Is it out in the open so you get a signal? You can restart it like it was brand new.

My 334c did pretty much the same thing, it was positioned at the last place I fished and kept losing signal. I'd leave the cross hairs up and manually go to where I was. Kind of a pain but it was usable. Like Charley said, make sure you have a clear shot to the satelites and if all else fails, give Linda Colt a call at Lowrance.

Pressing the exit button will bring the map to your current position.

If you're getting the message "GPS module not responsding" that means it's not getting power from your battery. Check your connections, fuses, switches etc to see why it's not getting power.

i believe the gps module has its own power source and could be loose...possibly try a soft reset..when unit is off hold in the pages button and the power button at same time till units starts up and map of the usa appears..

You could also try "initializing" the GPS. Make sure the GPS map is up on your graph and then hit the menu button. I don't recall exactly where this option is at in the menu structure but look for "Initialize GPS" and then follow the on-screen instructions. What you will do after selecting this option is move the cursor using the arrow buttons to your current location and then hit the enter button. This helps speed up the acquisition of your current location.

Typically when you turn the GPS on it will look for your last position where you shut the unit off which helps speeds up the process of acquiring a satellite signal. This is fine unless you travel a long distance away from your last spot where you had the GPS on and then it has to search for a while to find your new location.

If this isn't the solution, go to the satellite signal strength screen and look to see if the unit is locking on to any satellites. As PerchJerker said if you get the "GPS Module Not Responding" message then the GPS puck does not have power or the communication circuit is bad. Check the fuse and check the power to the puck. If both of these check out it's possible your puck is bad.

For that Lowrance unit you need power to the display head, and power to the "network" ---- even if the network is only a GPS puck. If the message "GPS Module Not Responding" displays on the screen it means the network ie. gps puck is not getting power.

Spin Dry - if you have a master power switch try turning it off and on. I've seen it happen where the switch will get bumped and it's enough to shut off the electronics, even though the switch is still on. Flipping the switch off and on cured it ---- kind of a stupid / easy fix but go with it if it works.

I suspect the GPS power or the puck receiver connections. Start there.

If there is a added fuse link on the GPS power line, check the link for tension on the fuse and any corrosion, or a blown fuse. Light corrosion on fuse links often after extended storage may cause complications of low power, and unusual shutdowns of the electronics or low power causing programs to not function properly.

Fallow the power, check all connections.

It was the power. Of course it was under the floor. Had the dealer install. Thanks for the help.

    • LOL Then YOU my friend are the one who jumped to conclusions in your last post because that was a direct quote from the post you were replying to. You did say it was NOT a joke, right?
    • Finally saw a few divers myself today.  In town.    Yah, I don't think it would make much of a difference if they let us just keep going.  
    • Whoooaaa...slow down big fella. Of course I do not think one party is any more "evil" than the other.  I don't think ANY of them are evil, they just have, more or less, different basic principles. You my friend,  have some serious attitude problems and seem to be very prone to jumping to conclusions and letting your paranoid tendency's run away with you. I have many friends on both sides of the two MAJOR parties and have worked with a couple of genuine Libertarians too. I can only recall a couple individuals I would consider might be "evil" in your sense of the word. Shucks,   I don't even think YOU are evil.   Ha Ha HA!
    • Salami ready to eat. 1/2 goose.....1/2 beef. Much firmer than using pork.Love this seasoning. Garlic, smoke and peppercorns. I always add extra garlic to it. Lately I have gone to using powdered smoke. 1 tsp. per pound of meat. Gives me a consistent flavor every time. No guessing how much smoke to have. Also allows to use the oven inside instead of out in the cold.   Summer sausage in the oven now while I watch football.  
    • --------------------------------------------------------------------------------------------------------------------------             You might want to read what was actually typed:     Do you really believe your side is good and the other is evil? If you do, that's the part that is a big joke.
    • below is a link for doing pork loin jerky. you can use any whole meat for this.       click here :)
    • Nice conspiracy theory.  So how come after they tested additional thousands of deer they didn't find any more, if they were looking for an excuse?      What were you expecting as far as policing the borders?  How many folks would be necessary, and how on earth would they do it?   But whatever.  You sound just like those guys back in the day over by Madison Wisconsin that had big money in their deer hunting land and raising trophy bucks.  No way were they going to kill a bunch of their deer.    And look at it now.  30 percent infection levels.     It's like AIS.   They are doing what they can within the limits of budget, manpower, and politics.     Look at the map of cwd infested counties in Wisconsin... I posted it up above.   Do you want Minnesota to look like that?  Do you want to eat deer with CWD?
