The only thing the VHF could put out for any MFD would be DSC call data. Unless it has an internal AIS receiver, then that is very useful.
On the other hand, it is always a good idea to ensure that your VHF is getting position data to maximize your DSC effectiveness.
There was an event recently that resulted in drowning. The operator pushed the DSC button but GPS was not connected. Help did not arrive in time because they were looking in the wrong area.
