Subscription pro-rata

I signed up for the navdata only (paid yearly). Is there any way to upgrade to the ultimate package without having to re-pay the full price? I’d like to only pay the difference between what I’ve already paid and the full subscription.




In order to upgrade your existing subscription to Navigraph Unlimited including charts, please visit our website and log in to your account, then click on “Your Subscription” from the menu bar to your left.

From there you can manage your subscription, including upgrading to the Navigraph Unlimited subscription.

If you upgrade to the Unlimited yearly plan, you will get credited for the unused time of your current subscription in form of a discounted price.
