  • Please note, it is not possible at this time to update your chart via Mobile or Tablet
  • Visit www.gofreeshop.com
  • Log in, by clicking the “Sign In / Sign Up” Button, on the top right of your screen
  • If you haven’t already, you will need to download Maps Manager, a small piece of software which will allow you to update your charts*
  • Insert your SD Card into an SD Card Reader attached to your PC – ensure that the card is not write-protected
  • Click the “Update” button
  • Click on the “Shopping Cart” icon, on the top right of your screen
  • Click the “Pay Online” button – there will only be a charge if you are outside of your 12-month free updates period, after this you will only pay 50% of the normal retail price to update or upgrade
  • Click “Your Products”
  • Click “Update Maps” for C-MAP-labelled SD Cards
  • You will then have two options:
    • 1. UPDATE VECTOR – this will only update full-feature vector data and high-res bathymetry.
    • 2. UPDATE ALL – this will update the above, plus any premium features such as Raster Chart Layer, Satellite Imagery, Shaded Relief, etc. If you do not select this option, you can always update these layers later.
  • The system will check the cards and start installing update maps to it
  • At the end of the process – which may take a few hours, depending on how much data requires updating and the size of the chart – the system will inform you that the updated card is ready to be used.

Update your X-Generation Chart – DISCOVER™ X & REVEAL™ X

Simrad® NSX®, NSX ULTRAWIDE & B&G® Zeus® S

X-Generation charts are compatible with Simrad NSX, NSX ULTRAWIDE and B&G ZEUS S – for more on compatibility, visit our Device Search.

X-Charts can be purchased from C-MAP.com or through the X-Chart Manager App on your NSX, NSX ULTRAWIDE or Zeus S, operating latest software (NEON 1.5 or later).

To update your chart, you will first need to download X ChartManager

 

 

Minimum Requirements: You will need a microSD / SD Card Reader and internet connection
Windows – Windows 10 or higher, with latest updates installed
Mac – OS X 12.5.1 or higher with latest updates installed

  1. Launch the X-Chart Manager on your computer and log in – you will be prompted to set up a new account if you don’t already have one
  2. X-Chart Manager will prompt you to insert your SD Card
  3. Your card must be Registered – you will be prompted to do so if it is not already Registered
  4. You will now be able to see the boundary of your chart

Pro Tip: For quicker, easier, downloads you no longer need to update the entire chart area – simply select the areas you use for the best experience. You are still able to update the entire coverage, but this will take longer.

  1. To update, click on “Add A New Area” and draw around the area you want to update
  2. X-Chart Manager will run a data check. If updates are available, click on the “UPDATE AREAS” button presented

Pro Tip: The Satellite and REVEAL Shaded Relief layers in the REVEAL X contain rich data, so take the longest to download. If you don’t need these layers, or need a quick update, you can choose not to update these layers.

  1. Select the layer(s) you want to update and click “UPDATE” button
  2. IMPORTANT: DO NOT REMOVE THE SD CARD WHILE THE UPDATE IS RUNNING
  3. Your computer will tell you when the update is completed. After ejecting the SD Card via Windows or Mac OS, you may remove safely it from your computer
