				Any of you out there using the MX-20 connected to either a 400W or 500W series GPS?
 
 I have a 420W connected to a MX-20.  Recently upgraded the software in the 420W and now the MX-20 screen map area is blank with the red X in the middle unless I have a flight plan active.  I have verified my wiring and settings - along with the system showing my position with the flight plan active so i am confident in the wiring / settings.
 
 The 420W is running 5.3/5.0 software and the MX-20 has been tested up to version 5.7.  My understanding is that a newer version of software is available for the MX-20 and I am making inquiries as to upgrading.  My question to other users is - Does it work with the later software - or did Garmin abandon this device already!?
 
 Thanks,
 Ralph Capen
