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
into my chartplotter
from my phone
, is there any reason to pay for an updated card too?
