WEEK NUMBER ROLLOVER - FIRMWARE UPDATE
Due to the "Week Number Rollover" (WNRO) it is possible that the Grundig navigation
system shows a different date after the 6
th
of April. Occasionally it can also happen
that other irregularities (will) occur.
The WNRO takes place once every 19 years. The rollover is a result of the internal
satellite storage numerator. The numerator of these satellites jumps back to zero
after every 19.7 years.
