a/c/e/eS/gS Series MFD randomly reboots

Confirm what screen the a125 reboots to. Does it restart at the same point of use, for example straight back into the chart or radar app which you were previously using, or does it reboot to the initial Raymarine Splashscreen (the original start up screen that appears when the unit is first powered on) ?

If rebooting to the Raymarine Splashscreen, then the likely cause is power supply related, it could be a loose power cable connection, a damaged or trapped cable, a faulty fuse holder or isolating switch, or even low battery voltage, another possible cause could be Electrical interference, click here for more information.

If rebooting to the page that you were just using, then the cause could be software related or a faulty unit. You could try to reload the latest software, available from the Raymarine Website and then carry out a full factory reset,, click here for instructions .

If the fault persists, temporarily remove the chart card to see if this stops the rebooting, possibly the chart card is faulty, also turn off the SONAR LOG in MENU/ PRESENTATION/ DEPTHS AND CONTOURS.

If none of the above is successful, Then the MFD should be sent to Raymarine’s Product Repair Center
