Just received CAS-15340687-Q8J9G7 back from DJI, can not load map. P4 Pro Plus

Hi there. Thank you for reaching out and we're sorry for the trouble. Please update your remote controller to the latest firmware version manually using the download link below. Refer to the details below on how to update the RC:

1.  Import the file “update.zip” into the microSD card.

Note: If the upgrade fails via SD card, please copy the update.zip file to the internal memory of the remote controller and try to upgrade again.
2.  Power off the remote controller and insert the microSD card.
3.  Power on the remote controller and tap “Install”.

Thanks worked GREAT, can this be used on GL300F also.  (no display)
