Installing Android 2din radio over Audio 20 - any experience with the wirings?

The allure of a modern infotainment system in your car is undeniable. Swapping out your factory-installed Audio 20 for a shiny new Android 2din radio promises navigation, multimedia, and connectivity upgrades. But the journey from stock sound to Android bliss isn't always smooth, especially when you start wrestling with the wiring harness. This article dives deep into the process of installing an Android 2din radio, focusing on the wiring challenges and offering practical advice based on real-world experiences.

Why Ditch the Audio 20 Anyway?

Let's be honest, the Audio 20, while functional, can feel a bit dated compared to the features modern Android head units offer. Here's a quick rundown of why people make the switch:

  • Navigation: Built-in GPS with real-time traffic updates beats relying on your phone.
  • Multimedia: Stream music, videos, and podcasts directly from your favorite apps.
  • Connectivity: Bluetooth for hands-free calling and music, plus USB ports for charging and media playback.
  • Customization: Android allows you to personalize the interface and install apps to suit your needs.
  • Reverse Camera Integration: A must-have for safer parking.

Gathering Your Arsenal: Tools and Materials

Before you even think about touching a wire, make sure you're properly equipped. Here's a checklist:

  • Android 2din Radio: Choose one that fits your car's dashboard and has the features you want. Read reviews and compare specs carefully.
  • Wiring Harness Adapter: This is the most crucial piece. It allows you to connect the new radio to your car's existing wiring without cutting any wires. Make sure you get one specifically designed for your car model and the Audio 20 system.
  • Dashboard Removal Tools: Plastic trim tools are essential to avoid scratching or damaging your dashboard.
  • Wire Strippers/Crimpers: For making secure connections if you need to splice any wires (though the harness adapter should minimize this).
  • Electrical Tape or Heat Shrink Tubing: For insulating connections.
  • Multimeter: For testing voltage and continuity (highly recommended).
  • Screwdrivers: Various sizes, including Phillips and flathead.
  • Patience: Seriously, this is key. Don't rush the process.

Step-by-Step: The Installation Process

Okay, let's get down to business. Remember to disconnect your car's battery before starting to avoid any electrical mishaps!

  1. Dashboard Disassembly: This is where those trim tools come in handy. Carefully pry off the trim pieces surrounding the Audio 20 unit. Consult your car's repair manual or online videos for specific instructions, as the process varies depending on the model. Be gentle and methodical.
  2. Removing the Audio 20: Once the trim is removed, you'll likely find screws holding the Audio 20 in place. Unscrew them and carefully pull the unit out. Disconnect the wiring harness and antenna cable from the back of the Audio 20.
  3. Connecting the Wiring Harness Adapter: This is where things can get tricky. The harness adapter should have two ends: one that plugs directly into your car's existing wiring harness and another that plugs into the back of the new Android radio. Carefully match the wires according to the instructions provided with the adapter. Usually, the wires are color-coded, but double-check to be sure.
  4. Wiring Challenges and Solutions:

    • Power (12V Constant & Switched): Make sure you have both a constant 12V power source (for memory) and a switched 12V power source (that turns on with the ignition). The adapter should handle this, but sometimes you might need to tap into an existing fuse or wire. Use a multimeter to verify the voltage and polarity.
    • Ground: A good, solid ground connection is essential. Connect the ground wire (usually black) to a metal part of the car's chassis.
    • Speakers: The adapter should connect to your car's speaker wires. Double-check the wiring diagram to ensure the correct speakers are connected to the correct outputs.
    • Antenna: Connect the antenna cable to the back of the new radio. You might need an adapter if the connectors are different.
    • Steering Wheel Controls: If you want to retain your steering wheel controls, you'll likely need a separate adapter. These adapters usually require some programming to map the buttons to the correct functions.
    • Reverse Camera: If you're installing a reverse camera, you'll need to connect the camera's power and signal wires to the appropriate wires on the radio and the reverse light circuit.
  5. Testing: Before you button everything up, connect the battery and test the radio. Make sure it powers on, the speakers work, the Bluetooth connects, and the navigation functions. Test all the features before proceeding.
  6. Mounting the Android Radio: Slide the Android radio into the dashboard opening and secure it with the screws.
  7. Reassembly: Carefully reassemble the dashboard trim pieces.
  8. Final Testing: Double-check that everything is working correctly.

Common Wiring Issues and How to Tackle Them

Wiring is often the biggest hurdle in this installation. Here's a breakdown of common problems and how to troubleshoot them:

  • No Power:

    • Check the fuses in your car's fuse box.
    • Verify that you have both constant and switched 12V power.
    • Ensure the ground connection is solid.
  • No Sound:

    • Double-check the speaker wiring.
    • Make sure the radio's volume is turned up.
    • Check the fader and balance settings.
    • Verify that the radio is outputting sound through the correct channels.
  • Steering Wheel Controls Not Working:

    • Ensure the steering wheel control adapter is properly connected and programmed.
    • Check the wiring connections between the adapter and the radio.
  • Reverse Camera Not Working:

    • Check the camera's power and signal wires.
    • Verify that the radio is configured to display the reverse camera image when the car is in reverse.

Real-World Experiences and Lessons Learned

Here are some insights from those who've tackled this project before:

  • "Buy the best wiring harness adapter you can afford. A cheap adapter can cause headaches and may not even work properly."
  • "Take pictures of everything before you start disconnecting wires. This will help you remember where everything goes."
  • "Don't be afraid to ask for help. There are plenty of online forums and communities where people can offer advice and support."
  • "If you're not comfortable working with electrical wiring, consider hiring a professional installer."
  • "Read the radio's manual thoroughly before you start. It will provide valuable information about the wiring connections and settings."

Frequently Asked Questions

  • Will this void my car's warranty? Possibly. Check your warranty terms. Modifications to the electrical system can sometimes void certain aspects of the warranty.
  • Do I need any special tools? Plastic trim tools are highly recommended to avoid damaging your dashboard. A multimeter is also very useful for troubleshooting wiring issues.
  • How long does the installation take? Plan for at least a few hours, especially if it's your first time. Rushing can lead to mistakes.
  • Can I install this myself if I have no experience? It's possible, but challenging. If you're not comfortable with electrical wiring, consider professional installation.
  • Where can I find a wiring diagram for my car? Your car's repair manual is the best source. Online forums and databases can also be helpful.

Conclusion

Installing an Android 2din radio in place of your Audio 20 can significantly enhance your driving experience. By carefully planning the process, gathering the right tools, and paying close attention to the wiring, you can achieve a successful installation. Remember, patience and attention to detail are your best friends in this project.
