Hi- I have a subscription to (NZ)
charts on my cellphone
Navionics Boating app through 2022. On logging into Navionics/Garmin, it says my
GPS Card subscription is expired. I assume this is the one in my boat's
B&G chartplotter. Since I can sync
charts over
wifi into my
chartplotter from my
phone, is there any reason to pay for an updated card too?
