The Mavic 2 supports DJI Goggles (white) version 01.04.0500 (or later versions). It says so on the FAQ section on the mavic 2 product page.
I can not find a firmware version higher than 01.04.0400 via DJI assistant.
Will there be an update soon ?  Or already present, where can I find it ?

I found the latest FW  version .500 using the DJI assistant 2 software connecting to my PC. I already updated it. Please note that you will only be able to use the 2.4G band using the standard goggles. The RE goggles will be able to use both 2.4 and 5.8G bands. RE goggles FW .600

Hi there, we're sorry that the white DJI Goggles does not support the Mavic 2 series for now. Our engineers are working on it and will release as soon as it is ready. Thanks for your patience.

+1 having the same issue and eagerly await the updated firmware.

+1 as well

Uggg spent hours trying to figure it out today

Firmware V01.04.0500 appears to be live via DJI Assistant 2 (1.2.4) - just updated my DJI Goggles.  Seems to work just fine so far - paired it successfully with my Mavic 2 Pro.
