Find navigation map year by software version
 

I bought a used car Honda Odyssey 2012 and the dashboard System/Device information for Navigation displays:
Database: USA & Canada Version IT003.02.01
Software: Version 1.20.0300

How do I tell which Navigation map year is the above related to?
Before I update the navigation software to the latest year, I would like to find out the current installed navigation map year. I called https://hondanavi.navigation.com/ but they could only tell for maps available from the year 2016.

Regards
