Although installing Android Auto in your car may sound like a daunting task, with the right guidance and tools, it can be a straightforward and fun process.

Hardware and Software Required

Before starting with the installation process, you will need to check if your car’s head unit is compatible with Android Auto. Most aftermarket head units support Android Auto, but OEM (original equipment manufacturer) versions may not. If you have an aftermarket head unit, make sure that it is Android Auto compatible before purchasing any additional hardware.

The hardware you will require to install Android Auto in your car includes:

  • An Android Auto compatible head unit
  • Appropriate cables and connectors
  • USB port

The software required includes the Android Auto app, which you can download for free from the Google Play Store.

Step-by-Step Installation Process

  1. The first step is to turn off your car’s engine and disconnect the negative terminal of your car’s battery. This step is crucial to prevent any electrical hazards while you are working on your car’s audio system.

  2. Plug the Android Auto compatible head unit into the car’s wiring harness. Ensure that the wiring is connected correctly and securely. You can consult the car’s manual or seek professional help if you are unsure about the wiring.

  3. Connect the head unit to the car’s USB port using an appropriate cable. It is essential to use a high-quality cable to prevent any data transfer issues.

  4. Turn on your car’s engine and head unit. Your head unit should automatically detect the Android Auto app. If it does not, check if the USB cable and app are working correctly.

  5. You will need to enable Android Auto on your phone before using it in your car. To enable Android Auto on your phone, go to "Settings," select "Connected devices," and turn on the toggle switch on Android Auto.

  6. Next, on your phone, open the Android Auto app and follow the on-screen instructions to complete the setup process.

  7. Once you have completed the above steps, your Android Auto is ready for use. Congratulations! Your 2007 Subaru Legacy now has an updated audio system ready to connect your devices and enjoy your favorite music and apps safely while driving.
