Question about Garmin GPSMAP 178C GPS Receiver

1 Answer

Garmin 178c turns off on it's own.

I have a garmin 178c map sounder and it is about 3-4 years old. It seems to power up alright, sometimes it will stay on for a little while, and sometimes it will turn off immediately. Is this something i can fix myself either a wiring issue, connection issue or do they need servicing? Thank You

Hi

Sounds very much like the wiring plug connections in the back, always overlooked but so important that connections are tight and contacting.

I have used the Gpsmap 178c for about 3 years now. Recently I have started be unable to find satelites, wass on or off. Once in a while it works. presently I get no satelites I would buy a new antenna...


Based on the problems I have seen with this unit the problem is the reciever circuit not the antenna, so you should consider a new unit, Garmin charges a fortune to repair these.

GPSMAP 178C Sounder GPS Receiver: My 178C will not stay powered up. I just replaced ...


I had the same problem with mine. It is caused by a crimped wire on the internal harness inside the machine. I opened it up and discovered that when originally put together 3 of the wires from the plug were crimped. One was broken off. The only way to fix it is to open it up, restrip the wires place a piece shrink wrap on before you solder it back and then make the shrink wrap flush with the back of the plug and heat her up. And, Voila... no more intermittent operation. Hope this helps? John

Garmin 178C Stays on for 20 secs then turns off


I had the same problem. In your settings you can set this thing to monitor your battery's power so it auto shut down if your battery goes below 11.2 volts or so. I disabled this and it has worked ever since.

I have a Garmin 178c map/sounder and it will not load up my BlueChart Data Card. I bought a new card, thinking that would cure my problem, but it didn't. I would love to get your input what steps to take...


I have the same problem. Did you ever figure out why it was not loading? There are no software adjustments to be made. Just plug in the card and wait. It says its reading the card, but never goes any further. Let it 'read the card' for hours with no luck. Help!!!
