H2OC Won't aquire satellites

23 posts in this topic

Has anyone else had the problem of their GPS not aquiring satellites and what Lowrance suggested. My H2OC couldn't find them for the first time ever this weekend. I tried the older h2O and it got them fine. I'd really like to not have to send it in or get another one, since I've got all my points/trails saved on mine.

Thanks,

Nick

nolte, even if it doesn't read satellites, and you have to send it in. You can write down all your way points frown and re-enter them in your old one. Just hit work inside since it will take a while to do it. Good luck.

I have had issues with my H2O aquiring also. I had installed a RAM mount on my boat's console for it, but had to move it because the windsheild seemed to be blocking the signal. Same thing happens in my truck, so I have to hold the unit out the window above the top of the cab to get it to lock on.

Yes, one day my H2Oc would not show my position, however it was communicating with satellites! It was a crystal clear day. I was in the middle of the lake, no obstructions at all. I spent hours trying to get it to work to no avail. I did find my spot with a Garmin auto GPS in the truck (I could enter coordinates into that grin)

Ever since that one bad day about a month ago I haven't had any issues. I've used it a lot since.

I have had mine do it a couple times where it wont acquire a fix but it will show that it has many sattelites with good signal. A couple things I have done to get it to acquire. 1 turn off remove batteries, replace and retry. If that does not work. go to the gps setup menu and select initialize GPS. floow the instructions and it should acquire a position. It seems sometimes they get confused or something. I think eventually they will acquire on their own but one of the times it happened I waited 30 minutes and still nothing till I did the remove batteries thing. After that it took 30 seconds to lock in.

I can't help you with it not locking on, but if you do need to send it in or replace it you don't need to write down your info to transfer it, you can use a blank SD card and transfer your data to that.

I have also had the same problem. Found that by zooming it all the way out it picks it up quicker. Then zoom in as far as you want!

Eyebjim--Is right in my experience. I don't have a hand held unit. I soon as I played with the power cord it worked.

Make sure you aren't in "external antennae" mode. If nothing else works, download your points to an SD asd send it in and wait...and wait...and wait. Mine took about 4 weeks but they sent me a new unit. Hopefully it doesnt happen again.

I thought there was a hard reset or initialize process you could try to fix the problem.

Anyways, believe it or not there are some spots/conditions that will cause problems. Early this winter up on Elephant Lake near Orr a bunch of us were up there and not a one of us could grab and hold a satellite signal in the middle of the lake. It was weird for sure.

I have found very cold weather to be an issue from time to time, and when you go a long ways from the last time you used it, it has to find it's spot again. Also check in the setting what map datum zone area you may have it set to? There are some better then others.

It happened to me also, but mine was brand new. Well after 2 months and about 100hrs of being put on hold they sent me a new one. I am sure glad work paid for all the long distance calls:)

some times you have to be moving to aquire a fix. even tho there are trackable sattelites they may be in areas on the horizon which cause low accuracy. But remember your working with a computer, commons sense answers dont always apply. laugh

I've found, sometimes if you zoom in as close to where you think you are it will pick it up quicker

I have the black and white unit and never had an issue. My neighbor though has the color and takes a long time to get satellites. We notice that they run a different software so I wonder if that is the reason. Even checked to make sure they are running the newest version of software.

I had the same issue. I would be going down the road and all of a sudden I would not have any sat. I had a friend of mine send it in and the sent me a new one. Mine was about 3 yrs old.

I had an H20C do that when it was 18 mos old, so I called the manufacture (and sat on hold for quite some time). We tried a few things (software version, re-set etc) and the manufacturer instructed me to send in the non-working unit with a check for $162.45. (which I did) The replacement unit will have a 6 month warranty. This was last week (3/26). I am curious to see how long the replacment unit will last.

Try the hard reset (you will have to call Lowrance or look in the manual if its there I don't know) and also make sure to update the software to the most current version. I buy all my products from a place that will do free updates for all my electronics. I think these are also available through the HSOforum.

You can do either a "soft" reset, or a "hard" reet. If you do a "soft" reset, it should not erase waypoints or trails you have saved. (note - it "should" not erase; I'd still save my stuff to an SD card before resetting). A "hard" reset will erase your saved data. Not positive about the H2O, but on my 334C GPS/Sonar unit, you do a "soft" reset by holding down both the PAGES button and the power button when turning on unit. A "hard" reset is done by holding down both the zoom in and zoom out buttons, plus the power button when turning on. If successful, a map display showing the whole US will appear. All software options choices are set back to factory defaults with either type of reset. I've had to do a "soft" reset twice in 3 years to "fix" problems/corruption of the operating system. It worked.

My old H2OC has issues too. It will not lock onto sat's. It communicates with several sat's but will 99% of the time it will not aquire my position. This all happened right as I was leaving for a fishing trip so I saved my waypoints to a sd card and bought a new one before I left for the trip. I held one in each hand on the lake and the new one worked and the old one didn't.

