Map Updates for 2020 Toyota Hilux Revo

[Banana7]

Does anyone have any recommendations on how to update Toyota navigation system maps for a 2020 Hilux Revo? Since day 1, the maps didn't include changes in roadways in the last 3 years, around Pattaya and Bangkok. So now the maps are about 10 years old.  I am aware of google maps but they don't work well with internet and even with internet, they show weird routes sometimes.

 

I purchased a Garmin drivesmart 65 since there was a seller on Shoppe who claimed they had a Thailand map that worked in it. It worked sometimes but around Korat, Burriram etc. it certainly did not route correctly, always wanted me to go to Korat and then to my destination.

 

Does anyone manually update their Toyota maps?
