Raymarine C120 rebooting problems

[captainhaddock]

My C120 chartplotter has worked fine for about two years, but this weekend it started auto rebooting on a frequent basis - running for between 15 seconds and about 10 minutes. I refitted the cables several times, but this made no improvement. Can anyone advise me what to do next?

Assuming that the softtware is the same as the C80, there is a software upgrade that is supposed to cure this.

Thanks - I will check for updates - although it seems strange that it should suddenly have become a problem when previously it worked fine.
