The CNAV GPS week number is now represented as 13 bits, or 8192 weeks, and only repeats every 157.0 years, meaning the next return to zero won't occur until the year 2137
Interesting that the 787 has issues with this. GPS rollover was basically fixed the last time it happened in 1999

At 7:59 p.m. E.D.T. on Saturday, the New York City Wireless Network, or NYCWiN, went dark, waylaying numerous city tasks and functions, including the collection and transmission of information from some Police Department license plate readers.
The shutdown also interrupted the ability of the Department of Transportation to program traffic lights, and prevented agencies such as the sanitation and parks departments from staying connected with far-flung offices and work sites.
The culprit was a long-anticipated calendar reset of the centralized Global Positioning System, which connects to
devices and computer networks around the world.
