Supported Maps

To help you have a safe and enjoyable time on the water, Garmin devices only support official maps produced
by Garmin or an approved third party producer.
You can purchase maps from Garmin. If you purchase maps from a seller other than Garmin, investigate the
seller before purchasing. Be extra cautious with online sellers. If you have purchased an unsupported map,
return it to the seller.

Garmin Quickdraw Contours Mapping

WARNING
The Garmin Quickdraw Contours mapping feature allows users to generate maps. Garmin makes no
representations about the accuracy, reliability, completeness or timeliness of the maps generated by third
parties. Any use or reliance on the maps generated by third parties is at your own risk.
The Garmin Quickdraw Contours mapping feature allows you to instantly create maps with contours and depth
labels for any body of water.
When Garmin Quickdraw Contours records data, a colored circle surrounds the vessel icon. This circle
represents the approximate area of the map that is scanned by each pass.
A green circle indicates good depth and GPS position, and a speed under 16 km/h (10 mph). A yellow circle
indicates good depth and GPS position, and a speed between 16 and 32 km/h (10 and 20 mph). A red circle
indicates poor depth or GPS position, and a speed above 32 km/h (20 mph).
You can view Garmin Quickdraw Contours in a combination screen or as a single view on the map.
The amount of saved data depends on the size of your memory card, your sonar source, and the speed of your
boat as you record data. You can record longer when you use a single-beam sonar. It is estimated that you
might be able to record about 1,500 hours of data onto a 2 GB memory card.
When you record data on a memory card in your chartplotter, the new data is added to your existing Garmin
Quickdraw Contours map, and is saved on the memory card. When you insert a new memory card, the existing
data does not transfer onto the new card.
