Step 5: Do it all in reverse.
Plug in your Ipod,or other Mp3 player, CD player, or anything else with a headphone jack.
Pop in a tape. I used an old weight loss tape. You won't be able to hear the tape unless you turn the volume way down. I suggest turning up you Ipod no more than 2/3 of the way, and then use your car stereo to do everything else.
You can adjust your volume, fader, balance, bass, treble on the radio itself. If you want to go back to your radio all you have to do is leave the tape in and push the FM button. It's that simple.
