Garmin has created an update for units preloaded with BlueChartr g2 U.S. coastal maps. This update will provide customers with the newest charting additions and Notice to Mariners changes available, including navaids, port plans, depth contours, fishing contours, spot soundings and more.
The update card will also contain a software update for Garmin devices. The software update must be performed on the device before the update map will work. Also please note that the card must remain in the device to view updated maps. The card does not overwrite the unit's internal maps.
