Lowrance GPS module "Not Responding" ???

[CrossinEYES]

Just installed my new 110C with GPS and the only thing it says is "GPS module not reponding". I have checked and double checked ALL of my connections and have went over the installation etc. but I am having no luck. I am at the point where I feel I am overlooking something simple but am pulling my hair out trying to find it. Any help is greatly appreciated. Is it possible that my gps module is defective? The 110c comes on and works perfectly, even tried plugging in my 332C with no luck!!??

FISH ON!!

Did you get power to that new GPS antenna?

The new ones need 12vdc.

[CrossinEYES]

The book says it still uses the LGC-2000 module. I hooked it up the way the book shows. Do the NMEA 2000 power wires have to be hooked up as well as the power supply wires?? If so, this will probably be my problem..??

[ackermannsacre]

The book, the NMEA booklet and the red add in sheet all tell you to hook up the red, black and shield wires from the NMEA power cable.

[Eric Schuelke]

The GPS reciever needs to be connected to a power source.

[K Gonefishin]

Me and my buddy same thing, there instructions suck you need to power the moduel itself, i have seen this post 20 times or more

[Prowler]

Had exactly the same problem with my 332C. The secret was to hook the shield wire in the NMEA 2000 power cable to the GPS module to the negative (-) wire. That provides the ground.

I posted about this a few days ago, same issue with my 111. Lowrance forgot to put a note in the new manuals that use a NMEA 2000 antenna that says it must be powered. I also found out last night that if the antenna is wired direct to the battery the antenna draws about 40mA, even with the power off on the unit. If the antenna wire is disconnected from the unit the antenna quits drawing current. I plan to put a main power switch in the line so I don't have to disconnect the antenna all the time.

I have a brand new 3500C and the GPS module that was shipped with it did not work. But, I'll bet your problem is no power to the NEMA wires.

What is going on with your 3500 that the GPS puck doesn't work? I just got a 332 to replace my 330 and found that I needed to put the puck farther from the unit or the puck would not work correctly.

I am waiting for my 3500C to be delivered.
Needless to say, I am VERY interested in this "thread".
Please continue posting your advice / tips / tricks, on how to get these "new" GPS units and receivers working properly.

Thank you.

I was out yesterday and my lms337 did the same thing again but mine would go in and out. Saying gps module not responding and then I would get a signal. Just wondering if there might be a loose ground or something. Jason

[reelman1]

JasonW, this is exactly what mine was doing until I moved the puck farther from the unit. Try moving the puck a couple feet away and see if that helps.

Interesting regarding the power draw Netminder. I've been trying to figure out for months what is very slowly draining my battery, but never thought about the GPS antenna module. I'll have to throw a meter on and disconnect it and see if that resolves the issue.

Thanks!!!

Checklist for new units with LGC-2000:

1. BOTH power cables need to be connected, 2 black, 2 white.
2. The shield wire also needs to be connected to ground.
3. The NMEA wires (multicolored set) need to be taped off properly if not being used.
4. Lowrance suggest a direct connection to the battery. Check the manual for instructions.
5. There is a small draw from the GPS antenna even when the unit is off so you will need to rig it accoringly.

If all else fails, give the Lowrance techs a call.

Wade; there is no white wire in the NMEA2000 power cable only RED, BLACK & SHIELD. Also the main power cable only needs to have the RED, & BLACK wires connected to the battery. The WHITE wire is for an external speaker hookup.
Also to clarify a point I made in my previous post, the antenna does draw approximately 40mA. This is only for units that use the new LGC-2000 (Powered Antenna). All of the previous Lowrance units do not require power for their antennas.

Thanks for pointing that out. I got careless there. I meant 2 black 2 red (not white). Both sets of power cables need to be connected. This is the most common mistake we're seeing. The NMEA wires should be taped off if not being used. The shield wire should also be connected to ground.

Just brought my boat back from the dealer on Friday after having a X-20 installed.I read this post and went to try my unit and guess what? I get the message GPS module not responding. Thanks to the info. posted here I got my X-20 to work in short order.Thanks Walleye Central for access to a wealth of information.

