On our last passage from Acapulco to Zihuatanejo
Our chart plotter was showing some of the screen not colored in. There was white space on the screen.
Garmin support has since suggested we upgrade our software which we are about to do. We have an older 3.6 version on our plotter. Hoping this will fix the problems?
A trip to shore and lunch at a favorite Loncheria that serves up home cooking and also has good WiFi was in order. Debbie brought her Kindle Fire and downloaded the software there. Once back at the boat Debbie copied the software to the PC and from there she installed it onto the SD card like Garmin wants. Next Debbie installed the SD card into the Garmin 740 chart plotter and upgraded the software and it worked on all units on the NEMA 2000 network.
