I upgraded the boat this year. The new boat has a Lowrance hds 5 installed from previous owner. I like to troll a lot and I cannot figure out how to show how fast I am trolling. I found that I could add water speed as a data overlay but it is showing a speed of 0.00. Any ideas here? Do I need to purchase something additional to get the gps working? Any help is much appreciated? I am getting frustrated with figuring this out? Thanks

You might be able to get a better response from your state board or the main Utah board. I don't have an HD Lowrance but I do have an Lowance GPS finder and I think they about the same as far as your question goes. Go to pages button, hit it, then look at the top of that page, you should see Status\ navigation\map\ sonar. Click Map, then Map with Sonar andyou should be ale to see your GPS speed. Mine has the same problem as yours, I think that other water speed indication is only if you have a paddle wheel for you speed. The HD screen could be different but if it isn't that should work.

You can overlay the GPS data. Its in your settings menu, but you have to pay attention. Your HDS5 is set up to get two different speeds. One from a water sensor, and of course your GPS provides that data as well. The best thing to do is contact Lowrance customer service, and they'll walk you through it.
What you are describing is easily avoided by having a separate unit for sonar and navigation. I know hind sight is 20/20, but consider fixing the issue by installing a separate GPS unit. Lowrance makes a Elite 4M which is a color GPS ONLY. The only wires to run are the ones for power, and you can tie them right into the same power bank as your HDS5.
I only mention this because I have my boat set up with dedicated units, and always have. I've many boats where they have combo units, and i've found it to be cumbersome and too involved. I have a Lowrance Elite 7 installed for my sonar, and a elite 4M for navigation. Makes things simpler.

Thanks to both of your replies. I think my issue is the GPS is not working or a setting is turned off. I can get the gauges to display with the sonar and also add a data overlay for speed over ground (SOG) which is supposed to be GPS, but no matter how fast I go it shows as 0 mph. I am probably going to have to call lowrance or get a separate unit for GPS.
