I have purchased on DJI site Mavic 3 Pro combo with Googles2 and. RC Motion 2. Now I found it impossible to conect googles to Mavic 3 Pro since Google 2 gives me the option only for Avata or some other stuf. How to do it?

please follow the instructions found in this video:

Hi, fans29858792. Thank you for reaching out. When using for the first time, make sure that the aircraft/Goggles/DJI RC motion 2/DJI Fly app are all updated to the latest version:
Mavic 3 Pro - V01.01.0100 and above version
DJI Goggles 2 - V01.06.0000 and above version
DJI RC Motion 2 - V01.01.00.00 and above version
DJI Fly APP - V1.10.0 and above version

Please check whether the linking operation is correct. Operation steps:
1. Power on the aircraft, the goggles, and DJI RC Motion 2 separately. Press the Power Button once, and then press and hold the button for two seconds to power on or off the device.
2. Press the Link Button of the goggles, and the goggles send out short beeps.
3. Press and hold the Power Button of the aircraft until the Battery Level LEDs blink in a cycle.
4. After linking is successful, the Battery Level LEDs of the aircraft are solid on, the goggles stop beeping, and the image transmission screen is displayed.
5. Press and hold the Power Button of the aircraft until the Battery Level LEDs blink in a cycle.
6. Press and hold the Power Button of DJI RC Motion 2 until it beeps and the Battery Level LEDs blink in a cycle.
7. After linking is successful, the Battery Level LEDs of both aircraft and DJI RC Motion 2 are solid, indicating the battery level, and DJI RC Motion 2 stops beeping.

There are two important points that need to pay attention to during the linking operation:
1) When linking different aircraft, you need to switch to the corresponding aircraft model in the goggles first: (The highlighted drone is Mini 3 Pro for example. Please choose your corresponding drone model)

2) The order of the linking process must be to link the aircraft with the goggles first and then link the aircraft with the DJI RC Motion 2.

Hope this helps. Please keep us posted.