I have not sent the old one in because the warranty had ended and I thought I just got a lemon. Does anyone know how to do a "hard reset" on these units? Anyone sent anything to Lowrance that was out of warranty? If they'll fix it cheap I'll just have a spare I guess.

I recently exchanged the unit with the manufacturer, the old H20C was out of warranty (2007). It took about a month and the cost was $162.45. The replaced unit has a 6 month warranty and works (so far).

There are a number of self help troubleshooting tips on the manufacturers HSOforum. I also called their technical support department, and the hold time was around 30 minutes I suppose. Perhaps future competition from other manufacturers will force this company to answer their telephone in a more timely fashion, maybe all of the manufacturers provide this level of service, I am not sure.

I ended up getting a RMA# and sent in the non-working unit with a check.

I am not 100% certain if this was worth it or not, time will tell.

Mine too has a problem locking in. The difference is that it has been happening only on days that are clear and sunny and only during the middle of the day. It works fine in the morning and after dinner and also works on cloudy days.

    • Butt the 2 sheets tigh and leave the gap against the side walls of the boat where it will be less noticeable and get no foot traffic . A thin strip of aluminum riveted or screwed on the underneath side of the plywood helps to hold the seam tight
    • two bowls of that will send you to heaven!!
    • 10 IN THE BOAT HERE ON HIDDEN BAY early this morning. Can’t sleep so I got up and made a breakfast and rolled myself into the den to look at my mess. I am in the middle of a computer upgrade when my new addition decided to die on me. Not a new computer but the daughters old one which when running is ten times the old junker that I have been running. We have narrowed it done to the power supply but I am going to have my x son in law take a look before we do anything. If my den is not all ready crowded enough with a cluttered desk and tobacco out to roll some cigars and the trays of flowers under the grow lights there is just enough room for me and my chair.   So I hitched a ride yesterday afternoon to the Lodge with my neighbor Chuck. Place was quiet so I was actually working going over sales the last week and plotting sales when we had games on the new TV and sales are up. We will have it paid for here shortly and it might even make us money this summer if the Twins can put any kind of a season together. So I am at the bar and a older gent walks in that looks vaguely familiar. Looks the place over then takes a seat on a stool in front of me "HIYA" he says and I return the greeting. "Where are the dogs" he asks. I sit back in my stool and ask "You mean Bud and Barney?" He nods his head yes and says "It has been awhile since I have been here but I do remember being greeted by two big brown dogs" " They both passed a few years ago." I said. He nodded his head and said "Sorry for your loss" and we both just sat for awhile thinking of old dogs.   "My name is Luis" and he put out his hand which I shook. "Got a place on the end of the lake and this is a long drive to get here but I decided to make the drive today" "Welcome to the Lodge Luis" I said then I yelled out "Duncan" and Duncan got up from the couch in the office and came out to the main room. "Say hi to Luis" Duncan then came around to Luis, sat down and stuck out his paw to be shook. Luis chuckled some and shook Duncan’s paw and looked back at me and said "I figured you would not be dog less" Some petting and a few good rubs and the two of them were now long loss friends. Duncan came around the bar and laid down on his rug by the cooler.   "So what can I get ya Luis?" Luis looked at the back wall and said "You know it looks like a beer day, How about a Hamms?" So I poured him one and a shortly for myself and went into my bartender mode. "You have a dog Luis?" I asked. Luis wiped his mouth with his sleeve and smacked his lips. "I don’t but my wife does. "What kind ?" I asked and Luis told me he does not remember, it was expensive though and it is retired. "Retired, I asked, How old is it?" Luis taking another sip of his beer said "Two"   "How can it be retired already" I asked. Luis looking into his beer glass said "Well the wife carries it everywhere, dresses it up in spendy dog clothes, It fits inside her purse and she takes it shopping claming it is her companion, I thought I was her companion" Luis held out his glass for a refill and I poured him another. We spent some time talking about hunting dogs and big house dogs and dogs that never see the inside of a purse. I sat on my stool behind the bar with Duncan’s paw resting on my foot, I guess it aint all that bad here at Lake Iwanttobethere
    •     Sounds like Trump wants to run it like the DNC and the GOP run the debates, only minus the DNC...      
    •     Yes, that's what I was thinking.....    
    •   Rush was getting the pills from multiple doctors and off the street, which is punishable by up to 5 years in prison..  But, of course, he had the financial means to avoid prison, whereas the average Joe does not.   Ending the war on drugs means getting the federal government less involved with drug abuse, since they have failed miserably at the job.   States like Arizona and those going ahead with legalizing marijuana as a first step are taking the lead, and eventually the feds will have to step aside.   http://substanceabuse.az.gov/substance-abuse/rethink-rx
