I have two issues with my Garmin GPSMAP 740s, and hope that the experts here can help. The unit was new last year, and these issues showed up once or twice year, but have been more frequent lately.
Occasionally, usually after a fairly good jolt, the unit will shut down and restart. I've checked and rechecked the wiring, connections, and fuse, and all appear to be good and tight. The unit is mounted on a RAM mount attached to the windshield support pole, so there's a little shock-absorption through the mount, but not a lot. Has anyone else experienced this?
The other issue appears to be related to the transducer. It's mounted on the transom, midway between the trim tab and the outdrive, aligned as shown on the installation instructions. However, when I'm on plane, the depth display will frequently begin to blink, and does not change. When I come off plane, it begins working properly again, and once in a while it will simply start working again when I'm still on plane. As best I can tell, the blinking starts after crossing a large wave, or the boat pitches at a somewhat steep angle. Again, has anyone seen this, and what (if anything) can be done to fix it?
Thanks in advance!
