Yeah, I'm going with bad comma3x. I've had it up and running for almost a year with little to no issues until recently. I originally had a modified (extended with resistors) Ford Q4 harness. Bought a new harness and lightning adapter to eliminate that. So I have all new everything except the comma3x itself, which was bought on black friday last year.
Suppose Ill get a support ticket with them started.
I was having a similar problem. I turned the lightning adapter end to end and same thing. But when I kept the lightning adapter ends the same then flipped it over, all my problems went away.

I flipped the cable at the adapter numerous times to no avail, flipped the cable at the harness? Success!

With a short cable you don’t need a coupler

The lightning coupler is marked for orientation. Comma goes towards the device and the lightning bolt goes to the truck. The most you should have to do is flip your cable once at either end.

Is anyone gonna talk about the fact that you can't buy a new comma 3x anymore, and that comma 4 will possibly bring new problems? Just asking from the point of view of someone who bought everything including harness, coupler, mirror mount, but the Comma it self. lol

Is it confirmed you can't buy a 3X anymore?

From a standpoint of getting installed and running, you are okay. It is the same chipset and runs the same harness. The mount obviously will not work. If you bought the mount from me, I can do a return for you.

From a software standpoint, BluePilot will not run on the C4 until we get the new logic for the smaller UI integrated, which I'm not sure if Comma has even published that code yet.

supposedly it's the same chipset just a smaller form factor, if they shrank the dies I may be interested since in theory it means less power, less power, runs cooler. I work nights and my truck is in the open sun in the south, so by the time I'm ready to ride I have to wait for my comma to cool

That's why I sell a sliding dock. Take it off the window, put it in the console. It takes about 45 seconds to boot up when you put it back, but no waiting for it to cool.

Comma.ai no longer sells the 3X directly. On their website as of today you can only buy comma 4.

Good idea, I just use it as theft deterrent. I mean I could bring it inside and do it but I leave it running to download all of my drives when I pull in.

Well okay then. Konik is still selling the A1M if you prefer a full sized device with screen. The A1M has a built in quick mount, so it sounds like either way you don't need your dock. Send me a DM if you want a return.

I actually have a base for inside the house that mounts under a shelf, and you can power it with a USB-C power brick. Send me a DM if you want one. That's how i upload all my routes.

I didn't buy your dock, I 3D printed the older sliding model that mounts with a screw in the mirror. I still think I can use it because the sliding part has a surface that parhaps can be used to attach the comma with a double sided tape. But I'm waiting on someone's review of a comma 4.

I noticed the markings on the lightning adapter and have it installed the correct way. I did try flipping the usb cable at the adapter and noticed a different error on my comma.
Ive installed default openpilot for troubleshooting with comma support, but the difference is:
with the usb oriented one way, I cant get past dashcam mode and,
with the usb oriented the other way, the comma will get past the dashcam mode briefly, then i get the "CAN Bus disconnected" error.
just waiting to hear back from support for now.

The dev who does all of the UI work on BluePilot is not in a position to buy a Comma 4. If anyone is interested in chipping in to buy him one so he can develop the port of BluePilot, please send me a DM. We have about over half the cost committed already, and we won't actually collect any funds until the purchase is made.
