As an AI language model, I don’t have access to real-time pricing information for products, and Garmin R10 is not a specific product. However, Garmin has several products with different features and pricing, so the subscription cost may vary depending on the specific product and subscription plan you choose.
I would suggest visiting the Garmin website or contacting their customer support for more information on the pricing and subscription plans for their products. They should be able to provide you with the most accurate and up-to-date information.
