Entune Update vs. Audio Software Update

I went to that link and input my VIN. Pressed Go and nothing happened. Tried just inputting my make, year and "with navigation" (i.e. no VIN) and received a file dated September 8, 2017 "13TDANNA-DA11_0146.kwi". From another thread, I found that the most up-to-date firmware for my truck is actually "13TDANNA-DA11_0164.kwi"
Thanks for providing the official Toyota link @justcuz but it appears that Toyota serves old updates at that page (at least for my year model truck).

here is Canadian update link

 

First and foremost, I am NOT tech savvy!! I have tried to update my software to no avail. I downloaded the update provided by the Toyota site using my VIN number onto a flash drive. File name is 13TDDANA-DA10_0010.kwi When I click on update on my radio, the next screen doesn’t allow me to update it. It’s as if there’s nothing on the drive or my radio doesn’t recognize it. Any help would be appreciated. I’m tired of dropping calls!! I have the non JBL head unit. Thank You!
