I have the above unit fitted on my small boat.<br />Going into a head sea the unit keeps shutting its self off, and is happening more frequently.<br />Once it turns itself I just press the button and it starts up again no problem.<br />I've checked the wiring and electrical connections, which are sound.<br />My thinking is that it could be a "dry" connection in the unit, it's probably going to be exspensive as the unit is six months out of warranty, anyone else had a similar problem?<br />I've mailed Garmin and am awaiting a reply.<br />Thanks
