2019 SR% Navigation question

[BearBio]

Heading down south into the SW (Cali, Nev, Az). Want to upgrade my Navigation maps (2019 Toyota SR5 Premium). All the chips on Amazon and elsewhere say 2016 to 2018. Part Numbers: 86271 OEO77 or 86271 OEO76.

Has anyone firsthand knowledge as to (1) will one of these work and (2) if so, which one will work (?)?

I did upgrade a year or so ago with a new SD.

Last couple of trips to the Yakama REZ, we had issues with the Navigation. Anybody know how to update on a 2019 SR5??

Went to Toyota OEM Parts. Had to try a couple of sites but found the part number ($150 to $300 ) Installed: $350-$400!! Found the same part with a 4.5-star rating on Amazon for~$20 (same upgrade I bought a couple of years ago). Bonus: date of maps was as of April, 2025!

Had the flu for a couple of weeks. Another day or so to get my strength back and I'll install it!
