At Nutz N Voltz / Promethean Batteries Inc., we believe that electric vehicles deserve a second life. That’s why we’re working on an open-source customizable, upgradable infotainment and control system for the Chevy Volt.

We now have a public GitHub repo where you can explore, contribute, and build on the software side of this project:

What’s Included Right Now

The front half of Monroe’s software is already open source, focusing on displays, integration, and automation:

  • AAOS (Android Automotive OS) integration
  • VCX SE Pro gateway support
  • Comma 2 Autodrive with Ardupilot for redundant safety monitoring

There’s also a simple, low-cost way to take control of the Volt’s center display by using pins 6 and 12 on the Volt HMI to input a composite signal (backup camera input). With a basic mechanical switch, you can toggle between the stock backup camera and the new AAOS-driven display.

Hardware Setup

For those eager to dive in, the starter kit costs around $250 in hardware:

  • Khadas VIM3 Pro
  • VCX SE Pro (connected to the passenger-side secondary DLC for access to the right CAN bus signals)

This setup allows you to:

  • Drive the stock display (or replace it later with HDMI displays)
  • Add touch overlays, keyboards, or mice for full interactivity
  • Run customizable AAOS apps for climate control, radio, navigation, CarPlay, and more


Why This Matters

Traditional solutions require $300–500 LVDS switch boxes. Our approach uses the existing composite input, making it much cheaper and open to further development. As the project evolves, both the dash and center console displays will be fully app-driven, customizable, and future-proof.

The VIM3 Pro’s M.2 slot even supports 5G modems, enabling on-board apps for phone, internet, maps, and a self-hosted OnStar alternative.

What’s Next

Later this year, Monroe plans to release open-source work on the electric motor controllers, transmission, and drivetrain—a huge leap forward in extending the life and performance of the Chevy Volt.
