TBS Oblivion GPS Addition - Change of Firmware Needed
Please see the video link at the bottom of this page for additional help
Using the BN-180 GPS Module and the TBS Oblivion stack, you will want to do the following:
1. Leave the wire colors from the BN-180 plug untouched (see below):

Then make sure to change the wiring for the other end of the plug to match the TBS input (see below)

You will then need to downgrade your firmware to BF 3.1.7 (click here to download)
Once you have done this and flashed the FC, make sure to do the following:
1) In the ports tab select GPS under UART3 Sensor Input (57600) - Then save
2) Go to the Configuration Tab and make sure to change the protocol to UBLOX and ground assistance to North America. After that you will be working.
