![]() Select and wait for it to copy the maps (takes a minute or so). Put the SD card in your computer’s SD card slot.When complete, you can remove the SD card and turn the chartplotter off. Open Garmin HomePort on the computer and choose the correct chart.You have to use the card every time - there is no way to copy the charts to the hard drive and have HomePort read them from there. What is listed as “Global Map” is very low res don’t use it. If there is more than one other chart (for some reason there are two others on mine), try each to see which is the higher resolution. The higher resolution will NOT show up until the scale is less than 10 miles (the scale is shown in the bottom right corner) - use your mouse wheel to change the scale if necessary. This is how I create a route - the process is not exactly intuitive and I never found a good how-to. I am sure that there are other ways to create a route. Click on the hand symbol in the toolbar (Pan) that’s just above the red arrow in the screenshot above.I find it extremely helpful to have a mouse with a scroll wheel. Then use a combination of your mouse wheel to zoom in and out and click and drag to reposition the map so that both the start and end points of your trip are on the screen. ![]() Click on the three connected green boxes (New Route) your mouse pointer will turn into a pencil.It does not matter if you can see the exact detail of the start and end point now. Now click near your starting point (it doesn’t have to be exact - just get close-ish), then click near your destination (again, just get near). Now zoom in on your starting point, using the mouse wheel and dragging the map (using Pan) as needed.You’ll have a straight pink line going from your approximate start to finish. Click on “Move Point” (three to the right of New Route). Go back to the start area, and now click on “Insert” (one to the left of Move). Click on the pink line, then click where the first waypoint (after the starting point) should be.Click on where you put your start point and drag it to the actual starting point, then release the mouse. You can click on Active Captain notes to read local knowledge or reviews of anchorages and marinas. If you need to move a waypoint, use Move Point and drag it to the correct position. You’ll notice that your route has a “name” that is just waypoint numbers, such as 701-710.As you hold your mouse over the route, a little box will appear with the route distance and a time estimate (this is only as accurate as your boat details that are entered in Utilities > Manage Boat Profiles in HomePort).Double and triple-check your route for hazards while zoomed in.There’s also an erase feature (looks like an eraser in the toolbar) - click it, then click on the waypoint you want to erase. This is absolutely horrible when you are trying to find the correct route on the chartplotter! In the route list on the left side of the screen, right-click on the route and then click on rename. Give your route a more descriptive name, keeping in mind how many characters your chartplotter will show (anything more than that will just be chopped off).
