Upgrade with the Best Garmin Maps on the Water

A single microSD™ card slot provides expandable memory for accessory map purchases such as LakeVü™ HD, LakeVü HD Ultra or BlueChart® g2 or BlueChart g2 Vision. LakeVü HD Ultra and BlueChart g2 Vision provide exclusive Garmin Auto Guidance that directs you right to your hot spots by instantly creating an on-screen path based on your boat’s specifications that you can follow to avoid shallow water and other charted obstructions.

Enhanced Auto Guidance

Just enter the location where you want to go and patented Garmin Auto Guidance technology instantly searches through relevant charts to create a safe virtual pathway on the display that helps you avoid low bridges, shallow water and other charted obstructions en route.

Better still, with enhanced Version 2.0, you now have access to even more features and capabilities. You’re able to adjust the calculated Auto Guidance pathway by inserting “via” points at interim stops or landmarks along your desired route. You can easily review hazard points along your calculated path. And you can even engage your compatible Garmin autopilot to follow the Auto Guidance route, automatically. Other 2.0 enhancements give you the ability to calculate arrival times at any point on your route (great for timing arrivals to correspond with bridge openings and other time-critical events). Better still, you can now save your plotted Auto Guidance paths for future navigation by backing them up on an SD™ card with your BlueChart® g2 Vision® or Lake Vü™ HD Ultra cartography².

GPX Waypoints Transfer

If you have waypoints, tracks or frequently used routes stored on another manufacturer’s GPS product – or on a Garmin handheld device –  now it’s easier than ever to transfer those items to your new Garmin chartplotter, via industry-standard GPX software formatting. GPX is an open standard format for GPS data exchange across platforms and applications. With this easy-to-use interface technology, Garmin has taken “no waypoint left behind” to a whole new level of trade-up convenience.
