We usually do not suggest flash firmware or MCU.
Because radio product have many restrictions, and it will break the warranty.
For firmware:https://mega.nz/#!HCQ2GQzQ!wrQs_iI_P9ZILw9lBzPVzFyn_SHiJqdx0TQTcqjstZg
Method:Put the nupdate.img file in the root directory of the sd card, insert the GPS card slot, click Settings - Expand Settings - System Upgrade
For MUC update:https://mega.nz/#!rLJHDCQC!LFk4BunIbi3qwRyS7ncGO8QROAI8cdJAzTEIcvUks2Y
Method: Do not decompress the file in the sd card root directory, insert the GPS card slot, click Settings - expand settings - mcu upgrade.
Hope you can fix the radio.
