got the same, i get C2-13396-2 when i try to get my location in the Map app.
and Near says that it can get my position data.
i got the vita with 3g and i live in Norway, i tried with the simcard from my cellphone.
We have had a troubleshooting suggestion to try and solve this issue. As the Near app is saved directly to the system you cannot refresh it. If you restore the PS Vita system then this should refresh the app and hopefully resolve the issue.
A guide to restoring the PS Vita system can be found here
The restore should not delete the contents of your memory card but I would remove it just to be sure.
Please let me know how you get on and I can feedback if the solution does not work.
