9-inch Android Head Unit for Mazda BT50 2020–2023 by Polaris
If the factory head unit in your Mazda BT50 is starting to feel a bit dated, the Polaris 9-inch Android Head Unit gives you a more modern touchscreen interface without giving up the features you already use. Designed for the 2020–2023 Mazda BT50, it combines a 9-inch QLED display with wired and wireless Apple CarPlay and Android Auto, Bluetooth 5.0, built-in Wi-Fi and 4G SIM support.
The 1280 × 800 capacitive touchscreen provides a clear display for compatible apps, media and smartphone functions. You can also retain the factory camera, use steering wheel controls where applicable and connect additional cameras through the two camera inputs.
Audio is another strong part of the setup. The built-in MOSFET amplifier provides 4 × 50 W output, while the 13-band EQ, LPF/HPF crossover and subwoofer controls give you plenty of ways to adjust the sound to suit your setup. There’s also 128 GB of storage and 6 GB of RAM for the Android system and compatible applications.
