What are all the functions of the DexNav?

Also how can I use it to its full potential?

The DexNav’s main function is to give information about the wild Pokémon in the area, but this information can be viewed and used in different ways. You can use the DexNav to its fullest potential in a variety of ways, but I think Shiny Hunting is the most prevalent, explained in the following list. Here are the DexNav’s main functions:

A chain builds every time the player captures or defeats a hidden Pokémon of any species. If the player does not capture or defeat the Pokémon (whether the player chooses or is forced to flee, such as by Roar, or the Pokémon escapes, such as by Teleport), the chain breaks. A chain will also break if, outside of battle, a hidden Pokémon appeared and is not encountered (whether by scaring it away, waiting too long, walking too far away, leaving the area, or entering a different battle). The chained Pokémon do not need to be found using the Search function, and the message “The Pokémon couldn’t be found. Try looking in a different area!” does not break the chain if received when the Search function is used.

Hope I helped!
