raymarine E120

[surazo]

Dear sailors , My E120 working fine and is connected with radar ,DSM and AIS via NMEA but it star to going off -on each time faster and I decide leave on .
The voltage is around 13V .Some suggestion about the problem ? or I need to take off and send to a technical staff .It could be for a recent upgrade made to the plotter and not to the auxiliary equipment?
thanks for your advices

There has been no updates to that system for over 5 years.

The system is very old. Start saving to replace all of it.
