Anytime there is a short circuit or your battery down low enough you will recieve this signal. If you press the little "reset button" using a small pin or screwdriver your unit should reboot without the "PROTECT" signal. If seeing this "PROTECT" sign is a result of jumping your car, this will fix it. If the signal persists, then there is still a short circuit and you need to check your connection with the battery. Most likely it is touching the chasis or some othere metal.

Disconnect the power, check your speaker wire connections behind the stereo and at the speakers. Reconnect the power and test.

I have a kenwood KDC-MP438U stereo. Ipod error.


Hi If anything the stereo was probably designed and tested using a certain version of the Iphones software, now that version 4 has been released the way the IPhone communicates may have changed.

As a result the stereo is no longer able to talk to the phone and vice versa. your probably best off contacting Kenwood direct to see if they are aware of this problem and if there is anything that can be done about it.

On my kenwood kdc mp438u i tried everything it said to do but it keep saying protect


Could be a short circuit on your speaker output, try disconnecting all 4 speaker wires and then power up. Otherwise its the audio amplifier circuit that needs to be replaced ( audio IC )

Solution is simple and no code is needed. Make sure all wirw are secures and not opening spliced. Ones verifying, make sure radio is turned off and reset the protect button.

The Protect Button is pin hole size and is located right above the headphone jack. Hence all shpuld be good from there on.

Reset

Security Code for Protect mode


Turn on the car so the radio is flashing "Protect." Look on the front / removable face of the stereo. On it you will find a small round hole - that's a reset button. Find a small paper clip, unfold the clip and stick it gently into the hole. The "Protect" will stop flashing, and Kenwood will be displayed. Unfortunately all your settings/presets will be gone, but at least the stereo is working again!
