Firmware Updates

How do you check if you need a Firmware update? (2021 3.0 Premium)


Also, Do you have to take the car to the dealer, or can you update via USB?

Thanks for any help!!

Great question!!

Toyota emailed me and said I needed a Firmware upgrade

I’m at the dealer now and they seem as confused as me!

Update...dealer was on the phone with Toyota for an hour...they walked the Tech through the steps to update the firmware only to find out that it didn't need one.

Oh well, I live 70 miles from the dealer so the drive there and back was fun! LOL!
