Grundig M5 2042 15104239 Use and care manual

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 6th 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.
Irregularities that occur due to the WNRO, could be solved by performing this
firmware update.
Unfortunately, not all Grundig navigation systems can get a new firmware update.
This firmware update is suitable for the
Grundig M6, M8 and M10
