First of all, the best thing to do is: browse in Google Chrome, having started your Gmail session and having your location activated.
If you prefer to use another browser: open Google Maps, click the dots in the top right corner of the toolbar, and click "Open in App" (it's installed by default). Now navigate between the two screens (information and map).
This map-guide is specifically designed for use on the road, using a mobile device. If you open it from a computer , we recommend keeping two separate tabs open at all times: one tab with the My Maps map and another with the guide.
You can follow Google's directions to get to a specific point, for example, to start your route and arrive at your preferred starting point. However, if you're trying to get from one point to the next, Google may direct you via a different route than the one recommended, and the accessibility features may be very different.
