Pixel 2XL works great. I do have a 4XL but the aspect ratio is different and the extra processing power isn't necessary, though it will probably work fine. If you want to 3D print a custom mount, the design on the website is for a 2XL. Works fine with split screen.

I don't know exactly how it's done, that is just how the job was generally described to me, and of course I didn't want to risk doing it myself.

They did not give third party shops the ability to do this via toolbox. There is a loophole where one can manually update the gateway config directly via an ethernet cable to the MCU via a terminal. Tesla Rangers wouldn't know how to do this as they aren't trained in the procedure, if Tesla...

I found a shop that did the swap for me, and my understanding is they used the third party version of toolbox (as in the version Tesla allows non Tesla employees to use) to put the car in service mode, then updated the gateway configuration directly and redeployed firmware from Tesla. My avatar...

I retrofitted the lumbar which worked for a while before an update (gateway uses the vehicle config to figure out which modules to update, since passenger lumbar was not in original config, it doesn't get updated and the domain controllers ignore LIN messages from out of date devices)...

Sure, but the bumper was off anyway for the matrix lights.

Yes Yes, but toolbox was only used to put the car in service mode, as far as I can tell. Direct ethernet to the MCU to update the gateway configuration and trigger a firmware redeploy, which also updates all the modules including the passenger lumbar.

Service centers might have more privileges than rangers in the field.

OK, I got my passenger lumber reactivated. The Tesla Rangers don't appear to have sufficient privs to change the gateway configuration, so I would talk to Tesla independent service facilities if they offer this. My understanding is the toolbox that independents get access to can put the car in...
