Click Here For Sony Owners Manuals (sony.com)
Sony has some of its home and car audio/video owner’s manuals available for download in pdf format. The link above will take you to a page where you can search by model number. You will want to enter the entire model number. For example, when I entered xr-ca350 no results were returned, but when I entered xr-ca350x, 3 results were returned.
