Vision & Module with atrcs update help

[GNX430]

HI,
I have 2 old Module radios with the atrcs updates and a airplane Vision radio. I don't know how to tell what version I have on the radios and what was the last update. I would like to upgrade the 2 Module radios to the newest updates and was wondering if i could change the airplane Vision radio to the sailplane update at the same time? I was told there was someone who did this in the LA area years ago and was hoping someone on this site knows of them or where I can get this done still. Thanks Jerry

How many planes will the older ones hold, 4 or 8?

That is one way to tell right there.

As I turn them on it looks like all 3 Modules radio with the upgrade say 4c. So i am guessing that is the 4 model, They all say 1998? So not sure when the 8 model version was released? The airplane version Vision radio I have doesn't say how many? Is there a chip inside like a car that can be copied and then switched out or reprogramed like they do in cars? What i am after is the newer version have a slide lever on the right side of the case that comes very usefull in scale ships where we have many moving surfaces on the wing and want to gang ail. and flaps to move together.
Thanks for the help.
Jerry
