The Federal Aviation Administration (FAA) recently decommissioned two WAAS GPS satellites (PRN 122 and PRN 134), and the activated two replacement satellites (PRN 135 and PRN 138). The WAAS firmware in certain Raymarine products does not recognize satellites 135 or 138. All of the Raymarine products affected continue to receive the standard GPS signals and therefore are safe for navigation.

We are pleased to release a software update for Raymarine C-Series (C70, C80, C120) and E-Series (E80, E120) Multifunction Displays that restores the ability for their connected Raystar GPS sensors to detect, track and utilize the new WAAS PRN 135 and 138 satellites.

Step 1: Requirements for Upgrade
Raymarine C & E-Series displays are field upgradeable using a common CompactFlash (CF) memory card. For performing upgrades on Raymarine CF compatible products we strongly recommend using a SanDisk brand "Shoot & Store" or SanDisk brand standard grade CompactFlash card. Raymarine can not guarantee other CompactFlash suppliers will offer the correct specification card for a successful software upgrade.

Step 2: Software Upgrade Procedure

1. Back up your existing waypoints, routes and tracks. Failure to create a back-up could result in the loss of this data from your multifunction display. For step-by-step instruction on how to perform a backup please consult your MFD Operating Guide, or read FAQ 1145: Backing Up Waypoints, Routes and Tracks on C & E-Series.
   
   
2. Please review the instruction for upgrading your Raymarine Multifunction Display software. Complete step-by-step instructions are available online in FAQ 1219: Upgrading the software in C70, C80, C120, E80 and E120 Displays
   
   
3. At the conclusion of the upgrade you will need to confirm that WAAS reception is enabled in the display's GPS Status menu. To do this:
   1. Permit the display to boot up.
   2. Press the OK button to acknowledge the Navigational Warning
   3. press the MENU button to display the Setup Menu dialog
   4. Use the Twist-n-Click knob to highlight GPS STATUS within the Setup Menu dialog and then press the right arrow on the trackpad.
   5. Press the OTHER SETUP soft key.
   6. Use the Twist-n-Click knob to highlight WAAS within the GPS Setup Menu dialog, press the right arrow on the trackpad, use the trackpad to highlight ON, and then press the OK button.
