Once Nikon receives your product, we will inspect your product and log it into our system within 1-5 business days. If there is a fee for your upgrade we will email you a link to our secure approval website to enter your credit card information for payment. Once you approve the payment, our service technicians will perform the upgrade within 3 business days. Once the upgrade is completed, you will receive an email with a ground shipping tracking number. Depending on where you live, delivery could take up to 5 business days.
