Im trying to firgure out what the memory wire is. Everytime i cut my car off i have to reset all my stations and i have to start my cd all over again.

Red is Positve = +
Black is negative = -
Yellow is the backup - If the backup is not connected, the radio station will lost it memory if ignition is turned off, and cd will start from no 1 and won't continue when it was last played. - Yellow must be connected to the Battery or positve wire which does not switch off if the inition is off

The yellow wire is your memory wire and needs to go to a source that is still hot (still has power) when the key is off.

You are losing the permenant 12VDC on the Radio. This is the thick yellow wire from the radio loom, it has to be connected all the time to 12VDC.
Cheers

more than likey u dont have the memory wire wired correctly...chk the memory wire it should b an orange wire make sur eit is hookd to a continus power supply...if not then everytime u turn off the car it will reset..i have my memory wire wired with my red power wire

you have the constant power wire and switched wire backwards.
Switch the red and yellow wires around.

Thanks for using FixYa - A FixYa rating is appreciated!!

you need to have whoever installed the unit connect the YELLOW (memory) wire on the back to a constant 12 volt power source. It is hooked up right now to only have power when the key is on. this is why when you turn off the key, you loose memory.

what kind of car is this in... I can tell you what wire goes to what color if you cant figure it out.

Hi,

The yellow wire must be directly connected to an always ON B+12 such as the + terminal of the battery. This wire is responsible for providing power to the memory.

Hope that 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.

run the yellow wire to the battery as its the memory wire and that will work if it is installed correctly and still does the same it can be the battery even if the battery still works.
