Have had my stereo installed but i have to constantly set the stations etc after i have turned the car on and off. The schematics that i have are in russian and indonesian and can't make out what wires to fix myself
DIKA, first step - check your stereo batt backup wire , you must connect that direct or continues voltage from accu. Don't switch this wire, you can check if your car in off position , this wire must still have voltage +12v - +14v if no voltage check your fuse near batt backup wire. Why that wire must have voltage,that's because the voltage used for backup your stereo memori. OK good Try , Fixya and Don't forget to vote me, thank's
I had the same prob with a kenwood all i had to do was swap the ignition cable with the battery cable ie:default is red(ignition)cable from unit to red cable from car and yellow(battery)cable from unit to yellow cable from car all i did was swap them over ie red from unit to yellow from car and yellow from unit to red from car it keeps its settings now!!!

It sounds like you have a constant 12V power supply wired to the radio instead of a switched 12V. If you've recently installed a new radio, check your wires again. There should be a 12V constant and a 12V switched. The switched 12V will turn the radio off, while the constant 12V is for keeping the clock and radio memory working.
most of the constant power for the wires are use for the memory system of ur stereo eg. for the clock memory, am/fm preset station memory (custom setting of the user). even when u turn off the key, the stereo will not reset to it's default settings.
The yellow wire is the constant 12+V. It has to be hooked up to a constant battery source. If you did not install an aftermarket wiring harness consult http://www.installdr.com/QuickWiring.html to find the constant 12+V wire color code in your dash. If you unhook your battery, you can splice into the cigarette lighter hot wire to keep the constant memory of stations and clock time.
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.
You need to Check the Wiring Harness from the Stereo. There is a Constant Power Memory Wire (Should be Yellow or Orange). This needs to be Connected to the Cigarette Lighter Power Wire for Constant Power Memory. Please Rate My Response! Thanks!
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.
