    If you have an older GPS device, brace yourself for the possibility that April 6th will be the last day it works.

    Older units measured week numbers using a binary system with 10 numeric places: which means Week 1,023 is the last week before it rolls over to zero. Week 1,024 starts April 7th... and many devices will think it's 1980 again.

    Accurate time is crucial with GPS, as triangulation from the GPS satellites is based on how long a synchronized signal takes to reach the device from each satellite. By measuring the delay from satellites in known positions, the device can calculate its location on earth to within a few meters. If the GPS device's sense of time is messed up because the week number reset to zero, nothing is going to synchronize accurately.

    Besides - at this point, your phone should have GPS; a good navigation app should replace any dedicated GPS device you have.

    They'll run out of room to store the date, so kind of similar to Y2K.

    One article said if the GPS is less then 10 years old it should still work, older devices might not if they haven't been updated.
