MAPPING PROBLEMS

Here are some suggestions that could solve the problem and prevent you from having to be without your unit!

AccuracyLowrance Electronics obtains its mapping data from government agencies.  Mapping is not an exact science.  A unit's GPS position (Latitude/Longitude) can be extremely accurate, but the location of a cartographic item such as a street, highway, or point-of-interest may be slightly inaccurate. In most cases, we have found the mapping detail in our products to be very accurate.

We encourage the reporting of inaccuracies or omissions so that we can consider them for future revisions.  Please consider that our products are designed to be aids to navigation and not the sole means of navigation.  A prudent navigator will also have several items necessary for safe navigation.

ExpectationsIt is almost impossible for any mapping agency to keep up with the changes and additions that occur.  Roads or highways that you know have been around for a some time, may still not be a part of the database provided with our products.  Again, we encourage the reporting of these items so that they can be considered for future revisions. 

* Cards are not Read by the UnitBefore purchasing a pre-loaded mapping card for a unit, go to our Mapping Index at this link:  

http://www.lowrance.com/Products/Mapping/

 Click on the type of card you are interested in and look at the list of units that are compatible with that card.

-When zooming in to see more detail, be sure the cursor is located within the area covered by the mapping card.

-In the menu, select Map Data.  If you have a Navionics card, make sure that Navionics is selected under Map Choice.  For all other cards, select Lowrance.

-In the menu, select Categories Drawn.  Make sure all the categories you want to see have a check mark beside them.

-If the card is not recognized by the unit, make sure the card contacts and corresponding unit pins are clean and free of obstructions.  Verify that the card is securely seated in the card port.

-Try resetting the unit as described below.

- If it is a card for a MapCreate map or saved GPS data, it may need to be formatted.  Do not format pre-loaded cards such as Insight, Nautic-Path, Fishing Hot Spots Pro, Lake Master Pro, Freedom Maps, or Navionics.  The information will be deleted from the card.

Please be aware that Lowrance GPS products will only read cards that are FAT formatted.  MMC cards formatted using FAT 32 or NTFS will not work with our products.

* Current Position not on the ScreenFirst, make sure the unit is locked onto the satellites and shows a fix on the satellite status screen.  Then check for cross-hairs on the screen (or for an automotive unit, a red box with an X).  If this is on the screen, it means that you had pressed one of the arrow buttons.  When that is done, the unit thinks that you want to scroll to a location on the screen or zoom in or out to see more detail.  Simply press the EXIT button to clear the cross-hairs and your current position will now be shown in the middle of the display. 

For an automotive unit, press the red box with the X in it to return to your current position.

* Update the Software: Make sure your unit has the latest software version.  Click here to go to the Software Update page on Lowrance.com.  The updates are free.

* Reset the UnitSometimes resetting your unit can solve unusual issues. Click here to access a list of reset procedures for Lowrance products.  Locate the one that applies to the model you own.  Try a Soft Reset first, this will return your settings to factory defaults.

If you decide to try a Hard Reset, save any important stored data to an MMC or SD card or write the information down.  The data will be deleted during this process.
