Hey guys I would like to figure out how to make my cell phone work through my car stereo without being fm modulated. I found these part numbers but I number one have no idea how it works or hooks up, and two don't know if it will work in my 2000ls. If you have any thoughts or info please let me know.

that was one of my first posts when i joined and everyone said it couldnt be done. i hope u figure this out.

It's not too difficult. I added a Nokia to my 04. On the back of the radio are three connectors. There are several pins with no wires connected. One of these is the cell phone active signal. Ground it, and the radio switches to phone mode (display says phone, and radio comes on even if off or key was off). This is the pin to connect the cell phone "mute" output from the handfree kit into. Another pin (on a different connector, if I recall correctly), is the audio input to wire the speaker output of the handfree kit into. There is also a ground/return pin matching this audio input, but any ground should work okay. Most ford radios seem to have this feature, but the pins used move around from one model to the next. I wrote down the pin numbers to use somewhere, but I can't find it right now. I thought I had added the info to my wiring diagrams, but I didn't. You can look for the activate pin by touching a 100 ohm (to keep from damaging anything) resistor to ground and then to each of the unused pins, one by one. (This must be done while the radio is connected to the car.) When you hit the right one, the radio will say "PHONE." Then use another resistor to hunt for the two audio inputs. When you hit one, you will here some noise as you touch the pin.
I also recall that Ford sells (higher cost than should be) a harness adapter for the LS that would save you the trouble of finding the right pins, and figuring out how to connect to them. You will still need a handsfree kit to match the phone that you have. It will need to have a low-true mute output and speaker level audio output.

welcome aboard, great first post. can this be done to an 00 ls8. ive been wanting to do this for a while now. please PM me and let me knoe what i have to do to get this to work.

it can be done. let me know how many and how many pins on your radio harness. I "may" be able to pull down connector images/pinouts from alldata.

Let us know! The 04 and up radios are 815 series and totally different than earlier units. I'm not sure these features are available on the earlier units, so I would be very interested to know.

I would realy like to know also. My radio has a piture of a phone on the mute button, this has to be possible.

Sorry I can only get into 2003 on my alldata account (diy account) and the 03+ use CAN protocol for all the add on goodies for the radio. If you don't have an alldata account you should get one. SUPER helpful and pretty cheap.

darn it, I really want this to work.

It should work. I have added handfree phone to an 04 LS, and to a 2000 Grand Marquis. I think that most Ford radios (if not all) that have the phone mute button will work. As was said, the particular pins to use change around from year to year. Yes they do all use the FCP (Ford's version of CAN) bus to talk to the factory phone, but that is not needed to make it work. The only thing that causes, is that when you hit the phone mute button, the radio says no phone and won't mute. Everything else works. (You only get the no phone message if you do have a phone hooked up, oddly enough.) I still haven't found my notes on the 04 radio. The 2000 radio had three connectors (only two populated on some models). The cell phone connections were on the 20 pin connector. Pin 10 is the cell phone in-use signal. Connect the mute output from you handsfree kit to this. Pins 12 and 11 are cellphone audio inputs (12 positive, 11 negative). Connect the speaker output from the handsfree kit to these. Sorry I don't have the pins numbers handy for the 04 radio, but other than the pin numbers the connections are the same. The CAN bus connections are present on both the 2000 and the 2004, but they aren't needed for normal operation.

Go to Radio Shack. Buy a pack of 100 ohm resistors. Wire one side of the resistor to the car's ground. With the radio connected, but pulled out of the dash (doesn't have to be turned on), touch the other side of the resistor to each pin (one by one) on the back of the radio that does not have a wire attached. The resistor will keep you from hurting anything. You'll find that one of these causes the radio to power up and go into cell phone mode. Once in cell phone mode, you can take another grounded resistor and try all the other pins again. Two of these pins will cause noise on the radio speakers. These will be the audio input pins.

BTW, I have the factory wiring diagrams and the factory manuals (from Helm). Neither mention this feature or name the pins used. They list the pins as being "not used." I suspect that the AllData stuff would be the same. This is an undocumented feature, but it is there.

Wow Joe! Great way to join the club! VERY valuable information!

wow, great post there. I will be attemping this. Where would I get a hands free kit for a nokia? Are you talking about just a cheap little haedset?
Eamonn

Go to the Nokia web site (www.nokiausa.com) and look up the handsfree car kit to use with your phone. I think that it is mostly one universal kit that they are selling now. Some of the phones use Bluetooth, and just have to be in the car. Others need a cradle to set the handset in. It is very handy. The cradle charges the phone and is easy in and out. [No cables to plug in and out each time, just a docking connector.] You won't need the speaker that comes with the kit (but you can use the cable attached to the speaker). You also don't need the extra handset option. Some phones connect to an external antenna through the cradle, but most just use the antenna in the phone. If your's has the external option, you'll need an antenna too. Anyway, find the part numbers you need at the Nokia site, then search the web for better prices else where. (You can order direct from Nokia, but they are more than most other places.) Lastly, you may want to go to www.pro-fit-intl.com to get a bracket to mount the cradle on. They make one for the LS that installs without altering the dash any. I can take a picture of mine if you would like.

a friend of mine told me tha his ls ( 05 ) came with a blue tooth phone interface -- i called the dealer and they told me that they can install it for about $400 but the device is cheaper than that -- i saw it at the owners website for the LS and the have it for around $150 and it comes with the instructions to do it yourself but if you do you are going to jepordize your warranty.. im still thinking of letting my dealer do it but if your warranty is done then :q:q:q:q this is great pick-up...

