How do you switch to radio from CD on kenwood kdc?

To switch from CD to radio on a Kenwood KDC stereo, press the "SRC" (Source) button repeatedly until you see “Tuner” or “Radio” displayed on the screen. This will toggle the unit's source selection. If your model has a dedicated "Radio" button, you can also press that directly. Ensure the CD is ejected if you want to completely stop playing it.
