Do you mind posting a pic of your invoice showing the work they did (not including your private information of course)
I'm curious to know if the computer would also be replaced on a car like mine - June 2016 build with AP1.
As mentioned in the other reply, I believe kits are only available for AP2.0 and AP2.5 cars. For what its worth, the part number quoted for my AP2.5 card was
MCU INTEL HW3 UPGRADE-For TegraAP2.5- NA Part #: 9874561-00-A
There is another part number for the AP2.0 cars. I think the harness might be different. I made the appointment just over a week ago and my appointment was yesterday, so there appears to be no shortage of the part. There probably will be now, now that the price is reduced!
I've picked it up and everything is as expected. It's nice to have a working browser and zippy screen navigation, etc. I don't have FSD, but the EAP autopilot appears smoother with HW3 (though it could also be newer software). Speed limit signs are shown as well. The LTE radio also appears better than my old one. The loaner I got had an MCU 2, so I already had a taste of it before I picked mine up. No issues with dark backup camera or anything. They were able to back up all my settings except for Web favorites, and my saved Wifi. My Homelink devices were still there but didn't work and I had to re-program them again. The only issue I have, and this may not be related to the HW upgrade, is that the brightness of the drivers display is darker than the main console. This appears to be a 2020.48.30 issue, as the loaner I had had the same issue. In night mode, I think it's too dim. And if you increase the brightness, then the main console is too bright. Hopefully they can address that with a software upgrade.
For AP2.0 or AP2.5 owners, I can certainly recommend the upgrade, especially at $1500. It includes the latest current Autopilot computer, so it really is a bargain even if you didn't buy FSD (yet). Now, if they do have a pay-per-use FSD option, at least your car can use it.
FYI, the car details now reports the Autopilot computer as 'Full Self Driving', not HW3. It used to say '2.5 Computer'. And the Infotainment processor is now reported as 'Intel' instead of 'Nvidia Tegra'
