    Post Aiwa CDC-MP3: Aux Input

    I am looking for an auxillary input adapter for the Aiwa CDC-MP3 (it has cd changer controls built in). I know it has Aux in on the front, but I'd rather not have a cord running into the front of the radio.

    Anyone have any idea if such an item exists?

    If it doesn't, anyone know how I would begin to hack one together?

    Thanks,
    TP

    If you're brave, you could open the thing up and wire up a 1/8" jack on the back, and solder it to the connections on the front of the player on the inside...

    I think I may try that. However, it won't be that simple because the face is detachable and all of the connections on it (including the front aux in) get routed through a central connection to the main unit. I'll have to figure out where the aux in signal ends up.

    Another option is to come in through the cd changer input. I would prefer this since there would be no modifications to make. Any ideas how to get started on finding what connections do what? Links anyone? (I've searched the board extensively on this and have found very little concrete info.)

    In general: Is there a certain connection that has to be grounded in order for the head unit to think that there is a changer attached? Is there anyway to find out this info?

    I suspect there is not after reading all the posts I could find on this board so I am going to look into hacking into the front aux in.

    hey, i have the same player. if you look at the terminals with "aiwa" right side up the ground is the back right. the left is the top right and the right is the top second most right.
    I may be able to help you further but don't want to take it apart tonight

    And I think there has to be some something to trigger the cd changer because it skips the "cd changer mode" when flipping through the functions.

    As for the cd changer input...i'm clueless. Maybe if the aux in went to same place you could do a continuity test between the two?

    I was thinking that the Aux-In on the front was not part of the Face, since it seems like the face is not quite 1/2 inch thick, but i guess I could be wrong. I thought this had been done by someone on the board already.

    Yeah, i got an aiwa unit, and i posted a picture of the circuit board here, trying to figure out how to solder the connections for aux in. It would be really nice to eliminate that cord in the front if someone can figure out how.. I never did.

    I was able to open my Jensen cd player and tapped the lines fron the CD player part, this works great although I need to have a blank cd playing at the same time.

    I'm not sure if this helps but on the Blaupunkt in my car, it had an aux input that wasn't listed anywhere on the specs. There where a whole bunch of pins that weren't being used by anything so I tested them out and found that 2 were left and right inputs. I split the audio out from my comp to RCA left and right and then cut off the plugs and attached the wire directly to the pins using a male to female serial converter that just happend to fit perfectly. Anyway, maybe your reciever has some sort of aux input like that. Good luck
