My Furuno 1650WF GPS/sounder is having problems. After being on a while, it loses its GPS fix. Some times it gets it back after a while, but it needs fixing.

The only place I can find in the yellow pages or on line is Phantom Marine In Newport Beach.

Does anyone have any comments, good or bad, about Phantom?

Or does anyone have a better suggestion?

Thanks.

Bill is there a way to update your unit via your computer? We have a garmin gps at work here and we were having similar problems. Went thru the instruction manual and there was a way to hook it up to a computer and download the new satellite info, it fixed it right off and also added some cool functions! Otherwise I always try to coat any electrical connectors with dielectric grease, it keeps the corrosion down and makes any connections water tight.

this came up when I did a search, don't know if you tried it already, and I don't know if you are going to lose your saved waypoints ..:

"You should try to switch off the unit and disconnect the unit from power supply/batteries. Also disconnect any other units connected to it. Leave the system disconnected for 30 minutes. All the electric charges stored in the system should drain out.. It should do a soft reset itself, then restart it."

Hmmm?

I've unscrewed all the plugs and sprayed them with WD-40 two different times. The first time it seemed to fix the problem for a trip, but not the second time. But I didn't leave them disconnected for 30 minutes either time.

But every time I put the boat to bed, I turn off the battery switch. Shouldn't that do the same thing?

Yes I think when you turn off the battery it should be the same thing. Is there a soft reset sequence?

Not that I know of.

If unscrewing worked once..... it's probably a connection problem.... WD40 can build up an not help.... is there any sign of corrosion? I know on my boats - connections were always a problem............. good luck with it..
