Got my GP1971F done and then got a C-map 4d for our area. Read the manual and did not install with power on, just added that so it isn't asked. Everytime I install it, put it in the slot, either upper or power port, I get a No Chart Found flashing. I've tried each port to no avail and put it in my laptop and items showed up in the file. Do I need to list the disc in the 1971or hit Import ? Or did I get a bad disc?
