Tundra Nav System Firmware updates

Are there going to be any more firmware updates for the 2.5 gen Tundra's. I have a 2018 1794 edition Tundra and I was wondering of the 2021 nav firmware update would work with a 2018?

According the below website the 2018's have not been updated since Sept 2017

 

2021 radio is an entune 3.0, vs the 18s 2.0. I wouldn’t bet on the firmware being compatible.

 

I actually received an over the air update on my 2014 with non-JBL Entune with Nav this week. Didn’t notice anything different however.

 

I got it too and didn't notice a thing

I just used this post to get the latest firmware for my 2019 Tundra. There are different updates that are ota vs actually getting downloading online. My radio firmware I think was older than the truck.

 

Unfortunately, the files from the tacomaworld link did not work on my truck as those seem to be for 2019 & up Tundras. I was however able to update my system with firmware from Toyota's website that was released in 2017, the same as OP.

I guess pre-2019 Tundra no longer gets these kind of updates..
