Adding additional monitors to vx2 7 inch unit ??

[KingFisher99]

I just bought a boat that has a sun beaten 7 inch unit VX2. I am looking to ad some additional monitors down below in the cabin. Is this the unit (pictured ) that can accomplish that? Any advice is appreciated as this is an older unit. I might also buy a used 10” vx2

Vx2 black box processor provides VGA (640x480) video output to a monitor. It would work on the network with the 7" Vx2. Only one of those keyboards is used.
