C120 intermittenly shuts down during operation. Raymarine advised to update to 4.29, perform factory re-boot after saving waypoints etc to CF chip. ALL of these were done, same results...auto shutdown or reboot.
Had installed Sirius Satellite Weather. Raymarine advised Sirius had an issue that was being worked on, and to disconnect the SR50 receiver. Sirius had no knowledge of a problem. When the Sirius was disconnected, the C120 started fine and within two minutes shut down automatically.
A friend reported several others had reported the same problem.
I smell a rat and need a solution. Any help would be appreciated.
Before you turn on your C 80 or C120
press the first grey keypad near to the powerbottom and than the powerbutton together until you get factory reset.
So you will solve the problem.
Software 4.29 is OK

Re: C120 Chartplotter Auto-PowerOFF
Either it's not getting enough power on the bus or there may be a problem with the unit or something hooked to it. Remove everything but power and leave the unit on. If it powers off by itself then check your voltage, if voltage ok and the leads are not corroded, send it in. If it does not power off hook things up one by one. Leave it on each time. I've seen GPS's not provided with additional power on the seatalk do this. Even though the E-series outputs power on seatalk they made a revision in this concept and now what you to power the gps externally. That may be the only problem you're having or your seatlk bus is internally breaking down.

It sounds like the fault is within the plotter itself. There should be any component, which shorts with main power supply, causes the blow of fuse to overload. I do advice you not to try to repair it by yourself, and contact the authorized service center. Gopakumar Gopalan Google
Sophistacated testing instruments are needed to repair this type of devices.
It would appear you need to perform a hardware reset.
6.2 Resetting the System
Three types of reset are available for the Chartplotter:
• Power-On Reset: When you turn the display unit off, then on again,
the screen reverts to the chart display with all windows cleared.
• Hardware Reset: This procedure enacts a power-on reset if the unit
has entered a lock-up condition.
To perform a hardware reset, press and hold the POWER key for 9
Probably a bad printed circuit board, just had to send mine in to have it repaired. When I hit the power button, I did hear a beep, but then nothing displayed. Mine was still under warrenty, so don't know the repair cost if yours is not.
My A65 was constantly shutting itself off. I did the reset and the unit is working just like it should now and I have had no more problems.
Go to Setup, System Setup, then Settings Reset and press Enter. This returns all settings back to their original factory values. It should not reset your waypoints or route lists. Raymarinerecommends you backup your waypoints on a separate Compact-Flash card but I didn't do that as I wrote down my all my coordinates. Hey I'm a fisherman all I care about are my fishing spots.
I'm not sure what setting it was that I changed that caused the adverse affect of the unit shutting itself off but resetting the unit did the trick. I was more careful about adjusting the display settings to my liking by doing them one at a time and waiting to see if the problem returned. It has not so far, knock on wood, and the unit is working the flawlessly now.
With the charts page up, start by hitting the find ship softkey at the bottom of the screen.If that find the boat on the chart all is good.If not you need to check you have a GPS fix. Go to GPS screen and see you are seeing satalites.
If all is good when you hit find ship and the boat disappears again from chart while underway you will need to go into the chart setup menu and see if the screen amplifier is turned off. If off turn on.This is first place to start. Hope that helps
Was the engine running when it shut off? How was the voltage at the time it failed? The A65 will shut down if the voltage drops below 11.2 volts.
Another common cause would be corrosion on the plug where it plugs into the back of the display, or the terminal connectors that attach it to the boat's power supply.
It could also be a bad crimp on the terminal connectors. Make sure connectors are the right size for the wire and that they are marine grade, such as Ancor brand connectors. I also recommend heat shrink style connectors,
I have not heard of any software issues for that model so I am betting it's a wiring issue. However, there is an update available from Raymarine. There were changes made to the WAAS satellites and the update helps it recognize the new satellites. You can download it for free from Raymarine. Copy it onto a blank CF card and plug it into the card slot on your GPS. When you turn the unit on it will prompt you on how to proceed with the update. It will fix any known software gliches at the same time.
I hope this answer helps. Please reply if you have any questions about my response.
