We have a handheld garmin 78sc gps and we are having the charter company install a raymarine es75 chartplotter on the boat. Can I get a chip with the caribbean charts on it that will work in both of them?
As a factory authorized Garmin dealer/reseller/installer I try pretty hard to be as accurate as I can be, and my post was indeed accurate.I am the last one to question your authority, Maine, but I don't think the card for Garmin 78sc would work in any Garmin chart-plotter (741, or 7607).
If I recall correctly, GPSMAP 78 uses MicroSD cards and a different format maps than the 741 and similar (and they use the SD card).
However, no question, there is no map compatibility between Garmin and Raymarine systems.
Garmin keeps their charts proprietary so I don't think there is a chip that will work with the handheld Garmin and the Raymarine. Navionics has a SonarChart for Garmin chip that works on the older plotter units (a software update on newer units prevents Navionics maps from working), but I don't think it would be compatible with the handheld. If you're set on the Raymarine unit and you get one with wifi, you can plotter sync to a tablet up on deck instead of the handheld Garmin...just a thought!maybe navionics can answer that question
