Is there a way of enabling the grid lines within the googles view when they are connected to the Mavic Pro? I was unable to spot any options within the Googles menus.

I don't believe there is.

Hi, thank you for bringing this query for us. We can only enable the grid lines on the DJI Go 4 application and we don't have the option to enable it on DJI Goggles. Hope this helps. Thank you for your understanding. Cheers!
