Thread: Navionic Hotmap Question

I have a Hotmaps Premium card for the east which I bought new in 2002. How can I determine if Navionics has any new information for the east?

Trying to determine if a new card would be of any benefits.

thanks

Here's a link to the Navionics webapp...It is the latest data...

You can zoom in to your area and compare it to what your card shows on your unit...

You can also post the same question here...
