I recently bought a new Wide area cartridge, replacing an old Superwide, When displaying any chart off the new cartridge, the plotter crashes every few seconds. I also have a Local cartridge of a neighboring area, which works fine. The really wierd thing is that if I call up the new charts on my second (networked) plotter, the second one (displying the chart) crashes, NOT the one the chart is plugged in to. So I don't think it is a problem with the cartridge or the interface, more likely a format incompatability or memory problem??

i have lost my maps on the gold card Australia e&n i have not taken the card out of my lowrance gps sounder lms 339c since new some three & a half years can they be restored i have had no luck trying to contact navionics australia
you may know that this model of printers is very old
i think your cartridge is expiered try to change the cartridge if by the old one just to test....
if the new cartridge is the reason then you have to replace it
Furuno just stopped producing these models about a year ago. They use a special chart card. You can still purchase the cards from Navionics or C-map if you need to. I will tell you from experience that you should get your internal battery changed out if you havent done so already to keep from losing your settings and waypoints. The dealer will have to save them for you though and put them back on. Furuno made a GP7000 to replace this one and it's uses SDcards and is nothing like the rest of Furuno's product line. The best replacement for this unit is the Garmin GPSMAP 700 series. You can use your old furuno transducer if you have one (with an adapter plug). This garmin unit also has a built in GPS or you can use an external one. The 700 series will be shipped in April. Check out Garmin's website or mid-shore electronics.
Does the image come back by itself if you slow down or stop and wait? If not, make sure you are not leaving the coverage area of the chart you are set to. In the LCX-20, that Navionics chart is split up into several sections, if you have one section selected and are on the border and then leave that area, the map usually goes all white depending on your zoom level. If you are on a border like that you will have to learn to quickly switch the charts from the MAP DATA menu.
If the map does catch up when you slow or stop, and just can't redraw fast enough...
Make sure the LCX-20 has the latest updates which can be downloaded
from http://www.lowrance.com/en/Downloads/Product-Software-Updates/ These updates often add additional Navionics support.
Most likely though, this is just going to be the way it is with that particular map and the LCX-20. If you zoom out it will be much much better. So if updating doesn't help, zoom out. Experiment to see how close you can be zoomed in while running above 20mph. If you can get a good zoom level to where the map can keep up and you can still see the information you need then you should be good to go. If not, use the LakeMaster card or go get a different mapping option...or upgrade your display unit.
If both plotter works but they have no comunikation
RESET the RL 70 AND L760
This is how it works
press the powerbutton when you have picture press the menu bottom
than systemsetup and than four seconds the menu bottom.
Do this on both plotter normaly after this it works again
It depends on what model you have. Most chartplotters require a chip with regional chart data. Most Lowrance models use Navionics charts. If you have a chip in the GPS, go to the map screen and press the "menu" key. Somewhere in the map setup menu will be a field where you can specify which chart to display.
For example a Navionics gold chart may cover the entire east coast, but it is broken down into a few sub regions. If you are boating in New England you would select the sub region labeled Northeast. Some of the earlier models didn't name the regions, they used model number for each region such as "XL904G". In that case your best bet is to try each one until you can view the charts in your area. Zoom in to 1/2 mile scale to make sure you can see charts.
If you have done all that and still can't see the chart details, there is also a setting in the map setup menu that allows you to set the level of detail. Make sure it is set to normal, more, or most. If you see a declutter setting on the setup menu, try setting it to off.
There is a feature in these chartplotters called "Plotter Mode" that is often misunderstood and causes the exact problem you describe.
Press menu.....chart setup.....and scroll to the bottom until you see Plotter Mode in the list of options. It should be set in the OFF position.
If you have more than one display networked onboard check the setting in each one invividually.
What Plotter Mode does is allows the chartplotter system to access range scales not supported on the chart. It is not normally used for map-based navigation but more so for chartless electronic plotting (it can display routes, waypoints and track-recorder breadcrumbs.) open-ocean cruising, or for ultra-precise GPS operations (like a precision anchor drop, finding a very specific location etc. When plotter mode is on you can zoom in to a very, very small working area. The indicator it is enable is the cross-hatch background on the screen, the lack of map information, and the NO CHART DATA watermark on the screen.
