#Unable to get Betaflight OSD with O3

I'm building my first quad using DJI O3. I'm getting video feed but no Betaflight OSD. I couldn't figure out the issue no matter how much I searched, I'd appreciate any help.

I connected the unit to the FC using the 6 pin cable that came with the unit. I'm using SpeedyBee F7 V3 FC. If I'm understanding it correctly I need to use UART1.

I applied the preset named "OSD for Fpv.wtf, DJI O3, Avatar HD" using the "uart 1" setting, which applies these commands:

set osd_displayport_device = MSP set vcd_video_system = HD serial 0 131073 115200 57600 0 115200

I set the Canvas Mode in my DJI Goggles 3 to "HD".

Video Settings in OSD tab is set to "HD".

"OSD" option is enabled in Configuration tab.

Air Unit and Goggles 3 have the latest firmare. FC has Betaflight 4.5.1.

Any idea what I'm doing wrong or missing? I'd appreciate any input.

@split prawn Can you check that the pinout of the plug matches with the O3?

@wanton hound It looks correct to me but I'm not an expert so I'm not sure (I flipped the FC socket image to simulate underside display)

@split prawn Just checking if you know, in UART most of the time RX of one device goes to TX of the other and vise versa

@split prawn I suspect it's the OSD mode you have enabled

if AUX 3 isn't covered by the range, the OSD will not be displayed no matter what
