I have a Lowrance LCX 25C gps/sonar unit. Two days ago I get a message "GPS unit not responding". Sonar works fine, but not gps. Checked power to gps antenna......OK. The strange thing is that the date and time (which originates from GPS) still displays accurately, but I'm getting no communication from any satellites.
I've tried everything I know to do.....next step is to call Lowrance. Any of you had this problem or tell me what I might be able to try? Any help appreciated................
