The vehicle has a constant power source that needs to be connected to the radio. If a fuse has disconected the circuit then you will lose your "memory" for your radio. Look in the owners manual for the fuse box locations. Use a light to find the fuse that has disconnected the circuit.

Do you connect memory and power to the ignition terminal wire


The yellow (memory) wire needs to go to a constant power source in order to retain the memory, the red wire goes to ignition. You can connect them both up to the ignition, but you will lose preset and clock memory every time you turn the key off.

Each time i turn the ignition off the cd receiver loses all the pre set channels and you have to re enter the stations each time


It sounds like you need to make sure the yellow wire is going to a constant power source. That is a source that is still hot with the key off.

It sounds like the 12v battery lead has an issue and thats why they tied them in together. Once you resolve that issue and re-wire properly you should be set.

Stereo does not store adjusted audio settings and restarts after being turned off


Check to make sure the yellow from the stereo harness is connected to constant battery, connected to the battery, when the ignition switch is off, the yellow wire still has power. The yellow wire is for the memory for the stereo settings and radio station presets.

Stereo problem


Sounds like the constant 12v supply is missing - blown fuse? or the wires are reversed. The constant is for memory functions, key-accessory for everything else.

Stereo stations wont stay set


If you have a yellow wire that is the memery wire. It needs to be hooked to a constant hot. If you do not have one you need to get a new plug for the back.

When my daughter turns her car audio off, we loose preset stations.


Two questions to narrow this down - one, is it an aftermarket stereo, or a factory one? Two, with the key out of the car, can the stereo be turned on?

If it's aftermarket and it powers on when the key is off, then it's likely two wires are reversed in the harness behind the deck - the constant 12v wire and the switched 12v wire. The constant one is the yellow one, which always supplies power to the deck, keeping power there for the preset memory and the tone settings. The ignition-switched one is so that when the key is turned off, the stereo shuts off (this is the red wire on the harness). If these were reversed, the stereo would always be able to be turned on, and power to the memory settings would be lost when the key is turned off.

Everytime i turn my car off and take the key out of the ignition all my stereo presets reset. all connections made are correct, however there is one wire which is left over. it is orange with white stripes...


Most stereos have two power connections. One is "constant" (aka always connected to +12V) and the other is switched on/off by the ignition. They may go be various names. The idea is that the constant +12V keeps the stereo from losing all of the settings while the switched power turns the stereo off when the key is not on "start" or "accessory". It sounds like the both connections may be made to the switched power on your car, causing it to go completely powerless when your car is off.

Are the presets reset after you turn the car off or only after you turn your car back on? If they only reset after turning the car back on, it's possible the battery and/or electrical system is having trouble keeping the system voltage up while the starter is trying to turn the engine.

The illumination signal is usually used to let the stereo know when you've turned your headlights on, so it can dim the display automatically. Should be completely separate from your issue.
