I bought a nexus 7 a month or so ago and I have never been able to get the GPS working.  Right after I bought it, I installed the 4.2.2 update.

I have "gps satellites" checked in the settings, and "wifi and mobile network location" unchecked.  I don't want to use mobile network location -- only the GPS. 

I installed a program called "satellite check" by ds software, but it can't locate any satellites.

Is my nexus broken?
