You might have missed something in 1999, while everyone focused on the other Y2K bug, which was older GPS devices going haywire. This was because the date is stored as a 10 bit character which means that 1024 weeks after the start of the epoch, the dates on your GPS device rolls back to 0 and it is no longer able to give positional data as it depends on knowing when, as well as where you are.
On April 6th, this will happen once again and far more people are bound to notice than when this previously occurred. There are ways to ensure that devices do not suffer this bothersome 10 bit problem but with the lack of news coverage and general awareness not many have bothered. Devices which adhere to the ICD-200/IS-GPS-200 specification will have no problems whatsoever; but many devices did not originally and when was the last time you saw a firmware update for the GPS in your car?
"Older satnavs and such devices won't be able to use America's Global Positioning System properly after April 6 unless they've been suitably updated or designed to handle a looming epoch rollover."

Google’s new Nexus 7 was released in July with updated hardware and Android 4.3. One of the changes to the platform was the switch from the original Nexus 7’s Tegra 3 processor for a quad core Qualcomm Snapdragon S4 Pro SoC. Qualcomm also built the GPS (and GLONASS) unit. Unfortunately, some users ran into issues with the GPS and touchscreen on the updated Nexus 7 due to software bugs.
In response, Google is rolling out an Over The Air (OTA) update to all new Nexus 7 devices. Among other minor bug fixes, the JSS15Q update resolves the GPS and multi-touch issues. Previously, the GPS would randomly drop the connection and a smaller number of users reported that touching the screen would initiate screen presses at multiple (unintended) areas of the screen on a shared axis from the actual touch point.
AnandTech reports that the JSS15Q update, which is being slowly rolled out to all of the 2013 edition Nexus 7 devices, has resolved the GPS issue. The XDA Developers site further reports that the update addresses the mult-itouch and user data eMMC corruption bugs.
Nexus 7 users can either wait for the JSS15Q update or flash the device with an updated Google-provided ROM.
