This is a common problem with Lowrance products. Unfortunately they only service their product for seven years after prduction date. You might check with lowrance to see if you can get the unit serviced but most likely you will need to replace the unit.
I think you have a C- Map card (black colour)clean the contacts with a contactcleaner if it not works try the card somewhere else
The C-Map card have problems that they work for a while and than stops inside the card a some memorychips and they losing contact
I am guessing that the card you are using is a NAVIONICS chart? There have been some Lowrance units that were made around the same time that have had problems recognizing a Navionics chart right from power up.
Make sure the LMS-332 has the latest firmware version which can be downloaded from http://www.lowrance.com/en/Products/Marine/Full-Size-SonarGPS-Chartplotter-Combos/LMS-332C/Downloads/LMS-332C-Software-Update/
If the update doesn't help, this is going to be a compatibility problem with the LMS-332 and that particular card. You will need to replace the card or upgrade to a newer unit...but probably can just get used to removing and replacing the card when you turn the unit on.
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.
