Drifter2

Hello,

Issues I am encountering:

MFD is over heating. To touch the unit it feels extremely hot at times almost too hot to keep my hand on it. I intend to add some fans to cool the unit from behind.
Is this normal to require additional cooling?

Random system power cycle on its own. I suspect from the over heating?? It is as though I just turned it off and on again.

I am loosing random squares of sonar chart recordings of about 1/2 mile. Recently I had a square of sonar live info that would flash on then off repeatedly.

Today I started the MFD and my entire system had reset to default settings. I have lost All waypoints and all information saved on the MFD. Sonar chart data that I have recorded was not lost.
Is there any way of recovering my lost waypoints?

The unit was used on another boat without issue and only since the recent install on a different boat have I run into these issues.

A general opinion on the situation with any pointers on how to sort it out would be helpful.
