Navio 2 ardupilot firmware update

hi, i am confused about navio 2 update in the forum, there are those who say it can be done with this command only (sudo apt-get update && sudo apt-get dist-upgrade ) or there are those who suggest it system ( rpiboot-navio2 /8461/28?u=mlebret)
My question is: What is the latest version I can currently use on Navio 2 and how can I do this update without losing my calibration settings? Thanks in advance for the answers.

Hi @res,

You can update your image with the following command:

sudo apt update && sudo apt dist-upgrade

The other way is to reflash the SD card with this image but it will erase all the previous settings.
