I am about to upgrade my coastal marsh duck boat by adding a garmin 400 series chart plotter. I already have a gpsmaps 78 that I want to continue to use as my backup.
Garmin is currently running the g2 vision rebate of $200 which makes the software only $40
Now the question:
Can I use home port to download identical data to both devices? Or is the g2 software limited to one device.
Thanks
