Currently have a Navionics+Updates card and I am familiar with its use.
Thinking about a second Updates card and have a card to use for that registration.
What is the difference(besides price) between theNavionic+ Updates cards and a Navionics+ large cards?
Do they function the same as far downloading nav and sonar maps?
I don't need the 3d, satellite or panoramic views the other area cards offer.
I admit I did not read all 83 pages, but did a search which did not help.
Thanks
