If you remove your head unit, you will need to switch the red and yellow wires around! different cars have different modules. yellow will then be constant 12v source! let me know how u get on, i have the same unit!

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.

Display for radio stuck in '7 SAFE' mode


This sounds like a Phillips Car Stereo:

To get the code in:
1. Turn the stereo off.
2. Turn off the ignition
3. Turn the ignition back on (dash warning lights on)
4. Hold and keep down the AS button on the stereo.
5. Turn the stereo on.
6. Release the AS button after 4 dashes appear on the display
7. Now enter code (if code = 7009. Press preset button 1 seven times, button
2 once
3 once
4 nine times
If you go past you can go round again by pressing the
preset button repeatedly
8. Once all 4 numbers are correct hold down AS again until you hear a beep (2 - 5 seconds)
9. The stereo after beeping will scan to program channels
You have 10 attempts to get the code in. However some models will not give you the number of attempts remaining!

Time delays work as follows:

Attempt 1. 10 seconds
Attemp 2. 30 seconds.
Attempt 3. 10 minutes.
Attempt 4. 20 minutes
Attempt 5. 40 minutes
Attempt 6. 80 minutes
Attempt 7 160 minutes
Attempt 8 320 minutes
Attempt 9. 640 minutes (yes that is 10 hours 40 minutes!!)

Vitally important thing to remember, the countdown timer works only when the radio is switched on. ANY interruption in the power will reset the timer!

So, be prepared for a VERY long wait to be able to enter the code!
Oh, and if it has reached 10 attempts, then it needs a dealer unlock.

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.

My subwoofer drained the battery to the car over night


I am not sure how you have it hooked up, but the amp should be connected with heavy gauge wire to a relay that goes straight to the battery for the best current flow. The coil of the relay can be connected to the power output wire of the stereo (usually blue) or to a switched circuit. When the ignition is switched on or the stereo is turned on (depending on which you have it connected to) the power to the relay coil will connect the power from the battery to the amp. When you turn off the stereo or ignition, the power to the relay coil goes off and the spring breaks the circuit at the contactor. You can buy a relay at any auto parts place. Make sure you ground the amp near where the stereo is grounded or you will get a whine in the stereo from a "ground loop". Please don't forget to rate this solution.

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.
