NOTE: This solution may not be for you for various reasons. I respect that decision and your opinion and ask that you respect my opinion and those that are looking for this type of solution.
So…I have been quiet lately because of my life changing so significantly in the last year. I sold my car
, bought a truck, bought a house, got married, and had a child (not in that order). I know many of you have been wondering what the heck happened to my Aux-In Solution?? Well…I am here to tell you that it is finally complete and I have successfully created a true audiophile aux-in solution. All of the kinks have been worked out; as of today (9/24/07) it has been successfully installed into 4 vehicles.
WHY BUY YOURS OVER OTHERS:
Although my board has a slightly higher cost, it is the more professional way to achieve a true aux-in. It is the closest that you can get to an OEM install without purchasing an 07 radio. You no longer have to sacrifice a CD slot for a silent CD which is especially good for those who only have a single CD player. Also look at the following link for a comparison of the various Aux-In options that you have. Various Aux-Input Options Comparison Chart
You may be wondering how this works? Well…using a combination of centerpunch and ipoduser I am taking the FM audio input and switching them with my input board. I also use the extra momentary switch (4th position on the AM/FM/CD button) to toggle between Aux-In and Radio.
WHY IS IT MORE EXPENSIVE THAN JAZZY’S:
Jazzy’s board is your basic electronics board. There aren’t any relays or complicated circuitry with his board. I have also gone through 4 revisions of this board and have a lot of money/time invested in it. The cost of parts for the board is $65 so I am not charging that much over cost (since it includes shipping). The relay alone costs $20.
Although not publicly available, I have gone through 4 board revisions. No, I don’t have any boards available for the previous revisions, but would be willing to sell the schematics for those if you want to buy them?
GROUND LOOP ISOLATOR:
- Similar to Jazzy’s board (where do you think he got his idea) but I didn’t like the silent CD or muting problems.
- Relay switch added and RC Debouncer and latch for momentary switch but still using CD cable. Able to use any CD, but still muted at certain points <- didn’t like.
- Added a mute line to the mute pin on the CD Changer cable. Still muted when changing discs. Still muted when changing discs and some other functions. Still not good enough for me.
- Current iteration. Since I was unable to reverse engineer the CD Changer Bus, I went the ipoduser rout and used the FM audio lines.
Because I don’t know what kind of grounding your individual electronics are using, I HIGHLY recommend getting one of these(available at WalMart, RadioShack, BestBuy, etc…). I am not including these, because I don’t know how many people are actually interested in this board and I don’t need to invest anymore money in this if no one is going to buy one.
The cost of my board is $75
for the board and parts including shipping. If you are paying by PayPal, the cost is $80
to cover PayPal fees. Please PM me for e-mail address or contact information.
Because of the additional time it would take me to assemble the board, I will send you all needed parts and instructions and you will have to solder the parts onto the board as well as install the board into your radio. Instructions for soldering as well as installation available at the end of this topic. If you have ever soldered a modchip or worked on PCB boards, then you should be able to install this board.
WHAT DO I GET:
HOW DO I SWITCH:
- Input Board
- Resistors, Capacitors, Transistors, Relays, Screw-down terminals (all parts labeled in bags)
- Soldering Instructions (available below)
- Input Board Installation Instructions (available below)
- White, red, blue, and clear 30awg wire
- Black, Blue, Green, Purple, Red/White, and two shades of Red wire
When you want to listen to your Aux-in (ie iPod), press FM to put your radio into FM mode, then press the hidden “SAT” button to switch to Aux-In.
There is NO CD Spin because you aren’t using the CD changer cable.
You can definitely use this on ANY vehicle. The caveats are:
AVERSE TO ELECTRONICS:
- You will have to do the detective work to figure out what the FM Left and Right inputs are.
- You will need a momentary switch (can be externally mounted).
- You will need to figure out a chassis ground, power ground and a 12V Power connection.
If you want someone else to install it: Gas711(at)cox.net is willing and very capable of installing this Aux-in board. Cost will be $100 with shipping paid both ways by customer. Radio is tested before and after installation. Turnaround is approximately 2-3 days. You may contact him at the above e-mail address with any questions

Please be patient as I have most of the parts for 90 boards on hand, but still need a handful of resistors as I am unable to foresee demand for this solution. I don't want to purchase any additional items if people are not interested in my solution.
