Lowrance / Navionics Maps

[rjbathgate]

Hey,

This is a bit specific - but maybe someone has experience with Lowrance GPS units...

Mine is Lowrance LMS 520C...

I have a Navionics SD card for my GPS, with New Zealand maps bundle.

I used this memory card to udpate the unit's software to 2.5 via a PC (as per nstructions on lowrance's website).

I then returned the SD card to the unit and powered in.

It automatically update the unit, and software version now reads the updated 2.5.

However, none of the NZ maps load - when looking at the map view of the area, I just get my waypoints & trails, but no country detail.

It worked perfectly previous to the unit software update.

When using the unit to browse files on the SD card, I can see the root files Data and Overlay, and then 3 chart files (within navionics/charts) (8G055S.nv2, 8g160XL.nv2 & 8g170s.nv2) -- so the unit is reading / finding the card okay.

I've read that the unit should find maps automatically and load them from SD card...

Any ideas at all?!!! Much appreciated... and season's greetings!

Any b**gering around with the navionics card as far as I am aware totally screws it up. I always use a spare 36mb card to do updates because of this, as far as I am aware, correct info.
So you may have knackered the card........

feck.

I have all the files from sd card stored on my pc (copied them there as a back up incase something went wrong ha...)

Any ideas if I can restructure the sd card?

Cheers

Stupid question - you have "told it" to use navionics maps? the menu options will be something like Map Data / Map Choice / Map Name ??

You have just saved my life.

I feel really dumb... but to my defence, I did look at all the Map loading options... there was nothing to 'load' map data...

but then I remember an option to tell is which map to use... and it was using Lowrance built in Maps... not the Navionics NZ Maps...

Saviour!!! Thank you

Ah, well, lets just say you might not be the first person to have been confused by the Lowrance menu system!

Have you tried the menu for navionics maps and it worked?
The default settings when loading an update is back to factory settings so it could be the problem but several folk here have screwed up the card trying to copy the navionics files from the card. I would be curious how you managed it when others have failed, expecially as I bought two cards as I was under the impression you couldn't copy them!
As far as menus go I like my Lowrance kit but the instructions leave much to be desired.....

Yup, works fine -- when I set the map to use as Navonics (instead of default Lowrance) it all showed up again and I can see my friendly boat ramp once more!!

Whilst I copied the files off the card for backup, the originals were left on the card, untouched. So if I put the copied files on a new mem card, I would presume it wouldn't work... so luckily I didn't do any 'damage' using the Sd card for transferring the software update...

But it scared me, so i'll use a different Sd card for udpates next time!!!

Navionics are fairly clear about not using the Chart Cards for anything other than charts. I think you got (very) lucky. Reading the damn things in anything other than a Navionics card reader is supposed to damage the chart data. I'd be very interested to learn how you got away with it .

Have a very happy Christmas!

No idea...

I've read the Sd card in my PC before now too (just to see what was on it)... never any troubles...

But I won't do it again, just to be safe
