There are a couple of tide software updates available on Garmin.com in the downloads and updates section. You will need to register your product and download. It took me a while fumbling around before I could find the updates. I got some "no updates are" available messages but there are, so keep looking. If you have a newer computer, you will need to purchase a serial to USB converter too. I had the same inaccurate tide message and the updates fixed my GPSmap 168. ps. you will need the unit ID #, and the Garmin instructions are incorrect. Go to menu 2x, Systm, then hit menu again, and pick "software version".
I just fixed mine with the same problem. You need to plug it into the AC adapter and follow the instrustions on page 73 to restore the unit. Worked fine all day after I did that.
This may help. Mine has the GPS antenna build into the bracket at the back. I removed the bracket and the unit did not go into the error screen and the sounder worked fine. The GPS would not locate but it has not antenna attached so DOH!! I have orderd a new antenna with the BNC connector and will post if that fixes the problem. At this point I'm guessing its a blow GPS antenna.
I had the same problem and contacted Garmin. This is being caused by a software issue that started when the government updated the software in their WAAS satellites. The Garmin website will give you instructions on how to correct this but I have listed them below:
Power on unit
Press enter to get past the I Agree screen
Now you should be on the satellite page, press the menu button one time
Highlight WAAS off and press enter
By doing this, the unit should not shut down.
I followed these instructions and my 168 Sounder is working fine.
Some 235s had a problem with the contrast setting. When the contrast is set to full the screen turns black.
When you turn on the GPS and the screen goes black, try tapping the left arrow on the track pad a few times. You should see the screen start to lighten. If that doesn't work, tap the power key and try tapping the left arrow a few times.
