FAQ - Frequently Asked Questions

I don't want to pay, but still appreciate the service - what can I do?
Leave a review - that's the (second) best way to show appreciation and provide support for the whole system. Thank you. Opening the app page from Garmin on your phone / ConnectIQ app will allow you to review.

Can you add specific rain radar images for where I live?
Possibly... where do you live?
Not all countries publish public or accessible rain radar information, but more do each year. Get in touch, especially if you know data is available, either publically or under a developer license.
