You guys seem to have gotten away from hacking in at the input side of the chipset. I'm curious about the 14/10 inputs. Someone posted way earlier in this thread that they were unused, has anyone tried these to see if the stereo would even notice and allow it to play through or has there got to be some other trigger to make this a valid selection?

I appologize for my previous sarcasm. I was frustrated and pissed off about other things, then I go and insult a fellow Irishmen. Mr. McCarron if ever we meet I will buy you that stout.

I looked for it too and couldn't find it. I checked the other forum too and didn't see it there.
I was just thinking of the unused Aux input and how to select it. What if a combination of wires, like a keyboard, are used as the switch?

I’d like to investigate the circuit for CD/FM1-2/AM buttons but I don’t have a spare radio sitting around. I would bet there’s a unused button combo to select the “AUX IN” we saw and can’t find.

As for the code in the chip, I’d bet it is all ready there.

I sat and played with button combos and never found anything. I'm betting this isn't a working combo and we aren't going to change the embedded processor code.

It needs to be simple. At some point I'd just buy a new head unit.

^^^^ This write up is taking much longer than the mod did. Sorry for all the delays. I have a young son and he gets more of my time than I do. Not complaining just explaining.

OK I've run into an issue. All my photos are too large to attach 3.--MB..... Help. I will see if there is someway for me to reduce the file size. Sorry more delays.

Here's a free program that is easy to use. You can resize your pix, files, etc as well as do batch re-naming, change resolution, etc...Hope it helps.

Before I start, I would like to say that I accept no resposibility for your workmanship. If you are not confident with your abilities you might want to pass.

Note: I don't know if this overrides the bluetooth, I don't have bluetooth so I can't say for sure. It does override the radio and the CD input.

Just a few things you will need:

4- 4.7 polarized microfarad (uf) Capasitors
Good solder, and flux, use flux on all connections but the board.
22 or 24 gauge wire, length you decide? Enough for 5 runs from radio to jack location
shrink wrap big enough to go over the caps
5 pin connectors (optional) I ran a short pig tail out of the radio to ease further service.
5 pin stereo 1/8" jack, 3 conductor closed circuit, such as RadioShack P/N- 274-246

You will need a solder iron with a pretty small tip. A "Helping Hand", that thing with the allagator clips and a weighted base, about 12 bucks. It will make things alot easier. Radio removal tools, such as finishing nails.

Tools needed:

Soldering Iron with a small tip
Phillips screw driver
Stubby phillips screw driver
T-9 torx driver
T-10 torx driver
Small pick or pocket screw driver
Helping Hands (holding device) optional but very helpful
I think thats about it. I found a small torx bit driver at Home Depot with interchanging bits, starts at 15 and goes down to 4.

1. Remove center console top (cup holder). Remove the screw in the front under the ashtray. Pull up starting at the rear and work forward. Use care and pull close to the clips.

Center console Vehicle Motor vehicle Car Vehicle door


2. Remove the top center dash cover (black piece over the A/C vents)

3. Remove 4 scews from the top trim piece above the A/C vents. Stubby screw driver needed for the 2 on the top. I found that if you pull the trim piece and release the radio retainer springs at the same time the radio pops out easily.

Note: The radio holds the trim in place.

Radio disassembly:

1. Remove the four T-9 face plate scews. Use care, the wire pig tail is short, disconnect it.

2. Remove the 4 T-10 screws holding the C/D changer portion of the radio. With the front of the radio facing away, lift off the changer and tilt it to the left and set it on it's side. Push the locking tab on the wire tape connector to the left and carefully remove the wire tape.

3. Turn the receiver over and remove the 2 T-9 screws from the bottom cover and remove it. The circuit board will now be exposed, use caution not to scratch it. Also use care not to shock the board with static electricity.

4. From the top side locate the capacitors C1528 and C1529. Note the position of the stripe, this indicates polarity. Positive towards prossesor.

5. Set the radio on it's side and heat the capacitor wires enough to soften the solder and straighten the wires, use caution not to over heat anything. You may have to repeat several times to get them straight. Now heat them and pull 'em out. I used a piece of wire to suck up the excess solder.

6. Solder caps to the wire using flux to insure a good clean connection, the replacements I got had wires at each end and marked with an arrow indicating polarity. Use different color wire or mark them someway so you can determine which goes where ie. left and right and polarity. Trim the wire on the caps. down to about an inch. Solder 2wires to the positive end of 2 caps and 2 to the neg. end of 2 caps. You should now have 4 wires soldered to 4 caps.
* Wires should be aprox. 18" long, if you are going to use the 5 pin connector. If you are not using the connector make them as long as needed and feed enough through the radio holes, slots in the back of the radio, to allow you to work away from the radio internals.

7. Solder in the new caps. I don't recommend using flux on the board because the solder could run and cause a short. Work on one area at a time ie. C1528 or C1529.
*If you are not using the 5 pin connector slide enough shrink wrap over the wires to completely cover the caps. and the solder connections now.
Place one cap. in the hole closest to the prossesor with the arrow pointing down, pos. to board. The caps. should be about 1/2 inch off the board. Carefully solder it in place, remember to move the shrink wrap away from the heat. Place another in the other hole furthest from the prossesor with the arrow pointing up, neg. to board. Repeat for the other caps. If you have the front of the radio facing away from you the pos. will be on the left. After all 4 caps are in place, slide the shink wrap over the caps. and all the way down to the board and carefully heat it starting from the board and working up. This should ensure no wires short out after intall.

*If you are not using 5 pin connector skip step 8.

*8. Install connector. You should have all 4 caps. installed with shrink wrap insulating the caps/wires/connections. Feed the wires through the holes (slots) in the back of the radio. Cut wires equal length, aprox. 10-12 inches out of the back of the radio. install the terminals and slide them into the connector, I crimped and soldered them. Remember to note which wire is where.

9. Installing the 1/8" jack. Pin 5 goes to the positive side of the board, side closest to the prossesor C1529 via's. Pin 4 to neg C1529. Pin 2 to pos. C1528 via's. Pin 3 to neg. C1528. Pin 1 to ground. See post 191, but ignore the polarity of the caps.

10. Install the stereo jack and run the wire harness up and behind the A/C controls. Slide the radio into the center dash trim, feed the Aux in harness up through the hole in the top of the radio carrier and behind the A/C controls. Connect the Aux in harness and the hazard switch plug. Pull up lightly on the Aux in harness as you push the radio in so it doesn't get bunched up behind the radio. Fully seat the radio and check the fuction of the Aux in. If it doesn't work YOUR SCREWED. No seriously everything should be fine, if not recheck to make sure the I-pod plug is fully seated and the radio is set to tuner (AM FM).

11. Renstall trim pieces making sure everthing is connected properly.

NOTE: Your turn signals will not work unless the haz. switch is connected.
NOTE: The TC and door lock connectors are the same, I plugged mine in wrong and the doors locked when I pushed the TC switch.
NOTE: Remove the rubber tray liner in the front, under the ashtray, it makes it easier to reinstall the center console cover
NOTE: Don't forget to turn off the I-pod, it will not shut off automatically.

OK thats it.
I have more good pics, but they are too large, if any one needs them PM me.

Again thanks to dede for the mod, and all those that helped figure it out.

If you're still uncomfortable with this PM me, maybe we can work something out.
