Sorry, during the website update, the XDJ-RX firmware and driver update page was not shown for a short while.
Actually, the XDJ-RX support page was removed from the page below because it became a discontinued model.
It has been moved to the PRODUCT SUPPORT ARCHIVE page below.
If you scroll down to select XDJ-RX in the above page, you can find the Support page and see the firmware and driver update information as well as the manuals.
Thank you very much for your kind understanding.
CRM, Pioneer DJ