[andrew]

My globalmap 3300C has the same problem, it was wired correctly and I have had the antenna,wiring and finally the head unit replaced and still it drops out intermitently. I have taken it out of the boat and connected to my car battery and it still drops out. I have been told by some dealers they have had problems with faulty head units. Any one else heard of this?

[Wade@JollyAnnMarine]

Andrew, It could be another bad unit. That's always possible with electronics. I can tell you that we had very few problems with the 3300C last year but there were a few exchanges needed. Check with Lowrance to make sure everyhting that can be done has been done.

Just got my third head unit from Lowrance in 2 months, seems to be working at home , will take out boat this weekend fingers crossed...........

[TroyC]

Well, I've been working on the problem for 3 weeks now, talked to numerous people at Lowrance, and it is tough to get the correct answers. I am trying to run 2 units, (X-20 and LMS-332) off of one 2000 Module. Something must be wrong. At time I can get both units to read off the antenna and at times I get the "GPS Module not respoding" I have both units powered and both units powering the network. I have the NMEA 2000 expansion cable to be able to do this. Last night, I had the main unit receiving the signal and as soon as I turned on the second unit, the signal was lost. Something is not right here. Do I need to get a new module, is there a short. Anyone else trying to run 2 units?? I'm ready to throw the units in the water!

Troy

I will guess that the master is the X20 and the second 332 is a slave, remember that sonar uses a Communication ch just like a diff beacon. In the old days you had to disconnect sonar to use a diff beacon. might be using up all com channels cause its sharing. Try disabling the sonar in both units, just set them to off and unplug the sonar transducers and try it again.

Thanks for the help. Just installed my LCX-110c and got the " GPS Module not responding" It was a power problem.

[FAT_ CAT]

I have one of the early LMS330C units and had problems with the unit recognizing the GPS antena. The problem was traced to not having the network powered. The manual overlooked this requirement. You have the network powered according to your post but you might be causing a problem by powering the network with both units. I would suggest you try powering the network with only the LMS 332 and see if that eliminates the problem. Good luck!

[JIGGINGFOOL]

Had the same problem hooking up my new x-25c and showed not responding. Was about to box it up and ship it back to get fixed but called Lawrance support and they told me to hook the other red and black wires to the battery also and that would fix the problem and it did. I have a x-15 that don't need the extra wires to make it run, I don't know why that made it that way but I'm sure they did it for a reason.

Thanks Guys! A friend forwarded this to me as he knew that I had just bought a 110c. I'm still in the process of running the power wires for the unit so I haven't yet got to the "GPS module not responding" message. Now I know that I'll have to power the 2000 module also. You just saved me a bunch of frustration.

Ok, a question. I'm planning on using the LCX-110c as a master unit and a LCX-104c as a slave. I'm planning on connecting the two units via the NEMA 0183 com port. If I power the 2000 module as suggested in this thread, will I still be able to NEMA 0183 connect the 2 units?

Thanks!!:)

[dockehr]

fishpoop,
if I were you I would contact tech support at Lowrance. The LCX104c uses the LGC-12w antenna and NMEA 0183 protocol. The LCX110c uses the LGC-2000 powered antenna and the NMEA 2000 protocol. I don't believe that the 104 will work off of the LGC-2000 antenna.

Good luck and good fishing.

The newer units (with LGC-2000) also have the NMEA 0183 output so it can be done.

Dockehr:

Your're right as you state your reply. The 104c wont work with the 2000 module. But what I'm trying to do is connect the 2000 module to the 110c (master) and then send the signal from the 110c to the 104c (slave)via the NEMA 0183 connection, which the 110c has in addition to the NEMA 2000 connection. The NEMA 2000 connection won't be used in my configuration. I'm hoping that this will work. I hope that this clarifies what I'm trying to do.

[fishpoop]

Wade:

Thank you for your reply. It should work, but if it doesn't I'll post to this thread and let you know.
