You could also try rooting your Samsung Galaxy S20 or S21 phone so that you can get the latest Android version. Another major thing to note, the app requires a working Internet connection as well to function correctly.

Few of the users have also reported that “Android Auto is not connecting to the car”. Google has collaborated with most of the industry-leading car manufacturers to make this a successful application. Since car manufacturers have to compromise some of the advanced features for cost-cutting reasons, not all car models have those hi-tech infotainment systems. That means Android Auto won’t connect to your car in case it is not compatible with the app.

Thus, in case you are receiving no response from your car while connecting, then you should check if your car model is compatible with Android Auto app or not. You can either choose to visit the Android Auto Webpage and run a compatibility test for your car. On the other hand, there should not be any such problems with some big names from the industry such as Audi, Cadillac, etc.

3. Check USB Cable

In case both your car and Samsung Galaxy S20/S21 are compatible with the app, there are a few chances that you are using the wrong hardware. If the Android Auto is not showing on the car screen, you might be using a faulty connecting USB cable or maybe a duplicate third-party cable. It is suggested that you only use the original connecting wire that comes along with your mobile phone.

The Android Auto app can also connect to your car wirelessly via the car receiver technology. One possible reason for why you are facing an Android Auto connection error is that you might have changed the stock car receiver system or Bluetooth system in your car. If you use an after-market system in your car, there are high chances that you will be facing Android Auto problems.

It is always advisable to stick to the original items so that you stay away from these kinds of issues and so that companies can troubleshoot systems for you by providing updates and fixes.
