Any idea on why wired Auto works, but not Wireless?

We've been looking for a new car recently and found out that wireless android auto connectivity is not a given thing in any car make or model or variant. Some models may offer it, for others it's available at a premium and others are limited to wired connection.

So, first make sure if your car (make, model, variant, build) actually supports wireless android auto connections.
Check with your Renault dealer.

My car allows for Bluetooth pairing with my phone, through another way in the same multimedia system (ie separate from Android Auto).

I have no idea on how to make Android Auto to work over a Bluetooth link, nor on how to debug what is wrong/missing.

[EDIT]
I just found a FAQ on my car's manufacturer website providing the steps to pair the multimedia system with Android Auto wirelessly, the exact steps I couldn't make work in my car.
To be precise, that special "wireless" button on the wheel exists on my car, but pressing it at the right time doesn't yield anything.

TL; DR: Everything weights in the way of my car supporting wireless Android Auto, nothing weights the other wya, yet it does not work and I do not know how to debug that.
Any steps to follow to achieve that?

    Berbe I have no idea on how to make Android Auto to work over a Bluetooth link, nor on how to debug what is wrong/missing.

    I believe wireless Android Auto requires Wi-Fi (source).

        de0u Wrong belief!
        I would encourage you to read at the source, rather on some random thrid-party websites.

        The official Google documentation on Android Auto explicitely mentions Bluetooth.

        There is even a link to the Android website listing compatible cars, in which my vehicle appears, for the expected manufacturing year range.
        Yet another intel my car does indeed seem to support wireless Android Auto.

        Is there anyone here with knowledge on how to debug non-working wireless Android Auto on Pixel 6a?

            Berbe I don't use Android Auto, so I definitely don't know the answer to your question for sure, but https://grapheneos.org/usage#android-auto says:

            For some cars, baseline permissions for wireless Android Auto are needed even when using wired Android Auto. Therefore, if wired Android Auto is unable to connect to the car with only wired permissions granted, try granting wireless permissions instead.

            If you're using both wired and wireless, do you have both enabled in Settings > Apps > Sandboxed Google Play > Android Auto?

                other8026 I cannot use wireless.
                This messages seems to be intended for people having the wired connection not working. Android Auto works on wired connection for me.

                But yes, I tried activating both options when I tried to make wireless working, to no avail.

                  The official Google documentation on Android Auto explicitely mentions Bluetooth.

                  LOL. This different "official Google documentation" explicitly says "5 GHz Wi-Fi".

                  Edit: And this "Google documentation of unknown officialness" explains what goes over Bluetooth and what goes over Wi-Fi.

                  If you get wireless Android Auto working without Wi-Fi, I think people here would be interested in a report along those lines.

                    I tried to install Android Auto from the App Store but it doesn't work.
                    It says:
                    Unable to install Google Play Store, Google Play services, Android Auto.
                    What can I do?
                    Thank you

                      Fede Which build of GrapheneOS is the device running? What kind of device? Is that the exact text of the error message?

                        It's an Pixel 6 GOS with Android 15 build 2025031400.
                        It starts showing:

                        • Google Play Services: Do you want to install this app? Allow network permissions
                        • I click "install"
                        • Then the Android Auto window shows: Do you want to install the app? Allow network permissions
                        • I click "install"
                        • Google Play Store: Do you want to install this app? Allow network permissions
                        • I click "install"
                        • Installation failed
                          Unable to install Google PlayStore, Google Play Services, Android Auto:

                          Details:

                        What is "lukaspieper.gcam.services" ??

                          thanks! I'll look into it
