Guidedragonpilot: Comma 2 Features and Updates
Comma 2 (C2) is an older device, and very few openpilot forks still support it. dragonpilot remains one of the last active options.
Current C2 Branch
The recommended legacy path for C2 users is the dragonpilot beta3 series.

What May Differ vs C3/C3X
Some newer features can be C3/C3X-only because of hardware requirements. C2 can still be very usable, but newer capabilities may be limited.
Hardware Comparison Callout
comma 3/3X has stronger processing hardware, newer camera stack, and better GPS performance than comma 2. If your C2 is working well with dragonpilot, that is still a good setup. Upgrading to a 3X gives you broader feature access and stronger long-term support coverage.
C2 Install Steps
- Factory reset and remove previous software first.
- Power on comma 2 and open the Choose Software screen.
- Select Custom Software and enter: smiskol.com/fork/dp/deprecated-beta3.
- Finish setup prompts and let the device reboot.
