on my PC:

Clicking on the lower right hand corner speedometer displays carstream and it plays videos properly.

When connected to Android Auto in my vehicle:

Clicking on the lower right hand corner speedometer only displays 'Return to Kenwood home' and 'All Android apps' the latter of which does not show carstream. Furthermore, I can select carstream from the media apps list in Android Auto on the screen, however, it will not show video regardless of attempting to click 'play' on the car screen or on the phone.

Any ideas? Did I miss something? Is this method broken due to updated FW/Android Auto/etc?

Vehicle head unit - Kenwood DDX9705S (running firmware from 05/28/2018 before this article was posted / version S_V1_2_0009_1900 .zip)

I got the idea to use CarStream instead of AA Mirror to have my phone screen closed and watch what I want, but with that codec problem, it won't be "what I want" but what I can watch through it.
