    installing audio in for MP3 player on stock radio. searched for an hour

    My first post. I searched for an hour but didnt' find and answer.

    There was a post similar to mine but not exact. here's my situation. I have a 2000 Suzuki Esteem 4 door with a factory stereo which has controls for an optional, external cd changer. I'd like to install a female audio jack anywhere in the car and have it input somewhere in the radio.

    I realize that I may need to make a dummy plug so the radio thinks there is a changer connected.

    assuming I am correct about the dummy plug (with the audio input) am I on the right path?

    follow-up question: where can I find FREE wiring diagrams for this connection (cd changer) and for the radio. If I have a chance I will edit with exact brand and part number of radio. I've looked for while and cannot find it online.

    Thank you all in advance.

    Erik

    im not sure what the stock HU has as far as i/o ports on the back but i just grabbed a aux-in rca adapter for my alpine HU that plugs into the CD changer input was like $20... in my last car i ported the aux line to a blank panel in my dash by drilling a hole in it and mounting a female 3.5mm input... worked pretty nice

    there is a hard-mod way if other not works: wire directly to the mixer IC, instead of radio or CD sound... just open it, and note the IC-s on the PCB (this might be a TDAxxx labeled flat one, not the heatsinked on the border), than we will help you with other steps...

    / by this way you will need a not too big soldering iron too... /

    I looked and it only has a 13 pin din. I found a mod that includes a switch and an audio input but I think I have to have a ch changer installed first.

    usually its a SOIC-type IC, like this:



    for example the TDA7348
