Some confusion on compatibility. I have a GPSMAP 1042xvs, the overview page shows GPSMAP 10X2 as compatible but detail page on U.S. & Coastal Canada - Lakes, Rivers shows only GPSMAP 1022 and 1022xvs as compatible.
Time to call Garmin.
Are you sure its a subscription? You can purchase the Micro SD card just like the old charts or do the download. Maybe if you want daily updates thats a subscription?
And the compatibility is a question. I have 2 older 741XS but jus bought a new 923XSV. It shows the new unit as compatible but the older ones not compatible. I did buy the GMS 10 Network port expander. I wonder if I use the charts on the 923XSV if I can display them on the 741XS
