Will comma work with my car?

Type your car below. The exact model, year, and equipment decide the answer, not the badge.

334 listed configurations across 26 makes. First, what does comma do?

Small details matter

Same badge. Different requirements.

A model year, a driver-assist package, or a connector can change the answer. Support does not carry over from one version to the next.

Step 1

Exact match

Match the model year and the equipment package. Read every note on the listing.

Step 2

What it controls

Steering and speed are separate. A supported car does not get every feature.

Step 3

Current hardware

Confirm your car in comma's current list and pick the right harness before checkout.

Quick answers

Common questions

My car is not listed. Does that mean no?

It means support is not confirmed here. Check comma's current vehicle list before buying. Do not substitute a similar model or year.

Does Chestnut add support for my car?

No. Chestnut is a compute upgrade for comma four. It is not proof of support for an unlisted car.

What if my car already has adaptive cruise?

That alone is not enough. The exact model, year, package, and connection still need to match.

What about a community fork?

Fork support is checked separately for the exact car, device, and software version. A fork name does not guarantee compatibility.
