    Hi all,

    I recently bought a second hand CD43 to fit to my E36, and stumbled upon problems during installation.

    I disconnected the battery, replaced the old unit for the CD43 and re-connected the battery, at which point I noticed the little red light flashing on the unit. At the time I didn't have any instructions to hand, and was trying to figure out how to enter the security code. As I didn't immediately figure out how to do so, I fed the unit a CD, to make sure it was receiving power. At this point it ate my CD and now refuses to give it back.

    In fact, it now refuses to do anything at all, so I tried re-installing it, and now that I know how to set up the unit it seems to be completely unresponsive (no flashing red light, no signs of life at all.) Does anyone have any ideas of what to do? I'm pretty stumped myself, so any help would be appreciated.

    The red piece? Yes, it does. Could it simply be a case that the fuse has blown?

    What should the rating of the fuse in the back be? The one in my unit is 10 amps..

    The fuse in the back looks fine to me, and also the two fuses relevant to the radio under the bonnet seem fine too

    Mine did that when I was installing and the battery power dropped. This unit has a voltage threshold. I'm adding the following to be passed along to all our compatriots. I noticed a dearth of info on installing in the older E30s.


    INSTRUCTIONS for wiring the CD43 to existing E30 circuitry and hardware seamlessly.

    It will leave you with the same or slightly better sound quality as the original radio.

    There are only four wires coming from the existing original E30 radio concerning sound. These are the ones going to the amp.

    BLUE- - Right Channel
    YELLOW - - Left Channel
    BROWN/BLACK - - Ground -- Splits to 2 wires from one coming out of old unit
    WHITE - - Amp On Switching -- Splits to 2 wires from one coming out of old unit

    SPEAKER LEADS pigtail and BLUE wire from POWER pigtail

    The RIGHT FRONT + from the adapter pigtail attaches to BLUE
    The LEFT FRONT + from the adapter pigtail attaches to YELLOW
    The RIGHT FRONT – and LEFT FRONT -- from the adapter pigtail get tied together and capped. They attach to nothing.
    One of the WHITE wires from the original radio turns on the antenna and the other turns on the amp. The BLUE (ANTENNA) lead from the POWER LEADS pigtail attaches to these two.
    The BROWN/BLACKS that came from the old radio get tied together and capped. They attach to nothing.

    POWER LEADS pigtail

    Connect the YELLOW (MEMORY) pigtail lead to constant power.
    Connect the RED (POWER) pigtail lead to switched power. (VIOLET/GREY)
    Connect the ORANGE (LIGHTING) pigtail lead to a line that comes hot only with the light switch.
    Connect the BLACK (GROUND) to a body ground of your own making. I highly recommend this in order to avoid potential problems with specific equipment grounds.
    The BLUE (ANTENNA) has previously been attached.
    This hookup will utilize all existing equipment including the fader. The fader on the radio menu will not be operative, but all other menu options will. The fader option is switched to the hardware fader above the radio.
