Sony CDX-FW700 I was given a Sony CDX-FW700 stereo without the user manual. Everything works fine except that I don't know how to set the clock. Any help??

Without a source selector XA-C30, It won't be possible. You can get the installation manual online on the Sony website.

Try to doing a reset to the unit. Detach the front panel and press the RESET button with a pointed object, such as a ball-point pen. Note: This will reset the headunit earsing any stored information.

Press and hold 'SEL' button. (the setup display appears) Press 'SEL' repeatedly until "CLOCK-ADJ" appears. Press 'DSPL' button. (the hour indication flashes) Pess the volume +/- button to set the hour. Press 'DSPL' button to select minutes, use the volume +/- to set minutes. Press 'SEL' button to start the clock. Press and hold 'SEL' ...setup is complete. To display the clock, press DSPL. Press DSPL again to return to the previous display.
