NAD Upgrade Procedure
To perform the Firmware upgrade, follow the NAD product’s Software Upgrade Procedure and download the latest firmware from the DOWNLOADS/DRIVERS section of each product page.
If the product is not listed under PRODUCTS, search the archived product’s model number using the search option.
If the Firmware update has failed or is not working, you can try performing a factory reset as explained in the FACTORY DEFAULT SETTINGS attachment for the corresponding model. Please be aware, performing a factory reset may result in loss of data such as music service credentials, speaker calibrations, or room correction filters.
If a factory reset does not help, please reach out to your nearest NAD Authorised Dealer/Distributor or Submit a request for further evaluation.
