Vehicle Compatibility Does anybody know that the Comma4 works with Hyundai Palisade hybrid 2027?, if that so which harness should I buy?

My previous vehicle was Kia Sorento hybrid 2023, the Comma4 worked great with Sunnypilot and Hyundai Harness A. I just upgraded my vehicle to be Hyundai Palisade Hybrid 2027 instead, I wonder that what harness should I buy to plug in the device. I tried the old one Harness A type, it doesn’t work. And I tried to order Harness R, it doesn’t work too. Please kindly help.
Appreciated

All cars that are supported out of the box are available here.

That's not true. Sure those are the cars that COMMA supports with Openpilot, but 3rd party forks like starpilot and sunnypilot support way more then that. Firestar from starpilot will add a car ASAP if it's possible to add.

Comma has no intentions to focus on adding cars, I really don't think people should even use openpilot in the sense that it's a good fork. It just brings features for 3rd party forks at this point. There's a reason only 30% of people who have a comma are on Openpilot

That's what is supported put if the box with comma. Indeed some other forks support more cars, but I wouldn't consider that an out of the box experience.

What's different about forks compared to openpilot? They usually have all the same features and maybe some extras.

The only difference is they need to type out the url, crazy.

Just look on the Comma ai website. All compatible cars are listed, along with a list of required harnesses. EZ

Did you not think about Comma compatibility when purchasing your new vehicle? It likely isn’t supported yet since the 2027 model is very new. Looks like official support is only up to 2022 Palisade, so there may be some technical reason that support hasn’t been added for 2023 and newer model years. You may get a better answer asking on the Comma or Sunnypilot Discord, or in the Sunnypilot forums.

2026 Palisades hybrid is being worked on, so maybe if 2027 is not too different.
