Question about Car Speakers & Subwoofers

2 Answers

I have a peugeot 207cc and I had a peugeot cd changer(it is actually a Blaupunkt)installed. My problem is that the cd changer always starts from cd 1 track 1 on initial startup and does not remember which cd/track it was playing when the ignition was last switched off.

    I tend to agree that the unit does not have a 'always on' supply. How would I know which Pin I should power with the battery power on the cd changer?

    My peugeot 207cc has got a standard Peugeot cd/radio fitted which is made by Siemens (according to the label fitted on the unit) The CD changer is a BLAUPUNKT IDC-A04 and is fitted to the cd/radio by a special harness which fits in the main plug of the cd/radio. Maybe this can help you be more specific. Thanks for your help.

    Some further information - I have just checked the voltages on the harness leading to the cd changer - There is 12 V on Pin 1 (and it is a yellow wire) with the car and stereo switched OFF.

    The problem may be because the contsant 12V and the memory
    12v need to be changed over, the wires should be the red and yellow, if
    i remember rightly.



    if you look at the plug face on, the yellow wire is top second on the right, and the red is second line down far right.



    Please rate the solution.



    Thanks

Hi,

I would venture that the main B+ wire of the Blaupunkt CD Changer is not connected to an always on B+12 such as the positive terminal of the battery. This wire is responsible for memory/location/track last play retention. The other B+ of the CD Changer is the remote trigger on which is fed by and from the head unit. This in effect makes the unit operate with two (2) B+,an always on and a triggered on.

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.

    Of course in some instances, it may be the head unit that is missing the always on B+. This could be confirmed if the radio (FM/AM) radio presets revert to default on powerup of the headunit.

    Hi again,

    You would need a DVM (voltmeter) and with the power on to the unit, test which of the wires carry +12, chances are it would only be two. If the system follow ISO standard, then yellow would be for the always on B+ while red would be the trigger on B+. In some installations, the red could be connected to the blue or blue/white of the head unit.

    If for some reason a different wiring color scheme is used, I guess given a choice of two wires (both of which technically receives 12V), you can try a little experimentation with no possibility of any untoward incident. If the first guess/choice does not work, then it would be the other. Sorry for the guess work but not knowing the exact model of the CD Changer kinda limit information.

    Again, good luck.

    ohhh, your post indicates that there is an always on B+12 on the yellow wire which should make the unit retain memory of last setting. Since this is contrary to what is happening, then it can be safely assumed that the CD Changer has a slight electronic fault which prevents memory retention.

    This fault could be a simple case of internal loose connection or cold solder or even a corroded/looses terminal connector outside. Other than confirm that the harness is snugly fitted to the CD changer through its connector, am afraid that further diagnosis would require opening the unit up.

Cd changer is mainly a mechanical unit, most common problems are caused by gears and dirty lens.
Try disconnecting the cd changer power cable and connecting it back, if it reset the changer it will restart working normally, if not you have to replace or take out for repair the cd changer.

Have a Blaupunkt AM FM Radio/In-Dash Ch Cgnager (6 stacker) in a 2003 Holden Commodore. After ejecting the 6th one of the CD's succesfully, get "CD Error mech" message and it will not eject the...


We eventually tried loading another CD to fill the one vacant spot we knew was in the changer even though we'd tried that before without success. This time it seems that we fluked it just as it was trying to eject CD 1 again and - somehow - the CD we were tryng to insert must have lifted the rim of the one that was stuck and it suddenly ejected. The remaining 4 CD's that were inside the changer but not even recognised, then started re-loading so it appears that they were all jammed up together. Once they'd reloaded we were able to eject them all successfully then reload.
We're not sure but think that it may have happened when the eject button was originally pressed once to eject CD 6 then, in error, held down for a 'eject all' procedure and the changer has become confused with both instructions.
