Waypoint GPX file format for data MFD A78

I have read that the MFD A78 takes waypoints in the DDMMM.MMM format yet it looks like the data in the file is all DD.DDDDDD is that correct?
If I have a file of DD.DDDDD format waypoints do I have to convert them to DDMMM.MMM if I want to import a file of waypoints?
