The CP450C can be upgraded via any of the following Multifunction Displays (MFD) via appropriate RayNet-to-SThs or RayNet-to-RayNet adaptor cables for C-Wide / E-Wide / E-Classic / aSeries / cSeries / eSeries.  You will also need:


  • a commonly available microSD memory card,
  • a memory card reader for your PC or Apple Mac computer,
  • a microSD to SD memory card adapter or a microSD to CompactFlash memory card adapter,
  • and the latest Raymarine CP450 software.


Note: Although you can upgrade a CP450C from an E-Classic, E-Wide or C-Wide, you cannot test the CP450C with these MFDs. The CP450C will only work with the new aSeries, cSeries or eSeries MFDs.

Note: microSD memory cards used with a/c/e Series MFDs should have a memory capacity of no less than 256MB and no more than 32GB. To avoid potentially corrupting the data on your Navionics chart card, DO NOT copy software update files to your Navionics chart card and DO NOT back up waypoint/route/track data to your Navionics chart card. MicroSD cards are commonly available in most stores selling consumer electronics products. Waypoint, route, track data, and system configuration data can be stored on a microSD memory card which also contains software update files.


Populating a microSD/Compact Flash Memory Card with CP450 Software

  1. Insert a compatible memory card for the display you are to use into the computer's memory card reader or into a memory card reader which has been interfaced to the computer.
  2. Select the appropriate software download for your product from HERE
  3. Upon completion of the download, click on the downloaded file to open it
  4. Copy all files to the Root of the card (Root is the first level you access when selecting the card).  Make sure the files are not in any folders on the card

    For example, if your computer has assigned Removable Disk (E:) to your memory card reader/writer, then the software update files (i.e. the DOB and PKG files alone) should be copied directly to Removable Disk (E:), not to any folders created on the memory card.

  5. Remove the memory card from the computer's memory card reader.


eSeries / cSeries / aSeries

1. Insert it into the MFD. Keep the MFD powered off at this stage.

2. Power up the CP450C and observe a flashing Amber LED on the CP450C (no network).

3. Power on the a/c or eSeries and let the unit run the “Remote Upgrade” script. It should automatically acquire the CP450C on RayNet and program the unit.

4. Whilst programing the CP450C the LED will turn RED. Once programmed the LED will turn to SOLID Amber.

5. Once the MFD states “Upgrade Complete” and there is a SOLID amber LED on the CP450C, you can then power cycle the CP450C.

6. Remove the μSD card from the MFD and let the MFD reboot. Enter the diagnostics menu to check the CP450C revision states v2.04.

7. It’s recommended you perform a reset on the CP450C and the depth offset calibration is checked.

8. Test the CP450C to ensure it is operating as expected. The CP450C is now upgraded to v2.04 software. 

C-Wide / E-Wide / E-Classic

1. Insert it into the MFD. Keep the MFD powered off at this stage.

2. Power up the CP450C and the MFD and observe a flashing Amber LED on the CP450C (no network).

3. Select v2.04 from the upgrade screen on the MFD.

4. Wait for the upgrade to show complete on the MFD (Disappearance of the progress box) and check the RED LED has changed to a SOLID Amber LED on the CP450C.

5. Then perform a power cycle on the CP450C. Do not power cycle until you have a Solid Amber LED, indicating an upgrade has been completed.

6. Now check the software version of the CP450C in the MFD diagnostics screen. Note - the MFD may report the CP450C as a “DSM350”(see screenshot).
