HI Tump, I was just informed by OB that its $90 for a mate 1 firmware update.
If its a older version with the AGS bug, then they will upgrade for free. 4.1.2 I believe. jay peltz power On Nov 19, 2014, at 9:30 AM, Tump wrote: > To add; I am a firm believer that every few years I will send OB CC/Mates in > for firmware up date.
