1. On your NT, download TetherGPS Lite from here:
2. Install TetherGPS. When prompted, enable 3rd party apps and enable mock locations in the development settings menu.
If the Application Settings menu doesn't pop up, you can get back to it by downloading something I hacked together to get to the menu (tgps_launcher) from the address above. Click start in tgps_launcher and the menu will open.
3. Install Google Maps. I have an older version of the APK at the site above, or you can find a newer/better one.
4. Make sure the NT is connected to your phone's wifi hot spot, the TetherGPS server is running on your phone, and the TetherGPS client is running on your NT.
To launch any of the apps, you can click your "n" button, hit search, and start to type in their names. They will appear in, and can be launched from, the search list. (thanks to jdlothar for this tip!)
