3B 07 80 40 02 1F 0C 00 ED # 31/12/2020
Year Limitation
The only trick is specifying Year as the input is limited to YY, e.g. 15 represents 2015.
This begs the question, with an input of 25, is that 1925, or 2025?
Fortunately we need not worry about this for many decades as the navigation OS software (4-1/00) defaults to years 1993 to 2092.
| Input | Year |
|---|---|
00..92 |
2000..2092 |
93..99 |
1993..1999 |
