Ok now I'm really confused. If the MapSource version includes the 3D/Lane Assist/JCV, how do I transfer this to my device? Is this data somehow integrated in the GMAPSUPP.IMG file? When I browse my Garmin device there is a JCV folder which contains the older junction view file (.jcv file). Do I need to upload this as well as the gmap3d.img file to the /GARMIN/ folder on my Nuvi 1390T? Please excuse my ignorance! I have experience working with the .IMG files but the 3d view and junction view is new to me.
