BlueChart® g3+LakeVü g3 Built-in

Bring new levels of detail to your Garmin chartplotter with this preprogrammed map update card that gives you detailed electronic nautical charts and lake maps. This package contains map data and a software update for your device. You must perform the software update on your device before this map will work. The card will need to remain in the device to view updated maps, if there is insufficient memory to update the built-in map. *Recycled microSD™ cards may be used to program map data. Engineering enhancements are ongoing and may not be reflected in the pictures, videos and specifications.
