Kenwood KDC-MP438U acts as if there is no power to it,dead nothin

I have just installed a KDC-MP438U, all wires are connected correct and have been checked with a meter. red to switch, yellow to battery, black to good ground. The unit acts as if there is no power to it,dead,nothing. I have tested power at the plug as it goes into the unit and power is there, fuse is good and tests positive for power present on both legs. I have 3 of these same units and pluged another into the wired plug for the back of the unit and the second unit will not work either. I tried the reset button and all kinds of buttons on the face, nothing. Any help, ideas?
Thank you.

The speaker wires are very sensitive. You need to make sure that they are not grounding out. Once the unit senses this it will shut off. Pull the plug out of the back and start over.

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 )

I just bought a Kenwood KDC-MP438U I installed all the wires right, power is to the deck because it accepts a cd. the deck face doesn't light up. I called in at Kenwood and they had me test it directly to...


Check your Ground Wire inside the Truck and Check the Illumination Wire. I Think on Kenwood the Illumination Wire goes with the Power Wire. If they still will not work, You might want to get a Wiring Harness from Schoche.com Please Rate My Response! Thanks!
