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.

If the transducer is out of the water, you will not get a reading and see the flashing depth. You should hear and feel the clicking in the transducer when out of the water and working properly. Are you getting a temp reading when out of the water?

When I turn on the unit it will not read the depth only a blue screen and it will not let me switch out of auto mode or run the sounder test?


I know this is an old question but just ran across it. The 1833C/NT is a radar and chart plotter. It requires the external and optional black box sounder to have depth recorder functionality.

I have a garmin gpsmap 498, 4 yrs old. I have been loosing satellite reception. I have examined the coax cable- I do not see any issues. Where do I look?


Had same problem,,, you need to perform an "Auto-Locate" With unit plugged in but not turned on, push the Page and Power buttoms at the same time,,, continue to hold down the buttons until the "I Agree" message appears. Then release the buttons, agree by pushing Enter. The system will then go through an Auto Locate sequence that corrected my problem.

I would contact Garmin and get their price for a repair. Navigation is too important to trust to a repair that may or may not be correct. Just go to http://www.garmin.com and click on the support tab.

Thanks for using Fixya.com

A test bucket wont work, A 200 khz transducer will generally not work in anything less than 2' of water, due to surface clutter. If the transducer is working, you should hear it make a ticking sound.

When you got the 17000 foot reading was your range set to auto?

How is the transducer situated on the boat? Sometimes turbulence and bubbles from the hull can cause erroneous readings, including unrealistic depths, or no depth at all. Stop the boat and turn off the engin e and anything electrical to see if problem repeats itself. If it only crops up when the boat is moving then it is most likely the transducer location.

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.

Check the finder on the bottom of the boat and make sure the cable is ok?
