I just update my airunit & goggles with the latest firmware (v01.00.02.00), but the osd seems not working at all (battery voltage also missing), i used all recommended parts from dji website. I also change custom osd at goggle to "On". any help would be greatly appreciated.

FC & ESC : Tmotor F55AproⅡ +F4 HD STACK
Betaflight : 4.1

I have the same FC, ESC and Betaflight 4.1 and it works perfect. I see you have activated in the osd tab some values ​​that do not work yet. But the main problem is that your voltmeter also shows nothing. Did that go before the update? If not, your RX / TX is reversed. You also did not select GPS as Sensor in the UART tap.

You need to activate MSP for the UART thats connected to the DJI FPV System

For sure this ^

You can see in your ports configuration that you only have the 1 MSP, you should have a 2nd MSP for the DJI FPV system or you won't get any of the integration, even before this recent OSD update.

As prevouis people has sad. Active MSP on UART1 most likley.
