My new-to-me plane has a G430W and an MX20 MFD. It is my understanding from flying it for a while that the MX20 is kinda a slave to the 430. Is that a correct interpretation? I enter my GPS course on the 430 and I see it on both the 430 and the MX20.

Reason I ask, is I am updating the 430 database after getting the plane back from Mx and noticed there is a database upgrade for the MX20 too.

Enlighten me...
 
i have the later version of MX20 called MX200, it is configured as slave to my 480 and its a joy to buy database upgrade AND navaid database/ terrain etc upgrade for the GMX200. I suspect yours is the same case. I also have the Jepp chartView unlocked, but I aint paying for the approach plates
 
By default an MX20 and GMX200 has no position source of its own. It's essentially just a Windows NT box that displays maps. It has the advantage that it interfaces to a number of various devices including most of Garmin's IFR GPSs and a variety of weather and traffic units.

I have an MX20 but its soon to go byebye. It's getting long in the tooth. It's a little low on memory these days and will occasionally crash if the NEXRAD gets too complex.

Right, that's what I meant. It takes the GPS signal from the 430, but the MX20 has its own underlying map that needs updating.
 
I only update my mx20 database like every 36 months or so. Not really an issue as airports and mountains don't move terribly often.
 
I only updated it more often because I had the ChartView feature.
