    Hello.

    I bought the emulator as in the subject.
    The problem is that every time after turning off the car begins to play from the beginning.

    It is connected using a standard allegro adapter. The radio is a bare cassette chorus. At the end I have a pendrive.

    I bet that the problem lies somewhere on the side of a lack of constant power supply.

    The player remembers radio stations so here is ok
    One thing that comes to my mind is that the radio without the key in the ignition position will not start.

    Any suggestions?
    I have a meter, I also know the basics of electrics.


    Best regards and thank you in advance for your help.


    Ps. The ground cable of the changer is screwed to the radio.

    Uses all cables from the emulator? Show connection diagram.

    Such a photo won't tell you anything.

    Check if you have pin 16 connected and if there is + 12V - the radio must be connected, the ignition switched off.

    No ignition, no electricity. 12.5V appears with ignition

    It remains to disconnect this cable from the radio and connect it directly to 12V.

    I hurried up a bit and made a bypass from the lower ankle (red-black wire) to the one you marked. This solved two problems:

    The changer remembers the songs
    The radio works without ignition.

    Is this solution ok?

    Probably not. This is not a radio socket and maybe it will work, but I don't have a radio scheme to give 100% certainty.

    Certainly it will sound like you forget to turn off the radio at night.
    This is why the radio works only "behind the ignition".

    I've always wanted to have no ignition.
    For example, in the Skoda company I have a radio without a key that plays for an hour then turns off. The cable from which I led the current to No. 16 is the cable with the largest cross-section and as the only one has voltage without a key.


    Maybe different ... How to connect it wisely ...

    In that case you should have + 12V in the bottom (from the picture) ISO plug, pin 4.

    So I connected.
    But I noticed that after this procedure the backlight of the light switch is on all the time.

    It depends on the bank because after disconnecting the radio goes out.

    Maybe you made a mistake with pin 6, besides you need to unplug the current cable, you can not bridge these cables with the installation of the car.

    The cable from pin 4 of the lower cube, I put in place of pin 16th.
    Except that the light switch does not go out, everything works as it should.

    Can it connect a rectifier diode?
    I don't know, I think up what could be wrong.

    Ps. After all, I will not pull the battery cord now.
  • Admin group computers
    You can give a diode, at least partially protecting the system.

    The question is where does this glowing light switch come from?

    Added after 14 [hours] 49 [minutes]:

    Today I noticed that how could I not give this current, the key from the lights is illuminated. I stupid quite ...

    Hello.

    Thanks mate DriverMSG the problem was solved and the changer works and also remembers stations without backlighting the light switch.

    For posterity ....

    In general, the whole "factory improvement" was that:

    - cut the wire from pin No. 16
    - we make a "bypass" (we plug in wire No. 4 of the lower cube - solid 12v) to wire No. 16.
    - we insert two rectifier diodes (1A is enough) according to the attached picture.

    All in all, the main reason for the proper operation of the changer, but the lighting switch was lit, was that the current, apart from the changer, was also going to the radio.
    After blocking the power diode, everything works as it should.
