The new Nexus 7 (2013) device has a defect where the GPS will lose the location fix after a period time, usually about 30 minutes to an hour, and cannot be restored without a shutdown/restart cycle, but the problem remains. Apparently, this applies to all new Nexus 7 (2013) devices and Google has not provided an ETA of a fix. Check the following links for users with this problem, even after returning N7, the new N7 tablets they've received also have the same problem.
I really like my new N7 but this GPS problem is very aggravating.
