Why Update Your C-Map Chart?

It is very important that the latest C-Map charts are used when sailing out in the open water for safe navigation purposes. The C-Map electronic chart libraries get updated twice a year to coincide with popular boating sessions. Included in the library updates are the latest notice to mariner updates from government hydrographic offices, updates to marina facilities, port services, photos and more. Navigational updates to C-Map charts include: 

  • Buoy, beacons and lights.
  • Shoreline areas and shallow water depths.
  • Channels, commercial shipping lanes, and restricted or dangerous areas.

Why Exchange Your C-Map Chart?

It is recommended to exchange your C-Map chart on your cartridge if you no longer sail or visit the area on the chart to more suitable chart coverage. The exchange process will allow you to receive a brand new chart at the reduced update price. Mail us your C-Map cartridge and we'll exchange the chart on the cartridge to the chart you order.   


How the C-Map Chart Updates & Exchange Process Works 

Simply purchase the update version of this chart or the update version of the new chart you want to exchange for by browsing through our C-Map update Max-N chart collection (exchange offer only valid if the new chart is the same price class as the current chart on your cartridge). Once your purchase has been made we'll email you a link to our customer return portal where you can enter your order # and email address to login to generate a return label. Once we have received your C-Map cartridge we'll program it accordingly with the update/exchange chart ordered and send it back to you. Please note there will be two shipping charges involved in this process, one to ship the cartridge to us and another to send it back to you.
