Yes, the Garmin R10 golf GPS device requires a subscription to access certain features. The device comes with a basic set of features that do not require a subscription, such as displaying distances to the front, middle, and back of the green, as well as hazards and doglegs. However, to access more advanced features such as wind speed and direction, a virtual caddie, and automatic course updates, a subscription is required. The subscription service is called Garmin Golf and requires an annual fee.
