I have copied the built-in-chart from my 7616 onto a SD card. When I try to load in Homeport, only Hawaii area will show up on the Blue Chart v2016.5. The Lake View chart loads fine. I first used a 8G SD card and thought maybe it was to small. Tried a 16G card and same problem. There are no errors when copying from my unit to the sd card. Do not understand why Homeport will not load the map of the United States. It will bring in my waypoints. Any suggestions on what is going on? Thanks ciq.forums.garmin.com/.../1231714.jpg
