r/Comma_ai

Any way to make this work with a 2025 f250? Tried doing some digging, but couldn't really find anything.

Look at the radio? Violation.

Look down? Violation.

Look straight ahead and sit still? Believe it or not, violation.

Instead of thinking about my surroundings and how not to hit them, I'm now thinking about how to look like I'm looking and even then it still goes off--sitting still, looking straight ahead with my eyes as wide as I can make them. It is so distracting being pinged to TAKE OVER IMMEDIATELY every minute or so.

I am sad at what using open pilot has become. I hope it changes. I would not recommend this system to anyone anymore as it is right now.

Title. I’ll be driving a lot for work, a comma compatibility and experience is important for me. Which of the above models provides a superior comma experience?

As the title mentioned, do you expect comma 4 to go on sale on the 4th of July or only during black Friday?

I understand that there's a master list, but I also understand that there's cars that aren't listed that also work. I also understand that there's a discord, but there's so much information there and somebody asks something and then nobody answers them.

Can someone point me in like the specific link or website where it'll tell me if this will work? If there is, is there a specific procedure to get this to work? Do I need to install specific stuff? I am tech savvy and I like to figure stuff out. If someone can point me in the direct direction. I already have the discord but I asked there and nobody answered me.

I'm trying to install a comma 4 on a 2026 Honda pilot. The moment I plug in the USB c power cable from the harness to the comma ai device, I get lane assist not available and a bunch of other warnings. Comma doesn't power on too. If I unplug the USB c cable, all assistance features work fine with just the harness. Has anyone else faced this issue?

EDIT: Brilliant me used the wrong power port on the comma device. It powers on now but still getting warnings

EDIT 2: all working after correct power slot and a restart

Been using Sunnypilot CD210 on my 2022 KIA EV6 GT-Line w/Comma 4 for about a week now.

Pros

• Does surprisingly well on twisty rural roads with dips; seems better than stock SunnyPilot
• Very good at lane changes
• Excellent performance on highways

Cons

• Oversteers on turns unless it's a perfect 90 degree angle with few other variables to account for
• Doesn't seem to do well with adjusting to other cars' speeds at far out distance (likely due to camera limitations?)
• Noticeable ping-ponging at under 10 MPH
• Can't get it to slow down at lights or stop signs

Curious to know what everyone else is using these days.

I don't know about the rest of you, but I went from the comma three to the comma four and I actually noticed my truck is ping-ponging back and forth more than ever. It also seems to slow down around corners or randomly at times in a way it never has before and chime like crazy thinking I'm not looking forward even though I am as if it can't see me very well.

Is anyone else having these same issues?

I thought it was a fluke the first time, but it's definitely a feature. In my 2019 RAV4 Hybrid, if I pick up my phone, it switches the car into Trail Mode, which disables self-driving. I can't turn it on again until I switch out of Trail Mode. I don't really mind it, and it's kind of an interesting reminder to not use my phone when I'm driving. It's certainly more gentle than disabling it and not allowing it to be used until a restart happens, which has happened in the past. Anyone else notice this?

Has anyone played around with using a comma on a lucid? We have 2 comma 3xs and after 2 accidents in which the commas dashcam feed has made insurance liability super easy its hard to find a comparable dashcam with cloud backup that we like.

So we were considering getting a comma 4 and hooking it up for dash cam purposes only, is this something comma supports? I know lucid isnt a supported vehicle for adas which isnt something we need but the dash cam ease and implementation is top notch to us.

Any help is appreciated!

Possibly stupid question. I have a Kia EV6 that I'm about to pull the trigger on a comma 4. I found out about OVMS recently and would like to be able to have an open system to replace the Kia subscription to start my HVAC over wifi and lock / unlock my doors. (kia helpfully put these featured behind the higher priced tiers).

I remember that some branchs of openpilot offer these features, or am I nuts here?

Edit for more info: 2023 Kia EV6 Wind RWD Long range with HDA (not HDA2). Made sure I was compatible with Comma when I got the car. I'm just curious here if Comma handles the core functions I'm interested in with OVMS or not.

Wondering if someone can help. I have a comma 4 that I moved from my 2022 Ioniq 5 to my newly purchased 2026 EV9 GT-Line using the recommended Hyundai R harness.

From my research, there is a branch of Sunnypilot that's supposed to work with angle steering vehicles like the EV9. I've tried two of the hkg angle steering branches and both ones the comma 4 states the vehicle is unrecognized. Can someone tell me exactly what branch url to install? I was previously using staging or dev with my Ioniq 5 Ultimate

My Comma arrived today for an 2025 Accord Hybrid. I think I know what I need to do to install it but are there any videos that walk through exactly what I need to pop to get to the camera and suggestions on how to route the wires?

I'm in the market for a new car, and I'd really like to get a Lexus ES. The 2026 is the only version with self-parking, but it doesn't seem to be compatible with Comma AI. The 2019-2025 are. What do you guys think I should do?

a: buy a 2026 and assume it's just a matter of time before Comma AI is compatible with Lexus ES 2026.

or b: Buy a 2025 to secure Comma AI compatibility, and suck it up and have no self-parking?

Thanks everyone for the help.

Now that we’re coming closer to actual summer heat, when I get to my car, often times it shows up a message saying that the device is overheated due to sitting under the sun.
It does start working after maybe a minute or so with the ac blasting, but I’m worried about how just leaving it on the windshield cooking could potentially just destroy it.

I was wondering if people tend to just remove it and store it elsewhere when they leave or not, I don’t honk just disconnect it and leave it in the glove box or something helps that much but the direct sun in it sure makes it heat up even more.

I’m kind of afraid that the usb connector may get faulty with constant connect and disconnect, I’ve been doing that for a like a month when I first got it because I was developing stuff for it, the usb connector doesn’t seem great for constant removal.
