If you're tired of dealing with wires every time you want to use Android Auto in your car, there’s a budget-friendly solution for you. While many modern cars support Android Auto, most require a wired connection, which can be cumbersome. The high cost of wireless Android Auto dongles, which can go upwards of Rs. 6,000, has left many car owners looking for more affordable alternatives. However, with a little bit of DIY spirit, you can turn your car's head unit into a wireless Android Auto powerhouse for less than Rs. 2,000 using a Raspberry Pi Zero W.
What You Need for the DIY Setup
The core of this DIY project is the Raspberry Pi Zero W, a small and affordable single-board computer with built-in Wi-Fi and Bluetooth. You can easily purchase it online from platforms like Amazon or other e-commerce portals. The Raspberry Pi Zero W typically costs around Rs. 1,240, making it an excellent choice for this low-cost project.
In addition to the Raspberry Pi Zero W, you'll need a micro SD card, an OEM micro USB cable, an SD card reader, and a heatsink-equipped cover for the Raspberry Pi to ensure smooth operation. Most of these items may already be lying around your home, which helps keep the total cost under Rs. 2,000.
Step-by-Step Setup Guide
Download the Image File: Head to GitHub and download the specific image file for the Raspberry Pi Zero W.
Flash the SD Card: Use a tool called BalenaEtcher to flash the downloaded image onto your SD card. This process will only take a couple of minutes.
Prepare the Raspberry Pi: Once the flashing process is complete, insert the SD card into the Raspberry Pi Zero W.
Set Up in Your Car: Plug your Android phone into your car's head unit using a USB cable to ensure Android Auto opens up on the display. After verifying, unplug the phone and connect the Raspberry Pi to the car's head unit using the same USB cable.
Connect Wirelessly: Wait for the green LED on the Raspberry Pi to glow, indicating it's ready. On your phone, pair with the "AndroidAuto-Dongle" via Bluetooth and connect to the corresponding Wi-Fi network. Voila! You now have wireless Android Auto running in your car.
