I have a KDC W311. Everytime I switch off the car engine, all the settings are reverted back to original. I lose all the preset radio stations and have to set it up for audio again. I cannot believe that it does not save all of this data. It's like the 'reset' button is pressed everytime. How do I get it to save all my presets? Thanks

if the radio alarm is still showing the nonexistent 98.5, you would need to reset the radio alarm. Press and hold button 1 (top left hand side) until the display starts blinking. Then press the preset button for 98.1. It should then display 98.1 on your radio alarm. good luck this is the most difficult set of instructions I've seen yet

SOURCE: keep losing radio presets

Hi,

Most current car head units requires two (2) kinds of B + supply; the yellow should be connected to an always on/constant B+12 such as the positive terminal of the battery. This is responsible for the memory and setting/configurations not to be erased when powered off. The red wire is connected to a switchable B+12 such as the ACC terminal of the IGN switch making the radio work only when the key is turned to ACC. Of course,the black is ocnnected to the chassis/ground.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

The radio was improperly installed; there are two 12V leads, one services the radio when on, the other, only the circuitry for the clock and presets.
Eventually, this shouldn't be needed if the manufacturers ever think about using a little bit of flash memory for the presets and a coin cell for the clock.

You didn't give any model number so researching the manual is impossible.
If you can find the model number, look for a user's (or installation) guide on line to find the wiring info.

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.
