Need help - ifinder H20C won't read new Navionics chip

Question

just_jig

If anyone has any ideas I am all ears. Just bought the Nav Lake of the Woods chip and my GPS won't read it. I have the Lakemaster chip and it reads this great. checked map data to Navionics map choices and Navionics is not listed. I'm thinking I got a bum chip. Any ideas?

I had a problem with an older Navionics LOW chip. What I figured out was I had to put the chip in when my GPS was already on. If you're running your H20C on battery, this will be impossible to do because of the design. If you have a power cord that came with it, run it off that, turn your H20 on, and then pop the chip in. If your GPS doesn't beep or doesn't display Navionics under the map data, then your chip is unreadable.

Either way, you shouldn't have to do that. I recently upgraded to the Premium North chip and that reads fine.

Tried it, no luck that way either. Unit didn't even beep when inserting the chip. Has to be a bad chip.

May be a bad chip. There were a few out there. Take it back to the place you got it with your GPS and see if a different chip works. If not they should be able to show you how to get it set to work right.

Is your H2O in advanced mode? It needs to be in advanced mode in order to read the new Navionics. If its in easy mode then it won't read it...

also the new navionics chips in a h2o has to be told that you want to view it go into the map data area and you have to reconize which region you want to see and enter it for your unit to read it..just highlight which region you want and hit enter and it should work..there might be a few bad chips but i bet that this is your problem..now if you would have got the lakemasters chip it would have read it right when you turned it on...hope this workks for ya..

I've got the iFinder H20 and it worked great. I bought the Navionic's LOTW chip and took out my LakeMaster chip to insert the Navionic's chip. When I went into Map Data -> Map Choice I only see the Lowrance option and the Miami Demo. So I thought I got a bad Navionic's chip, so I took out the Navionic's chip and put the LakeMaster chip back in and now I can't view the LakeMaster chip. I've got the chip in correctly, I've even reset the device the factory defaults and I still can't view either chip. Can anyone assist? I tried to call the Lowrance support line but there only open to 5 p.m, makes it difficult when I guy has to work until then. Grrr! I'm leaving for Canada in couple days and I need this baby to work. I appreciate any help.

Thanks, Matt

Matt and others, hopefully you can help me. Have had Navionics Premium North since 2004. Has worked fine in h20 and Eagle 642c. On advice of Navionics rep (and good advice, so not complaining there) I updated the Lowrance/Eagle software on h20 to the latest v1.5.0 software. It went fine, and it works fine.

But the problem now is that when I use the Navionics chip (and it is loaded properly to correct map data) it no longer gives me the nice detailed map contours that is should, and that it had been giving for years. It is simply an ugly outline of the lake, with some contours, but no numbers and the contours look like a kids etch-a-sketch. No kidding.

I place the same chip in the Eagle 642 and the lake looks beautiful the way it should. I do know how to use the h20, and I even reset it to default settings, to see if that would help. No dice. It just seems like the v1.5.0 software hates my 2004 Navionics Premium North.

Any suggestions? As the chip is fine. Tomorrow I will try my Lakemaster chip on it and see if that works properly. Thanks for any suggestions,

Box,

I'm not sure why that would cause your maps to get ugly. I would call Lowrance or check out there support site online. I called customer service today, my device will no longer read any chip so I have to send it in and it's a 4 week turn around...grrr! I leave for Canada in four days so I'm heading back to cabela's to see if they will exchanget he device since I bought it less then three months ago.

Hey all, just wanted to post that my issue was indeed user error. I figured I had some settings wrong, but in the end I had the wrong map - exactly the thing "I" said that I had correct - doh! Stupid users (*me*). It is working and looking normal again, the way it should.

What confused me was that normally when I pick the wrong map, no lake shows up at all. This time, an outine of the lake in question did show up, even though I was in the wrong map data. I should have known after using it for years already. Oh well, stupid me. On the Eagle 642c the map choice is much easier than on the h2o, as the regions are named instead listed as "reg09b.dat" etc.

Hope your unit gets back to you quickly, or that the store will exchange it so you can use it. That stinks if you can't. Sorry for my mistaken issue here, all is working on both Lowrance and Navionics side, despite my dumb user error smirk.gif

Box,

Maybe you can help. I got the device replaced last night, the retailer let me exchange it so I have a brand new iFinder H20. So now I can see the Navionic's chip when I go into map data and choose seul.nv2 in map choice. But when I look through the list of lakes I don't see Lac Seul? And none of the lakes show up with the lake bottom contour mapped out. The chip that I have is the Lake of the Woods + 2K, I must be doing something wrong? Any help is appreciated.

Thanks, Matt

Hey Matt,

My chip is different, so I am not sure what map you should check, but I would work through all the maps, and zoom in to see. The naming in my chip is not that great, and possibly yours as well. I.e. we would assume the "seul" is what you are looking for, but it could be "south east upper lake" or something like that. So check each one.

I ended up figuring it out but it wasn't easy. You can't pull the lake up by name like you can with LakeMaster. You have bring up the map of North America and basically zoom into the location of the lake and Lac Seul didn't show up until I zoomed in pretty close, I wasn't impressed. Thanks for the help.

