Problem is the display shows "PROTECT" and nothing works???
The protection function is activated when the speaker wire has a short-circuit or touches the chassis of the vehicle. Wire or insulate the speaker cable properly and press the reset button. (The reset button is that little pinhole button below and to the right of the volume control). If you do this and the "PROTECT" code doesn't disappear, you'll have to consult a service center. Further, if you had this professionally installed, they should be obligated to fix the issue for you (hopefully).

If speaker wires are not shorted you may have a DC power problem. If you hooked up power wrong you will get a "PROTECT" on the display that will not go away.
Try HOLDING the <3> and <6> key down while pressing the reset and continue to hold after releasing the reset button.
You should get a display that says "DC ERR" or "DC OK". If "DC ERR" appears press and hold <1>.
Now Press <2> and you should get a display that says "DC #". # being anything from 0 to 4. if not 0 press and hold <2>.
Turn power off and back on. Hope this helps.

Thank You! I was ready to throw out my Kenwood KDC-MP205 because of this "protect" error. In fact, I had this stereo in my pontoon and replaced it with an expensive marine stereo. The Kenwood has been sitting in the basement the last few months, and I thought it would be great to put it in my '98 Neon. Now, because solution #1 worked, I will be able to use my Kenwood again. Thanks again!
