You can start with this:
1. Reinstall Android Auto
2. Reset the car multimedia and pair again.

In my Suzuki Vitara Hybrid, it works wireless or connected to USB cable.
I did it with no result. In my Megane 4 only wired connection is available. USB cable is ok. Even tried in other car, no success as well. Don't know what happend.

It is possible that your GMS fix to not be fixed in this way. Yo have no visual errors but some apps will not run. Can you open AA on the phone with no errors? What firmware do you have on the phone?

Ok, I missunderstood you before. Any idea how to solve it?
Car is OK.
Cable is OK.
Try to copy a file between phone and the computer with that cable that you use in the car. If you can copy a file, will be the GMS fault.
I can tell you what I have on my phone:
Android Auto= 7.3.120243 (beta)
Google Play Services= 21.24.56 (040408)
Google Play Store=28.9.12-21
Google Services Framework= Ilham version.
EMUi=10.1.0.121

MicroG GmsCore v0.2.23.214816 has been released on 2022-01-25.

This is a MAJOR release with significantly improved features and a number of important bug fixes, including specific fixes for Android 12. Also, it brings back the ability to pass Safetynet under the same conditions that would allow this with Gapps instead. Changelog / Release Notes: Exposure Notifications: Add support for validating signatures on key files (only for DE and CH for now). Thanks @cgrigis Add support for more detailed API and use Advertisement version 1.1. Thanks @Elsensee Improve permission checks, especially for Android 12. Thanks @bubu, @fynngodau Cloud Messaging: Improve reconnecting logic. Thanks @grote SafetyNet / DroidGuard: Implement DroidGuard without additional helper. Allow using external DroidGuard via network Easy check for SafetyNet functionality in settings Device profiles: Allow to spoof device identity Import device details from profile file Location: Update UnifiedNlp to v2.0-alpha7 Improved reliability of service Improvements and bug fixes (as always) New features SafetyNet / DroidGuard The updated SafetyNet implementation runs proprietary DroidGuard code privileged in the com.google.android.gms package name. This is required on at least some devices to pass SafetyNet. However this features is disabled by default. If you don't want to run proprietary code by Google on your device do not enabled SafetyNet. As of now, microG SafetyNet implementation, once enabled, should work on all devices and ROMs that would pass SafetyNet attestation with original Google Play Services. This means that ROMs that are rooted (= come with a su binary that allow privilege escalation), with unlocked bootloader, or for some other reason do not pass the CTS or trigger the SafetyNet system will fail SafetyNet attestation. Hiding or spoofing such details from DroidGuard/SafetyNet is out of scope for this project, but techniques to allow passing SafetyNet on custom ROMs should equally work with microG.

Device profiles This features is mostly useful for Huawei devices or other devices that are banned from accessing Google services. Choosing a profile of a non-banned device should allow using the device with Google services. For now, two device profiles are included with microG (Nexus 5X with Android 8.1.0 and Moto G with LineageOS 14.1). If you are a developer, you can easily create a device profiles based on data gathered from a device. See this file for a sample device profile. Once created, you can import device profiles in microG settings (under "Device registration") to test the profile. If you are a custom ROM developer, you can add a custom device profile for your ROM by placing an appropriate device profile in /system/etc/microg_device_profile.xml. This can be useful to spoof the details of the original vendor ROM.

========== END RELEASE NOTES ==========
Closed repository issues likely fixed with this release: #1567, #1606, #1644, and others. Downloads are available via F-Droid microG repo and Github. Native F-Droid packages will arrive a bit later. 3rd-party installer bundles will be updated as per each developer's workflow. (MinMicroG has released a new STABLE build based on this microG version. See the announcement for it here: https://t.me/microG/54913 Github release page for this update: https://github.com/microg/GmsCore/releases/tag/v0.2.23.214816 Here's our summary of the previous update released on 2021-08-23: https://t.me/microG/39598

    @Eini666 and @badmania98 you glorious bastards.
    EMUI downgraded to 10.1.0.121

    About to install Googlifier.

    As usual, you guys find yourselves in Prague beers on me <3
    All thanks should go to to @badmania98 I only had to downgrade and install GMS 3 days ago, so I just read the entire guide and I still remember what and how.

