Step 1: Tools and Stuff You Need
Important: You'll need a cassette player with an auxiliary input.
*This is where we will send the audio signal from the ipod. I was going to hack the tape head connections to send signal there but its sort of complicated and I had the inputs anyway.
Ipod or any mp3 player that can fit on the cassette slot
3.5mm stereo jacks with wires connected
*This will connect the ipod to the AUX input.
*You can scavenge the cassette mechanism for this.
Mighty putty like epoxy
Soldering Iron , cutter, screw drivers, electrical tape, zip ties.
Step 2: Open It Up
Opening your deck is easy, there would be metal tabs to pry or screws to unloose. The top cover usually comes off.
Once opened, there would be "modules" for the radio tuner, amplifier, cassette mechanism/PCB or cd changer.
We only need to modify/remove the cassette mechanism and its pcb.
Your deck should still operate without the cassette mechanism/pcb.
Step 3: Modify Cassette Mechanism
Start building back the cassette mechanism by removing things to open up space for the ipod.
I removed quite a bit of gears, spindles, motors, extra metals and plastic.
Test fit your ipod until you achieve your desired location.
Step 4: Wiring It Up
Solder the 3.5mm with wires to the deck's input connection.
Locate the ACC +12v source. Solder a wire in to it.
Solder the micro switch to the wire from the ACC +12v source and the AUX remote in wire.
*When the switch is triggered, it will make the radio deck switch to auxiliary mode.
Zip tie the the micro switch next to the 3.5mm plug. Make sure that the switch will be triggered when the 3.5mm jack mates with ipod.
Step 5: Setting Up the Docking Station
One you decided the final docking position of the ipod, place the 3.5mm jack /switch in it.
With the epoxy putty on hand make a holder for the 3.5mm jack/switch.
*Make sure the the surface is free from grease and dirt before placing the epoxy.
Let the epoxy dry.
If you have an mp3 player that is smaller, use the epoxy to make "walls" to prevent it from moving around the slot.
You can put some felt paper to protect your ipod from getting scratched or if you have a thinner mp3 player. You can also file the opening of the cassette slot if you want to use other bigger mp3 player .
My ipod fits snugly on the slot. Even with the bumps on the road the ipod doesn't move at all.
Step 6: Done
Once the epoxy dries you are done. Place the cover back. Place the deck back in your car. Done. Enjoy your tunes.
