There is a YELLOW wire that needs to be connected to a constant + 12 volt source when the vehicle is off.

Best of Luck.

Re: Kenwood KDC 237

You need a constant 12v current to the radio unit. Unfortunately, sometimes the yellow wire does not carry the constant current even if it should.

You need to take the unit out and, preferably, use a multimeter to confirm the current is absent. In my case it was, so I disconnected the snap connection on the yellow wire and connected it to the spare red socket which is easily identified, and was the one carrying the constant current.

However, it means that you need to make sure you switch the unit off before you leave the vehicle since the radio will eventually drain the battery if left on over a prolonged time. In my case I always remove the front anyway, so that solves the problem.

NO memory in kenwood kdc-mp205

check your wiring in your vehicle to make sure that the yellow wire from the stereo gets "constant" power. It it what keeps your stereo's memory, and powers the audio amp in the stereo. If this wire is loosing power when you shut the key off in your car, you will loose all of your settings...bass, treble, tuner, clock, and also where you left off on your CD.
