"UPDATE ON THE STATUS OF YOUR GPS ON BOARD

The next GPS Week Number Rollover (WNRO) will take place on April 6, 2019. If you do not update your GPS before that date, it may be affected.

What are the consequences for you?
Your Carminat TomTom GPS will no longer update the position of your vehicle and navigation will no longer work.
Fortunately, we are providing you with a free update to correct this problem and ensure the continued operation of your GPS. "
