2GIG GC3 Wireless Security SystemThe new 4G LTE cellular communicator needed for Alarm.com service requires a firmware version of at least 3.1.3 or higher to recognize the cell module.  You can update the GC3 firmware yourself without incurring an Over-The-Air (OTA) cellular charge from Alarm.com.

NOTE: If your current firmware is below 3.0.2 be sure to update to 3.0.2 first then update direct to the latest firmware.
