To zoom in or out on the chart, you can use your thumb and index finger. By pinching your fingers together, you zoom out, and by spreading them apart, you zoom in. If you find this difficult, follow the steps below instead.

1. Go to the “Plan” tab if you are planning a route, or go to “Navigate” if you are on the water and traveling with or without a route.

2. In the lower right corner, click (+) to zoom in and (-) to zoom out.

3. The chart will adjust so that your current location is in the center of the screen.
