How to make an audio input on your car radio

Here I'm gonna show you how to make an input to your car radio (head unit) for connecting iPod, MP3 player, DVD, laptop, CD player AKA discman etc.

First you need to find the tuner. In my example, it's standing vertically to the main board, located in a shielded case. It's connected with main board through soldered pins. I found pins that are audio output from tuner (in my unit there's a description of each pin). I cut lines that are connecting this output with preamplifier input, with scalpel. Then I mounted a double KIP switch and a 3.5mm female connector for input. I connect input, tuner and preamp input on the switch, so I can switch between tuner and audio input for listening.

I know you can use FM transmitter or audio tape with 3.5mm male connector, but most of them produce low quality sound. This is a direct input into your unit with crystal clean sound and the best quality your unit or source can deliver.

You just need to put the switch to input, choose the tuner source on your head unit and connect your source. You will hear the sound from your iPod, MP3 player or whatever you connect.

The only "bad thing" is that on LCD you can see RDS or frequency of the radio station in background. But this won't bother you. And, don't seek your radio stations because, while it's searching, the sound will be muted.

You need to have basic soldering skills and now what you're doing. I'M NOT TAKING ANY RESPONSIBILITY IF YOU DAMAGE YOUR HEAD UNIT OR AUDIO SOURCE!!!!!!!!! AND I CAN'T GUARANTEE THAT THIS WILL WORK ON YOUR UNIT!!!!!

The main goal is to find the line which is connecting tuner output with preamp imput and put a switch which will bypass it. Then you have free preamp input to connect your MP3 player.

Head Unit: Daewoo AKR-1010RC
MP3 player: Phillips HDD-1620

Parts used:
* double KIP switch
* 3.5mm female connector (stereo)
* shielded cables

so tell me this, how would i switch it if my head unit was in the car like it is spose to be? good job on your High school soldiering. make a BETTER system.

@Conasnipes: Is this an complainment or what? This is only an example how can you create an input. You can put your switch and input wherever you want, even outside your car if you want :) My head unit is not in my car, so the best place to put connector and switch was at the head unit's rear mask.

Which high school soldering? We didn't solder in our school, I'm in gymnasium...

Sry on my bad english...

I was just about to dump my unit and get a new one..Thank you for this awesome vid..Done it and it's working perefectly,,found the tuner audio output in the manual.

I did this trick with an old Ghetto Blaster: put RCA jacks in the back, and attached the leads from the jacks to the cassette head lead inputs on the momboard. Then I had a cassette shell that I would drop in the slot to turn the thing on when I hit "play"

[DSM1G90]

With us here in the STATES, we would need a miniature DPDT switch. Or, with a cassette radio, attach the three, 3.5" jack input leads across the leads of the playback head itself, then do a SPST switch across the cassette engage mechanism switch to switch off radio and turn on the AUX. Everything is attached in parallel.

Very cool hack. I'd like to do this with an old pioneer supertuner car stereo and do what you did but also add a line out for an amp or recorder. I have another car stereo which I'm trying to do this with as well. I want to find the line input after the cassette preamp and add a line input to that.

@INJEKSN Do you think there's a way to disable the auto-reverse function of a cassette player? I've searched but can't find anyone who has done it.

[DStud29]

@INJEKSN Great information, thanks! I can't get the url to work, but based on its name I assume it's one of those cassette adapters with a cord on it? I have one, but my cassette player has a broken drive belt, and only plays it momentarily before the auto-reverse flips the play direction back and forth, then ejects the cassette. I originally planned to try to create an auxiliary input point somewhere in the cassette area, but your above comment about burning the mp3 player worries me :-P
