You need to have the latest Firmware installed on the
goggles.
To update the
Goggles firmware, download the version of DJI Assistant from the
Goggles Downloads area of the DJI website,
(not just any DJI download area, the
Goggles Downloads area).
Unfortunately, my sense is that not all versions of DJI Assistant are the same and there is not an obvious indication of this.
Some Assistant versions are for the Mavic aircraft, some for RE
Goggles and some for regular
Goggles.
Connect the
goggles (only) to your computer and update the
goggles firmware with DJI Assistant.
After updating, have the RC controller and Mavic Zoom powered up and connected. Power up the
Goggles.
Follow the DJI website for general instructions on connecting to your Mavic.
An important item is in the
Goggles Settings under the Link menu, where you select "
Mavic 2" as the type device to connect to.
Good Luck!
