They may just be asking for your serial number, which in the picture is 46000007.
I actually think you are wrong there. System-ID is used with GTN boxes, not GNS. I update GNS boxes, without any problems.
For a registration and Update Jeppesen need my ID.
I never have need a ID for Updates with JDM. Unfortunately, a call is not possible due to Corona.
System ID isn’t used with the GNS equipment. It’s used with GTN and displays to tie the database subscription to the aircraft and not a particular box. System ID is stored in the configuration module of a unit and is located in one of the harness connectors.
That’s nested somewhere in the software menu.
Can someone tell me what the Garmin System ID is?
