    Hi. Thanks. Yes its sorted. I was installing in on my (17 year old tomorrow) son's 1999 Corsa that we've bought him for his birthday and the original radio had been removed when we bought it. I swapped the yellow and red bullet connecters round in the wiring harness that was with the radio and hey presto. Incidentally, I have just finished checking eerything I think this CD/radio is superb. Thanks again.

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.

Jbl radio A56840 loses station presets and no volume


Toyota vehicles have a fuse in the kick for the amp and sometimes there is located under the hood ... This is the switch turn on for the amp ... And 1 of the fuses is most likely the memory or constant power. B sure to check all fuses ... I do not have AllData pulled up . If the fuses are all good the amp or radio may be bad ... Or both ... Be sure to check all the fuses ... Many times I get clients that say allthe fuses are good and it is still the first thing I check ..Usually is a fuse ..Good Luck

I have a 1998 mitsubishi eclipse gst. had the battery chanced and now the radio won't work. have code for radio but don't know how to enter it into radio.don't know what buttons to push. owned car about 7...


The 1,2,3,4 preset buttons on your radio toggle up only through the digits 0-9. The 1 preset button is the first digit holder, and so on for the 4 digit code. If you go too far just keep pressing the button, and it will go back to 0, and you can get back to the right number. If your unlock code has a 0 in it you have to press the button once to get to 0. It starts with a dash (-). This doesn't count as the 0. For instance if your unlock code is 0873, you will press preset 1 once, preset 2 9x, preset 3 8x, and preset 4 4x. Once you have the correct number in the display press the "CD" button, and it will unlock your radio. If you didn't do it right, it will display "ERR1" before going back to the "CODE" display. Don't mess up more than twice. After the third failed try things get a lot more complicated. Good Luck Tim

Cannot maintain preset settings.


Do you have a fresh battery in the unit? Make sure your 'reset' button inside the battery case isn't 'stuck' on (push a little pencil in there).
Fresh battery, then do a reset inside the case, do a reset to factory settings, then try normal on and off with the switch and see if that fixes it or not.

Unlock procedure for vw/audi


audi gamma cc type


1e2fb0f.jpg The following is the procedure to re-activate the radio if the display shows "SAFE". It is important that the procedure be followed in the correct order.

  1. Turn on radio. The radio display shows "SAFE".
  2. Press the FM1 and AM buttons simultaneously and hold until "1000" shows on the display. Release the buttons. Do NOT press these buttons again, otherwise the radio will consider "1000" to be the code.
  3. Use Preset buttons 1 ... 4 to enter the four-digit code number from your radio card. Preset button 1 corresponds to the first digit, Preset button 2 corresponds to the second digit, etc. Each press of the button increments the number by 1.
  4. Once the code shown on the display is correct, press the FM1 and AM buttons simultaneously and hold until the word "SAFE" appears in the display, then release the buttons.
  5. The radio should unlock and be usable shortly afterwards.
  6. If an incorrect code is entered, the word "SAFE" appears, first flashing and then continuously. You can repeat the above steps to unlock the radio once more, the number of attempts will be shown in the display. If an incorrect code is entered again, you radio will be locked for about one hour. After one hour - the radio must stay on and the key must remain in the ignition lock - if the display goes out, the you can repeat the above procedure to unlock again. The cycle - two attempts, one hour lock-up - still applies.
  7. If you lose your radio code, contact your Audi dealer.

Every time i turn my vehicle off i loose all my presets on my stereo


if this is not the original radio, then the wiring is wrong on your replacement. With the replacement radio, theres a wire that needs to be connected to Battery (+). this keeps presets and clock from losing memory

2. Press "Time Set" button to enter set mode. Note it says "Preset" below this button, because it is used to set both time set and presets.
3. Select the preset number you want, using the "Preset" buttons.
4. Press "Time Set" button again to exit set mode.
5. Repeat the above process for each preset.

Jvc car cd/radio


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.
