MGL Avionics User Forum

Hello,my name is Eduard, I am a newcomer to aviation, but I have a lot of experience working with cars. I am installing avionics in my self-built aircraft. By default, the settings were configured for a Rotax engine, but I was unable to change the settings to UL Power manually. I decided to update the firmware, but when I pressed the "Firmware Upgrade" button, the EMS Extreme G2 simply shut down.

Has anyone encountered a similar issue?
Thanks in advance for your help!
