BlueChart maps like VPC022R doesn't appear in BaseCamp. You should use HomePort instead as catymag suggested. Seems however that you're on a Mac and then you should try [Only registered and activated users can see links. ]

[Only registered and activated users can see links. ] isn't the perfect choice for a GPSMAP 78. There's a lot of "Vision" data that the GPSMAP 78 can't handle and that storage space is then wasted in the unit or at the memory card. Have you tried [Only registered and activated users can see links. ] ?


The benefits with a BlueChart g2 Vision chart in a GPSMAP 78 would be that it contains higher granularity in depth soundings plus more POIs for land based objects. All BlueChart g2 Vision uses Garmin NT compression and that may slow down map rendering and screen refresh time in a handheld units with slower CPUs.

BlueChart g2 are all non-NT maps and gives faster response times.
