I have two screen setup. An AF-4500 configured as an EFIS combined with an AF-3400 configured as an EMS. When updating the software for each do I load the latest 4000 series software - (AF4000 V8.08.25-MV16 System Software Updated 4/4/14) into each device or will the software update uploaded to the AF-4500 EFIS be transferred automatically to the AF-3400 EMS?

Also, is the AF4000 V8.08.25-MV16 System Software Updated 4/4/14 used in the AF-3400 EMS?
