Review on Enhance Your Toyota Navigation System with Latest 2020 MAP on SD Card 86271-0E072 by Abdalla Galloway

Firstly, you most likely will not get an OEM SD card. It said; I followed the instructions (I didn't google first, you should). I put the card in the SD slot and started the car. The system recognized the update and started the process. While this was happening my card and system were working but the colors were messed up and some things were missing. Look, just let it do its thing. At the end (e.g. after 5-8 minutes) a message will appear on the screen indicating that the update is ready. Turn off the car restart and it should prompt you to install the update (this can also be done from the settings menu). Say yes and let him do his thing again. When everything was done, my display went back to normal and all my functions were back. I did a quick test the next day and everything worked fine. Not sure how much I won but this card is 4-5 years newer for cheap money.
