I would love to try this out. But I’m assuming it requires a flash or something similar that would void warranty, correct? If so, it will certainly be nice if the dealership could program it in to maintain warranty in the future. I know I saw a post on the UC5 being capable for it before.
Nope. Nothing to void your warranty.
I am also running it now, thanks to
@Malodave. I am running it on a Comma 2, though, which doesn't have as complete support yet as the Comma 3.
On my truck, it does everything Dave mentioned EXCEPT it stops steering the truck whenever my speed is below 32 MPH. The ACC will still control the speed down to 0, it just doesn't steer itself below 32. An unexpected benefit is that it doesn't matter how long I am stopped, the truck will automatically resume now, when the car in front of me goes.
It is really awesome! I received the final parts that I needed (from Dave, actually) at lunch time last Friday. I installed it in less than an hour and went for a short test drive. It worked fine, so I loaded up and hit the road from SC to NJ. 700 miles and the Comma with OpenPilot made it so easy! I basically drove straight through.
The install is easy. The only tools you need are a 10mm socket wrench, a wide slotted screwdriver (or plastic body trim pry tool) and maybe a very, very thin slotted screwdriver or similar.
The thin screwdriver is only to help you pop out the trim piece directly above/behind the rearview mirror.
The wide screwdriver or panel tool is to pop off the big trim piece/housing that is behind the rearview mirror (the big piece that the little piece in the previous step snaps into). There's a slot to insert a tool at the front right corner, so you can insert the tool between the trim piece and the windshield and twist to get it started popping off.
The 10mm socket wrench is to loosen the two bolts under the hidey panels on the driver's side grab rail. With that loose, the trim that runs up the pillar from the dash to the roof is loose and lets you hide the Ethernet cable under it.
And that's it.
There's a power adapter that plugs into the OBD II port below the steering wheel. The Ethernet cable plugs into that and runs under the A pillar trim and across the top of the windshield and into the housing behind the rearview mirror. That powers the little black box that you put in there. The wiring harness plugs in inside that same housing, too. No cutting or splicing needed. And then a USB-C cable comes out of that same little black box and sticks out from the trim piece/housing to plug into the Comma to give it power and communication to the little black box.
The hardest part of it all is if you pop the mirror off its stalk. Popping it off is easy. Popping it back on is a giant pain. In my case, I pushed on it so hard, and I guess with a little side force, the stalk popped off the mount that it attaches to. I had to first pop the mirror back onto the ball on the end of the stalk and then pop the stalk back onto its mount against the windshield. No tools required for any of that. It just takes a lot of force at an awkward angle. And I was worried about reefing on the mirror enough to break it.
Even with all that, I was under an hour from start to finish and ready to drive.
I could take it all out in probably 10 minutes or so and you'd never know it had been there.
