So I guess my question is for those who have the GDL 39R installed, will the "3D" function work as is with the ver. 6.0 Garmin Pilot app, or is this a firmware update or software update to the 39R? The Garmin site lists the GDL 39, 39R, and 39 3D as all one part number, which would imply that they are all one in the same? I'm confused.
