Helm Commander
For GM Purpose-built for GM CAN-bus vehicles
More than just a Display.
A 7-inch performance dash built for GM CAN-bus vehicles & Conversions — it reads the bus in real time to tune, log, diagnose. No laptop required.
Instant-on
Loaded and talking to your bus the moment the screen is on.
No operating system to boot, nothing to corrupt when you cut the power — where a Raspberry-Pi-based dash spends tens of seconds loading Linux, Helm Commander is already reading the engine. How it's built →
The command centre
