01 · Match your exact car

Check make, model, year, trim and required driver-assistance package. Read the listing’s speed-control and steering limitations before buying hardware. An unlisted configuration needs investigation, not a guess.

02 · Get the matching hardware

Choose a compatible comma device and the harness specified for the car. Check the current shop contents and any additional parts in the vehicle listing. Do not assume a cable for a similar car is interchangeable.

03 · Mount and connect while parked

Follow comma’s illustrated hardware instructions for placement, camera visibility, cable routing and the vehicle connection. Use our setup hub to find the right guide for your hardware.

04 · Install, calibrate, learn

Follow the maintained installation guide for your chosen software and device. Complete the on-device introduction and calibration, then learn the engagement and takeover controls. For a first setup, standard openpilot is a straightforward starting point; explore community options afterward.

Questions

Do I have to code or use a terminal?

The normal consumer setup uses the device’s installation flow. Our guides link to the maintained instructions; you do not need to compile openpilot yourself.

Where is the install URL?

Use the linked openpilot installation guide to get the checked URL for your device. Keeping it there avoids an outdated installer in this introduction.
