Question about Garmin GPSMAP 168 Sounder GPS Receiver
Have two gpsmap 168 that were in a boat with an outboard motor charging problem that suppied more than 18 volts. Both units would say Voltage too high then turn off. Now both units turn on but after a 30-60 seconds the screen goes to one solid thin line from top to bottom. the units will not turn completely off or turn back on. If you remove from power then apply power again the units will turn back on but 30-60 seconds later...same thing
According to Garmin technical support your thin black line (my problem too) is due to a change made by the goverment to the waas correction. Turn WAAS off. Software update coming (soon I hope)

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.
