By default, some new Android devices have the Development settings hidden, which is where the Mock Locations setting is at. Without enabling Mock Locations, you can't successfully use the GPSInfo for Android app to use your BT-368, BT-359, BT-821 or any other GlobalSat Bluetooth GPS with an Android Tablet or Smartphone.
Here's a video that shows you how to display/enable Developer settings on Android devices: https://www.youtube.com/watch?v=XaiWw7XmsuU
Once enabled, you can find the Mock Locations settings within that menu.
Then you can continue to follow the steps in our Android Bluetooth Setup Guide: http://www.usglobalsat.com/downloads/bt_gpsinfo_android_guide.pdf
Let us know if you have any questions. Thanks.
