I have a 2015 with the Nav/entune--how can you check the firmware of the Unit itself not the Apps, And what is the latest firmware for the head unit--I would like to get that updated to the latest if possible, but want to find out what Im running first?
**I always get unable to update software please try again later? WTH
Go to the Toyota download site to check for updates. To see what software you're running, from memory I think it's Apps>General> Software.
OK, is there something specific you need to do to install the KWI file to update the system OS?
I formatted a 16gig USB drive to FAT32, copied over the applicable KWI file, plugged it into the USB of my RAV4 2016 (premium entune). and Nothing happens. Went to the software update page and nothing happens and doesn't offer to upgrade.
Do I need a smaller drive? Are you suppose to plug it in before starting the car... or some other magic?
