You will need both the card, and the unlock code. The unlock code ties to a
unit code within the GPS itself. Bluecharts can be used with up to 2 units.

Can somebody tell me if I can download (assuming I have a serial cord etc)
BlueChart Americas from my computer directly to the unit without having a
data card. And will it be functional on my GPS...it is on my
computer.......Will I need an unlock code also?
Thanks
