# When setting up 1337 it is stuck with a 3D GPS fix error message When you're stuck here then it means that the device has not seen enough satellites to get a valid gps signal. Your antenna needs to see clear sky and it can take up to 15 minutes to observe the signal.

To troubleshoot, goto and look at then antenna statusI

If it's anything other than OK then * Is the GPS antenna connected to the GPS jack? * Have you screwed in the cable as tight as possible? Sometimes then nut gets stuck midway. * Have you crossed antenna cables and they ended up in wrong jacks? That happens a lot with long cables and can be deceptive (planes might show up in the map but system is degraded). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
