Humminbird issues?

[apb]

I am very close to returning the Humminbird 597 ci hd di.  I have been having allot of  problems with it not reading the correct depth...it flashes back and fourth to correct depth,  0 to 2 ft, 1000ft etc...the sonar graph is a total mess also...  especially when beyond 150 ft. The salt water setting is on deep.   Now I cannot get any GPS speed, maps or waypoints  at all.  Does the GPS speed have to be programmed in or should it come on automatically...  Thanks,  Andy

Speed should be automatically however it doesn't show on every view. Try resetting back to factory settings and then go back and change to salt water deep

Thanks but I tried that...I cannot get GPS speed,  maps,  waypoints or any of that.

I would try contacting humming bird sounds like the GPS is not picking up satellites. Maybe a software problem and they might send you software that you can install using the SD card.

The only other thought I can think of is to make sure it is set for the internal antenna and not the external.

Otherwise I would contact the factory. They helped me when I had an issue.
