Question about Garmin 200/50khz, 10/40deg, Plastic, Transom Mount, Depth, Temp

Sounder transducer? Hi expets, I have a Garmin 178C sounder/plotter which came with a duel transducer. An accident caused me to have the transducer replaced and I was assured it was a duel. It looked different to the previous one and they don't seem to have part numbers for me to confirm. When back on the water I could only switch to 200 or duel but not 50 so I presume it is a single frequency? Or is there something tricky I have to program into the unit? Or should I check the numbers on the cable or just buy a new one???

I believe like my own Garmin I have a 178 which is the mono version, same transducer though, you alter the frequencey setting in your main reciever set up program.

My Garmin 498C will not show the contore of the bottom or give me a depth reading. The GPS works and will show me charts but, not the sounder option though.


You need to check to see if the depth sounder transducer is connected or functioning. It might be turned off, the connectors may be bad or the transducer is bad. I don't have the 498 manual in front of me but I think there is a test function under the setup menu. I'd check my connections (the usual suspect) then run that.

Garmin tech support is pretty good/quick. So don;t be afraid to give them a call.

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 won't find satellites


It would appear that your Garmin has no clue as to where it is on the planet. I think a trip to the owner's manual:

http://www8.garmin.com/manuals/GPSMAP178CSounder_OwnersManual.pdf

might be your best bet to help initialize your unit. The info on how to graphically initialize your Garmin can be found on page 5.

Hope this is helpful.
Good Luck!

Garmin 178c turns off on it's own.


Hi

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

Depth Sounder does not display depth


I will see if I can get mine off the hull for testing. Still have found no procedure. Thinking about just replacing the sounder with another unit.