    Hello everybody!
    I'm here to thank @badmania98 for helping with installing notifications for GMS services for a Huawei P40 pro.
    I downgraded from EMUI 12 following the steps described on this thred. I also had a weird problem (maybe others had it) - downgrade to EMUI 10 via OTG connection from a 64gb Kingston stick didn't work - the stick was formatted correctly. It was solved by using another older 8gb stick.
    After installing the GMS services, I contacted @badmania98 who was willing to help me the same evening - the process took an hour or so, during which time thousands of steps were taken - I consider the price for the service more than fair.
    Very good communication and the best result!

    Hello there,

    I am having a bit of an issue here, maybe you can help me out.
    I had EMUI 12 - Huawei P40 Pro (factory reset) and I downloaded latest official HiSuite to downgrade to EMUI 11.

    So my info was:
    Build version: 11.0.0.249
    Model: ELS-N29
    Region: C185
    R number: R4

    Edit 1.0:
    Followed your instructions and I downloaded a DLOAD file provided by you for version 11.0.0.230 (used your C432 instead of C185) (C432E3R6P4) and now my phone info reads:

    Build: 11.0.0.230 (C185E6R4P4). There was no change in region it seems?

    THE (UPDATED) ISSUE
    I am unable to use HiSuite or OTG method for whatever reason to downgrade to EMUI 10 to install Googlifier.

    A) I tried using HiSuite Proxy for ELS-N29 C184 (R4) to roll-back to 10.1.0.114 and 10.1.0.131 both. But soon as the files are 100% downloaded I get error "Failed to update"

    B) I downloaded DLOAD for 10.1.0.131 (from your old post) --> Elsa-N29D 10.1.0.131(C185E9R4P1). But when I try to install from recovery mode I am getting: "Software install failed: incompatibility with current version)

    Please tell me what am i doing wrong here, I spent all day reading and re-reading your instructions not to be lazy but i'm hitting a wall for whatever reason....
    Which hisuite version are you using to downgrade ? Latest version V11.0.0.610 you need only do downgrade from emui 12 to latest version od emui 11 and to have latest version hisuite app on the phone.
    After that you need to uninstall hisuite from computer and install 10.1.0.550_OVE-BUN but only on computer with no upgrades of firmware in phone and computer.
    Hisuite Proxy and Hisuite 10.1.0.550 will give you possibility to downgrade from 11.0.0.230 to 11.0.0.121

    With husuit proxy but could not find firmware below 154
    That is because you used v2 on firmwares page. You have to use without v2 on the address link

    This is good for you: here.

    6. The transfer files between Computer and phone is available on the downgraded firmware (10.1.x.x) when you use a certain USB-c to USB-c cable. In this case a UGREEN, US355, USB-C To USB-C, 3.1, Gen.2, PD, 5A, 100W, 4K, 10 Gbps cable has been used. In the same time, using the original USB cable or other ordinary USB-c to USB-C cable have not activated the file transfer.
    Harmony TP cable works also, in case your computer/laptop doesn't have USB-C port. You can build/make one (search the procedure on YouTube).

    Hello everyone,

    I want to share my experience here.

    I posted earlier a problem on xda "Can't downgrade P40 Pro ELS-N29 C432 from 11.0.0.260 to 10.1.0.131"

    I tired many solution for several days and nothing worked!
    Then I contacted badmania98 and he gave me the right and only solution to downgrade my P40 Pro from 11.0.0.260 to EMUI 10.
    He provided me with the corresponding links and gave me a step by step procedure, shown in pictures that are highlighted by numbers..
    " 1. Press this 2. insert that 3. etc... " and then he doubled check my work before I proceeded in Hisuite Proxy to make sure that the filled info about base, Cust, Preload and the software are 100% accurate.
    I was able to downgrade my P40 Pro to EMUI 10 😁

    Now here's the best part: He gave a private service and installed GSM on my phone using TeamViewer. He used his own files to install GSM on my phone... This service allowed me to have Google Push notifications working on my phone without disabling the Google Play Store 😁
    Google service is working, maps, push notifications, everything related to Google is working now as if this phone originally had Google Pre-Installed in it 😁

    It was a great service!

    Thank you so much
