So, I check the download page for the radio firmware every couple of months and there was an update in June and I had no problem applying that to my 2017 Highlander Limited Platinum with navigation. I checked today and the download page shows a "new" update with a release of September 8th. When I go to download it the file looks like it is named the same as the June file, at first I thought this was odd but maybe a Toyota thing so the radio wouldn't take the wrong firmware. When I put the usb drive in the car and go to update it recognizes that there is a usb attached, I have tried a couple different usb drives, and when I go to setup>general>software update, it doesn't recognize that there is a new update on usb drive (I think last time it popped up and said hey new software). So is this the same file and they changed the release date? Did they upload or link to the wrong file? Am I doing it wrong? Any help would be appreciated. Thanks in advance.
