This is what’s believed to have happened in September when an Android Auto did exactly the opposite of the things we mentioned above. So the new Android Auto version ended up doing more than good, with users reporting on Google’s forums that the app no longer works.
More specifically, Android Auto can no longer pair with the car, as the mobile device is not recognized after installing the update.
These users claim everything was working just fine before installing the update, so the new version is the one they blame for the whole thing.
At this point, however, these problems seem to be rather isolated, though someone says they came across plenty of other reports in this regard. But right now, Google doesn’t seem to be investigating these problems, especially because they don’t appear to be very widespread.
On the other hand, if these users are 100 percent sure the September update is one causing the problems in the cars, the fix is quite simple: just downgrade to an earlier version of the app, and the error should be gone.
At the same time, they should just update to Android Auto 7, which was released earlier this month for production devices and is now rolling out via the Google Play Store to phones across the world.
Google, on the other hand, says on the forums that connection issues can be encountered due to various reasons, so figuring out what exactly went wrong could end up becoming your own mission. It remains to be seen, however, if other users encountered the same problem after the September update.
