Thread: How to install custom maps in Garmin GPSmap 620 and 2010C

Is there a way to modified the 620 to display Symbol and Comment?
Now to the 2010C chartplotter. I think I did not make my last post very clear. The 2010C does not read image files, only the older format Bluechart data card. I can transfer/merge the waypoints from a .gdb file using the Data Card Programmer but the map blue water colour does now show as it appears in Homeport/Mapsource. The shore outline would appear to be ok. Perhaps if this is still confusing, I could send the two different screen shots of the maps. Also, I would need to display Symbol and Comment similar to the 620. I'm sure you will succeed with this challenge.

Goimen, I've added pictures to best describe what I'm saying with regards to the map display.
I've shown how the same part of the map differers on the 2010C and Homeport. On the 2010C, 'The Moorings and Marine' are embedded in the custom map. In Homeport you can see my comments (notes) which show the waypoint names that I wish to display. Just for clarification, last picture shows the display options I refer to in Homeport.
Hope this helps.
