Since January 1, 2026, some operators are noticing missing activations or ‘Invalid Activation Code’ errors on certain GreenStar™ displays. This issue has been documented through John Deere DTAC cases and is tied to how date and time are recognized within the system.

Displays Potentially Affected

• GS2 2600
• GS2 2100
• GS2 1800
• GS3 2630
• GS3 CommandCenter

What’s Causing This?

The issue is related to how these displays handle date transitions beyond 2025, which can impact activation recognition.

Solutions by Display Type

• GS3 2630 & GS2 1800
• Update display software through StellarSupport
• This update can be completed by customers if preferred
• GS3 CommandCenter
• Install the latest software for the VTV or VTI controller
• This update requires a technician due to EDL use
• A PIP program is expected to support this update
• GS2 2600 & GS2 2100 (Workaround)
• There is currently no software update available, but functionality can be restored with the following steps:
• Navigate to: Menu → Display → Settings → Time/Date
• Uncheck: “Use GPS Time and Date” (or “GPS Time Sync”)
• Set the year to 2025 or earlier
• Perform a cold boot:
• Power off
• Disconnect power for ~30 seconds
• Reconnect and restart
• Important:
• You may still see an “Invalid Activation Code” message
• Display functionality will still operate normally
• Work documentation remains accurate, as it continues using GPS time
