GPS module not responding

[Klob]

Has anyone else had this message on their Lowrance? Laterly mine has been going off more and more, randomly. Not sure if its the head unit or the actual module. Unit is a 337 and up to now has worked quite good.

I had the same thing happen to me last weekend and again this weekend. I have the 110c. Think it is a satalite issue? I checked all the connections etc. Such a **** off!

Could be the fuse holders, as they seem to cause an interment power loss to the GPS puck. Fire up your system and wiggle the wires. If you get the error message then you know you have a wire problem. If not it could be time for a new puck.

Sorry to say but most of the time its the atena going on the fritz early warning sign try a new one and test bet you will be ok

We have been using the 332c for the last 5 years, and have had a number of the pucks go, but quite often it is the what GLC mentioned, low power to the GPS modual. Dirty fuse or connectors can be the cause, along with a weak battery. We have had a number of the T-connectors go also, especially after a cold winter, as if there is any moisture in the connector, it will freeze and crack. The 332 and the 337 are the same unit, just the 337 has a dual fequency transducer. If you need, you can bring the unit by and we can hook it up and see if it is the head or the gps puck. Good luck.

It is most probably not a problem with the GPS satellites - if it was it would be huge global problem and you know about it in the news, etc.

I have had some experience with this error message on Lowrance products. Here are some things to check out:
- power supply must be at least 12.5 volts all the time,
- if applicable do you have the lastest s/w upgrade installed?
- are all connections to the unit clean and sound?
- especially check the male & female connections that you connect/disconnect frequently as these can wear loose over time,
- your GPS receiver antenna may need to be replaced depending on how old it is - they can wear/crap out,
- if it is not properly shielded it can be knocked out by ship's radar. If it doesn't have a shielding sticker on the bottom, then you may need to get a new puck.

Good luck! (I hate intermittent electrical/electronics problems they are a royal pain in the butt!)

Before doing anything - Check the connections between the boat power source and the unit. Use a voltmeter meter and make sure the reading on the boat and unit are the same. If there is a splice or connection "between" the boat and unit, make sure you check that both going in and coming out, that is a commonly cause of the problem.

Charlie, PM sent on another matter. thanks for the info above!

The antenae is on its way out, I had the same thing happen. Island Fish Lifter on this sitehas an antenae he may part with if you havent already got one.

I dont think Ill part with it, sounds like theres a good chance I may need it. I cant afford to have that thing go down on me during the season.

Dont't blame you...sounds like you need to have a spare in case!
