Here are the instructions from
Raymarine:
Upgrading the C-Series or E-Series MFD
Now that you have backed up your data for safe keeping, we will upgrade the MFD
software.
Turn off the power to your MFD unit, and remove any installed
Navionics Chart or CF memory cards.
Insert the CF memory card containing you just prepared into the card slot on your C-Series or E-Series MFD.
Turn on the MFD unit's power with the red power button.
The MFD will power up to a
Software Update Utility
screen like that pictured below.
In the column on the left under "Upgrade Packages Available" there should be a
single file listed. Its name corresponds
to the name of the PKG file that you copied to your CF memory card.
Note:In the event this CF memory card has been used for previous upgrades of the MFD, you may see previous upgrade
packages available as well. Highlight the one corresponding to the latest software version using the track pad control.
Press the soft key labeled "UPGRADE THIS UNIT."
You will see first a
single bar, then a double-bar progress indicator appear indicating that the software is being transferred.
This process can take up to 90 seconds.
When the progress indicator reaches 100%, it will disappear to indicate that the software upgrade is complete.
Remove the upgrade card from the card reader slot.
Press the soft key labeled "REBOOT."
The MFD will restart and come up in normal operating mode.
You can confirm that the upgrade was successful by examining the "Navigation Warning" dialog box that appears at startup.
The software version installed in the MFD is indicated on the lower right corner of the box, as illustrated below and circled in magenta.
Press the OK to continue as you normally would.
As a final step in the process we must reset the MFD for the final initialization of the new software to occur.
Press and hold down the power key until the MFD shuts off.
Press and hold down the left-most soft key, while simultaneously pressing the releasing the power key.
The MFD will power on, then the words "Factory Reset" and a countdown 3...2...1 appear.
You must hold in the left-most soft key throughout the entire countdown.
The MFD will then restart. When the "Limitations of Use" disclaimer appears, press OK to accept the terms.
Power off the MFD.
Press and hold down the left-most soft key, while simultaneously pressing the releasing the power key to perform a second Factory Reset.
The MFD will power on, then the words "Factory Reset" and a countdown 3...2...1 appear.
You must hold in the left-most soft key throughout the entire countdown.
The MFD will then restart. When the "Limitations of Use" disclaimer appears, press OK to accept the terms.
You may reinsert your
Navionics Chart card at any time.
At this point the MFD is ready for normal operation. You should restore your waypoints and routes from your CF memory card.
As well, if you customized any of the settings (ex. page customization, units configuration, chart layer configuration, etc.),
you will need to manually re-configure these settings. Please refer to your owner’s handbook for more details.
