Memory erases everytime the ignition is turned

Check the Audio Cassette Tape

1. Make sure the cassette tape is compatible with your device. Note: Some cassette players won't play High Bias or Metal tapes.
   
2. Remove the tape from the cassette compartment. WARNING! There is a risk of hardware damage when you force to remove a stuck tape from the cassette compartment.
   
3. Use a pen or pencil to turn the cassette reel and reduce tape slack.

Check the Cassette Player

1. Remove the tape from the cassette compartment.
2. Clean the tape player head and drive mechanism. Use a dry cotton swab to clean the surface of the pinch roller, play/recording head and erase-head

If you only have one set of tape in/out connectors, then hooking up two tape decks and an equalizer is going to be difficult. You could hook the "tape out" to one tape deck, that tape's output to the second tape, and the second tape's out to the equalizer, connecting the output of the eq back to your receiver....

I would start by disconnecting the radio and hooking it up right,the power should go through the ignition switch.So that when you turn the car off the radio will go off and to hear it on again you have to turn the key to accessory or start it.That might take care of a few of your problems.

Outs to Ins.

its the yellow wire

You must have tied into an Accessory fuse and not a constant. Typically Cd player/radios etc will need both an Accessory tap as well as a constant tap.

Test the voltage on the wire and if it's constant you will have 12VDC without the key in the ignition You will also need a tap where there is 12VDC ONLY when the key is in ACC mode (or ignition on)

I do not have specific details on your CD Player but consult the manual on adding both of these connections,

I hope this helps

Hello Trevor,

Easiest way I can think of is as follows:
1. Connect the "phones" of your cassette player to the "Line in" of your PC. Line In is coloured blue, you will need a a 3.5" to 3.5" male audio cable.
2. Next, install some sound capturing program on your computer. I can recommend Audacity: http://audacity.sourceforge.net/
3. Start the cassette player, check the volume levels, do some short test records. Once you are satisfied with the result, rewind and record side A of the cassette, then side B. Using again Audacity, you can cut the desired parts of the record and save them in the format and quality you like, I guess *.mp3.
4. Burn the files to a CD. You can use CD Burner XP Pro: http://cdburnerxp.se/

I hope that I have been very helpful. :) 

check your cables to the units channel that doesn't work, for breaks. Does the cassette player play back a pre-recorded tape okay? if it doesn't there might be a internal fault.
Check the wires to the tape head to see if one is off.

this is not a sales pitch but i purchased the correct patch harnass from pmr, it should be available at any good sterio store for about $10

Why not plug the cassette directly into the CD recorder? Are they trying to achieve some eqalization change? If not, then this should work. It's all analog at tape level.
