We will cover from the necessary hardware and software considerations to installation tips and potential pitfalls, we've got you covered.

Why Upgrade to Android 12 on Your BMW E90?

First, let's talk about why this upgrade is so appealing. Your BMW E90, while a fantastic car, likely has an outdated infotainment system. Upgrading to Android 12 offers a host of benefits:

  • Modern Interface: Say goodbye to clunky, outdated menus. Android 12 brings a sleek, intuitive interface that's a joy to use.
  • App Access: Imagine having Google Maps, Spotify, YouTube, and countless other apps right on your dashboard. Android 12 makes it possible, expanding your entertainment and navigation options.
  • Improved Performance: A modern Android system is snappier and more responsive than older systems, making every interaction smoother.
  • Customization: Android is all about customization. Personalize your home screen, widgets, and settings to create a system that perfectly suits your needs.
  • Regular Updates: Stay up-to-date with the latest features and security patches, ensuring your system remains secure and performs optimally.

For many E90 owners, the stock infotainment system feels like a relic. It might be slow, have limited features, and lack the smartphone integration we've all come to rely on. An Android 12 upgrade directly addresses these issues, providing a modern, feature-rich experience that enhances your driving pleasure. Plus, think about the resale value! A modernized infotainment system can make your E90 more attractive to potential buyers down the road. It's not just about having the latest tech; it's about making your car more enjoyable and valuable.

What You'll Need: Hardware and Software

Alright, let's get down to the nitty-gritty. To pull off this upgrade, you'll need a few key components. Don't worry; it's not rocket science, but it's essential to get the right gear.

Head Unit

The heart of your new system is the Android head unit. Look for one specifically designed for the BMW E90. These units come in various configurations, so consider the following:

  • Screen Size and Resolution: A larger, higher-resolution screen will significantly improve your viewing experience. Aim for at least a 9-inch screen with a resolution of 1280x720 or higher.
  • Processor and RAM: A faster processor and more RAM will ensure smooth performance. Look for a unit with at least a quad-core processor and 2GB of RAM. 4GB or more is even better.
  • Storage: You'll need enough storage for your apps, music, and other files. 32GB is a good starting point, but 64GB or 128GB will give you more breathing room.
  • Connectivity: Make sure the head unit supports Bluetooth, Wi-Fi, and GPS. Some units also offer support for 4G LTE.
  • Compatibility: Double-check that the head unit is compatible with your E90's specific model year and trim level. Some units may require additional adapters or modifications.

Choosing the right head unit is crucial. Read reviews, compare specifications, and don't be afraid to ask questions before making a purchase. A well-chosen head unit will provide a seamless and enjoyable Android experience.

Wiring Harness and Adapters

To connect the new head unit to your car's existing wiring, you'll need a wiring harness and potentially some adapters. A BMW E90-specific wiring harness will simplify the installation process and ensure that all your car's features, such as steering wheel controls and parking sensors, continue to work correctly.

  • CAN Bus Adapter: This adapter allows the head unit to communicate with your car's computer system, enabling features like steering wheel controls and vehicle information display.
  • Antenna Adapter: If your new head unit uses a different antenna connector than your car, you'll need an antenna adapter.
  • Backup Camera Adapter: If you have a backup camera, you may need an adapter to connect it to the new head unit.

Software and Firmware

Of course, you'll need the Android 12 software itself. Most Android head units come with Android pre-installed, but it's essential to ensure that it's a genuine and up-to-date version.

  • Firmware Updates: Check the manufacturer's website for firmware updates. These updates can improve performance, fix bugs, and add new features.
  • Compatible Apps: Not all Android apps are optimized for car head units. Research which apps work well and are safe to use while driving.

Having the right software and keeping it updated is just as important as having the right hardware. It ensures that your system runs smoothly and that you have access to the latest features and security updates.

Installation: Step-by-Step Guide

Now for the fun part: installing your Android 12 upgrade. This can be a DIY project if you're comfortable working with car electronics, but if you're not, it's best to leave it to a professional. This is a general overview; always refer to the specific instructions that come with your head unit.

  1. Preparation: Disconnect the negative terminal of your car battery. This is crucial for safety.
  2. Remove the Old Head Unit: Carefully remove the trim pieces surrounding the old head unit. Disconnect all the wiring harnesses and antenna cables.
  3. Connect the Wiring Harness: Connect the BMW E90-specific wiring harness to the car's wiring. Connect the CAN bus adapter and any other necessary adapters.
  4. Connect the New Head Unit: Connect the wiring harness to the new Android head unit. Connect the antenna cable and any other necessary cables.
  5. Test the System: Reconnect the car battery. Turn on the ignition and test the new head unit. Make sure all the features are working correctly, including the steering wheel controls, backup camera, and Bluetooth.
  6. Mount the Head Unit: Carefully mount the new head unit in the dashboard. Secure it with screws or clips.
  7. Reassemble the Trim: Reassemble the trim pieces around the head unit.
  8. Final Test: Do a final test to ensure everything is working correctly.

Potential Issues and Troubleshooting

Even with careful planning, you might encounter some issues during or after the installation. Here are a few common problems and how to troubleshoot them:

  • No Power: Double-check that the wiring harness is correctly connected and that the car battery is fully charged. Check the fuses in the car's fuse box.
  • Steering Wheel Controls Not Working: Make sure the CAN bus adapter is correctly connected and configured. Some adapters may require programming.
  • No Sound: Check the speaker connections. Make sure the head unit is not muted and that the volume is turned up.
  • GPS Not Working: Make sure the GPS antenna is properly connected and positioned. The GPS antenna needs a clear view of the sky.
  • Bluetooth Issues: Make sure Bluetooth is enabled on both the head unit and your phone. Try unpairing and re-pairing the devices.

If you encounter any problems you can't solve, consult the head unit's manual or contact the manufacturer's support team. There are also online forums and communities where you can find help from other E90 owners who have done this upgrade.

  • Customize Your Home Screen: Add widgets, change the wallpaper, and organize your apps to create a home screen that suits your needs.
  • Install Your Favorite Apps: Download apps from the Google Play Store, such as Google Maps, Spotify, YouTube, and Waze.
  • Use Voice Commands: Take advantage of Google Assistant to control your music, navigate, make calls, and send messages hands-free.
  • Connect to the Internet: Use Wi-Fi or a 4G LTE dongle to connect to the internet and access online services.
  • Explore Advanced Features: Some Android head units offer advanced features, such as support for Apple CarPlay, Android Auto, and digital TV.
