The GP1971F is NOT a network product. While it can share sensor data and other information to a TZT or TZTl it is only through being on the same N2K backbone.
Waypoints will not transfer via N2K. Both the GP1971 and the TZTL use GPX or CSV format so you should be able to transfer waypoints via a micro SD and a USB. See the files section of the product manuals.
