Setup Guide

Install OverDrive on Your Car

A two-part walkthrough — enable ADB on the head unit, then sideload the APK from your phone. No PC required.

Part 1

Enable ADB on Your Car

Dialer method — works without a USB cable.

  1. 1
    Pair Bluetooth

    Connect your phone to the car via Bluetooth. The dialer code only fires when a paired phone is present.

  2. 2
    Open the engineering menu

    In the car's Phone app, dial:

    *#91532547#* Include the trailing *
  3. 3
    Generate & enter the unlock code

    The car shows your IMEI and a Chinese prompt. Copy the IMEI, then on your phone visit:

    ahmada3mar.github.io/BYD

    Paste the IMEI to generate a code. Enter that code into the car's text field, then tap 进入 (Enter).

  4. 4
    Turn on Debug switches

    From the engineering menu open TestTools, scroll down, and enable both:

    • Debug mode when USB connected
    • Wireless adb debug switch
  5. 5
    Find the car's IP address

    Connect the car to your phone's hotspot. Then on the head unit go to Settings → WLAN, tap your hotspot connection, press the info icon, and write down the IP.

    You'll need this IP in Part 2 — keep it handy.
Part 2

Sideload the OverDrive APK

Push the APK from your phone using Termux + adb.

  1. 1
    Update Termux packages

    Open Termux on your phone and run:

    pkg update && pkg upgrade -y
  2. 2
    Install the Android tools
    pkg install android-tools -y

    Grant storage permission when prompted — Termux needs it to reach your downloads folder.

  3. 3
    Connect to the car over ADB

    Replace <car_ip> with the address you wrote down in Part 1:

    adb connect <car_ip>:5555
  4. 4
    Locate the APK

    Move into the folder where you saved the APK on your phone:

    cd ~/storage/downloads/your_apk_folder
  5. 5
    Install OverDrive
    adb install overdrive.apk

    Replace overdrive.apk with the exact filename you downloaded. Once Termux prints Success, the app appears in the car's launcher.

    Done — open OverDrive on the head unit and complete first-launch setup.

Everything Your BYD Needs

Built specifically for BYD vehicles with deep system integration

Optimized Recording Pipeline

State-of-the-art architecture designed for efficiency. Our optimized pipeline keeps CPU usage minimal while delivering smooth, high-quality recordings.

<28% CPU Usage
~150MB Memory
<3s Boot Time
Market First

Proximity Recording

Uses BYD's 8 parking radar sensors to detect approaching objects. Records pre/post event clips only when something gets close — saving storage and resources.

  • Configurable trigger levels (Yellow/Red)
  • Pre-event buffer (captures before trigger)
  • Post-event duration (configurable)
  • 500ms debouncing to prevent false triggers

Real-time Performance Monitor

Dedicated dashboard showing CPU, GPU, memory usage, and battery voltage. Know exactly what resources your system is using.

17 Languages

Speaks Your Language

Full UI translation across 17 languages with automatic system-locale detection. SRT subtitle sidecars on every recording, localized to your active language.

  • Auto-detects from system locale on first launch
  • Native-script picker — no flags, no compromises
  • Localized SRT sidecars next to every .mp4
  • Server messages, errors, and overlays — all translated

Advanced Sentry Mode

24/7 surveillance with motion detection and AI object recognition. Keeps your vehicle protected while parked.

ISP Blocklist Bypass

Browse internet via BYD's built-in SIM card, bypassing ISP restrictions. No dedicated WiFi hotspot needed. Optional paid feature as server costs grow.

ADB Shell Runner

Built-in terminal for developers. Run shell commands, check process status, view logs, and debug directly from the app.