Matt

      Do you have any tips for fishing Fish Lake this time of year? I'm gonna try it out in the next few days... Is it typically an early morning, late evening bite or can you get them all day long? Thanks for any info.
    • PRO-V
      Calling them would be your best bet. Maybe you can reserve some on a card.

      starft you off.... https://www.dnr.state.mn.us/lakefind/lake.html?id=69066000 http://files.dnr.state.mn.us/lakefind/data/lakemaps/b0537011.pdf Status of the Fishery Ely Lake is located approximately 2 miles SE of the city of Eveleth. This popular lake is highly developed with homes and cabins. There is a small seaplane base and two public swimming beaches also located there. Water clarity is good and large amounts of aquatic vegetation can be found throughout the lake. 

      There is a concrete planked boat ramp and dock located near the NE end of the lake off Cedar Island Drive (CR629) for public access. The parking space is somewhat limited near the ramp. Several private accesses are also present. 

      Thirteen species of fish were sampled during the 2017 survey on Ely Lake. Gill nets, trap nets and night electrofishing were all used to sample the fish community. Small bluegill were common in the gill net catch (34%) and abundant in the trap net catch (57%). Other panfish species including hybrid sunfish, pumpkinseed, green sunfish and black crappie were also sampled in good numbers. Largemouth bass outnumbered smallmouth bass in the 2017 sample. Walleye (16%) contributed to the gill net catch and several were sampled in the trap nets. Yellow perch are present in average amounts and some good sized pike were again sampled during the 2017 survey. 

      Bluegill numbers in 2017 (72.1/trap net) were much higher than the long term average (31.6/trap net) on Ely Lake and greatly above average (7.9/trap net) compared to other similar lakes in the area. The average bluegill sampled was 5.6 inches long and about 6 years old. Approximately 66% of the bluegill sampled with the trap nets were under 6 inches with a maximum size recorded of 8.0 inches. Bluegill sampled with the gill nets had a similar size structure. Approximately 7% of the hybrid sunfish sampled in the trap nets were 8 inches or larger. Several pumpkinseeds were also in this size range. 

      Largemouth bass (92%) and smallmouth bass (8%) were sampled during the night electrofishing effort. The average largemouth sampled was 10.9 inches which is similar to the historic average of 10.6 inches. The biggest largemouth sampled was 18.5 inches. Approximately 33% of the largemouth sampled were 12 inches or larger. The average smallmouth sampled was 9.8 inches which is slightly larger than the historic average (8.4 inches). The largest smallmouth sampled was 16.8 inches long. Approximately 32% of the smallmouth sampled were 12 inches or larger. Largemouth bass were also sampled from the gill nets and trap nets in numbers above average. 

      Walleye numbers in 2017 (6.2/gill net) were similar to the historic average (6.1/gill net) on Ely Lake and slightly above average (5.0/gill net) when compared to other similar area lakes with walleye. The average walleye sampled was 15.5 inches and about 4 years old. Approximately 34% of the walleye sampled were 15 inches or larger up to a maximum of nearly 29 inches. Walleye fingerlings are currently being stocked during even-numbered years and in 2017 approximately 62% of the walleye aged came from years where stocking occurred. 

      Northern pike numbers in 2017 (1.1/gill net) were similar to the historic average (1.3/gill net) and below average (3.2/gill net) compared to other similar area lakes with pike. The average pike sampled was 26.8 inches which is similar to the historic average length of 26.3 inches. The largest pike sampled in 2017 was 35.2 inches long and sampled with a trap net.

      Yes they do. Many resorts are set up for summer usage. Understand you can't use your FH in the storage lots. Only in a summer use lot. You have to pay for it. The cost is in addition to your winter fees. Usually more $ but the season is longer. The county requires the resorts to have bathroom facilities within a certain distance. Mac's Twin Bay has summer lots as do many others. Hunter's Point is another. Doubt Brandt's is set up for summer.

      Sweet! Heading back up tonight through the weekend. Bringing the wife and little one this time instead of my buddies, hopefully the weather cooperates.

      Heading up Sat morning and will be looking for Shiners. Anyone know if the Gateway and/or Kab Outdoors have them in stock??    Thanks for the input.

      Hi Guys & Gals, My brother in law recently purchased a property on Ely Lake. All the boys are invited up this year on Memorial. Unfortunately nobody in the family has been on the lake before. I thought I would reach out to the pros here on the forum to see if anyone would be willing to give us a few tips on fishing this lake. Thanks in advance, Dan
    • crappieslapper
      Hey Forum, My brother in law just purchased on Ely Lake. Memorial weekend will be the first time on lake. Wondering if anyone has some experience/tips they would be willing to offer the Ely lake rookies. Thanks so much. Dan

      I made it out last Sunday and did some searching for walleye. The search didn't produce any walleyes, just northerns and smallies. The water temp on the main lake was 58-59 with the bays being about 5 degrees warmer. The people I have talked to have had similar issues finding the eyes. We missed some fish that left the shiner all chewed up. Most of the fish marked were out in that 18-21 foot range which seemed pretty deep for this early. It could have been Saturday's cold front that pushed them a little deeper though.

      SRJ - Thanks for the report.  I heard the bite was very-good to excellent, off the rocks/reefs, in the mud/sand.  I will be at the lake fishing this weekend.