You are not putting your warranty at risk by installing this yourself...unless you screw something up. It's a Ford accessory. Any dealer that tried to shovel that on you needs to be turned into Lincoln.

Ford only makes the bluetooth stuff for the 04 plus models right?
I am currently on the lookout for this kit, I will have hands free done right in this car. Thank you guys for the info, I plan to keep updateing this thread and would appreciate if you guys keep looking back every now and again for advice.

a company called cellport makes plug and play stuff for ford, its easy to install, i going to do mine after xmas. I havnt seen it done in a ls yet but my uncle had it in his 04 tbird demo.

Joegr - where's the microphone? Seperate or part of the cradle?

a company called cellport makes plug and play stuff for ford, its easy to install, i going to do mine after xmas. I havnt seen it done in a ls yet but my uncle had it in his 04 tbird demo.

Got a link? Their website talks about some sort of TCP/IP system for autos, nothing really on-point about cell connectivity.

I broke down last night because of you bastards and bought a bluetooth car kit. When it comes in I will try to wire it up as specified above. I don't know why I am so overexcited about this.....but I am

Did you buy the Ford factory accessory or aftermarket? I think for our year LS's (2000 & 2002) the factory accessories are not plug and play, might be capable of intergration like Joegr says.

The microphone is on the ceiling, between the two map lights. It works very well there. I believe that the factory location is on top of the steering column, just behind the wheel.

I bought and aftermarket motorola kit, I pray it will work.
Eamonn

Ford also makes a mirror that has a microphone in it. I believe it's for their voice activated NAV systems. Rather than buy from Ford, you can get one from MITO or their dealer network. It's a Gentex.

This is a very interesting post I am will probably try this myself soon. Have a question for you guys. I have a 2000 LS w/ the factory phone that I pulled out. Can this port be used so that I don't have to pull the radio out or are these cables going somewhere different?

Now that is interesting! I think a wiring diagram would answer that for you. I'll have to look and see what it shows.

I am excited to try this, if it works then I may go with a sun visor microphone setup.
Eamonn

JOEGR, let me say that you are the man, I have just succesfully hooked up my bluetooth kit and it rocks. I can confrim that on a 2000 ls sport that pin 13 is the mute, and pin 11 and 12 are the input. I put the unit right ontop of the glove box but under the dash. If anyone has any questions feel free to ask, we will be happy to answer them for you.

Nice work man. Post s how-to/tech article or at least some more detail, including the motorola kit you used. So it was pin 13, not 10?

Thanks Joegr.

Does the caller id actually come across the radio screen?

good call there, you are corrrect it was pin 10, I was a little cold and excited when I posted earlyer.
Eamonn

The answer's no on the caller ID. This method of adding the phone does not use the SCP lines, so there is no messaging between the radio and the phone. Ford's add on kit does use the SCP, but I don't think it displays anything on the radio either (other than "PHONE"). The only thing gained that I know of by the Ford kit is that the Phone/Mute button on the radio can then be used to start a phone call. If I ever have the time, I would love to crack the SCP bus for the whole car. I think that a lot of features could be added or modified just by having a controller send the right commands on the bus. As it is, I've had to make modifications the old fashioned way by finding the individual control signals. One that I've made to my Grand Marquis (and will make to the LS when I get time) is power control system that > 1. Powers up the radio and the window controls when the car is unlocked by the remote. (They then stay on for a 5 minute timeout or till the key is turned on then off.) 2. Keeps the radio and the window controls on after key off till the driver's door is opened and then closed (unlike the factory setup that shuts off as soon as the door is opened.) 3. Unlocks all doors after the key is turned off and the driver's door is opened (from inside only). 4. Turns on the radar detector when the car is in gear. Didn't mean to go on like that...
Later

that is pretty interesting.. i have an aftermarket cd player (pioneer).. i wonder if i could still do something like this on my 2000 ls. also i noticed that when i installed the aftermarket cd player now when i shut off the car.. the cd player shuts off right then not when the door is open.

i may switch to the alpine oem cd player, will this give me back access to the disc changer in the glove box and steering wheel controls? also do they play mp3s on that unit? can i even install that unit on a car that didnt come with the alpine setup?

sorry 1 more question - does the alpine oem unit come with preouts for subs with sub control and if so does anyone know the preout of them?

thanks for all this information,

matt

ls4me posted somewhere about that. The timer for the radio is actually in the factory head unit, so the delayed off doesn't work for aftermarket units--it's literally no longer there once you yank the factory unit. I don't remember if he found a way to make it work for aftermarket equipment.

I'm not sure what would be the point of activating the window controls when you use the remote to unlock the car, as holding the unlock button down on the factory remote will roll down all of the windows. Number 2, though, would be terrific--there are times I'd like to keep listening to the radio even after I open the door. Number 3 is available on the new CD3 cars (Fusion/Milan/Zephyr), if you have access to one.

The only thing that causes, is that when you hit the phone mute button, the radio says no phone and won't mute. Everything else works. (You only get the no phone message if you do have a phone hooked up, oddly enough.) I still haven't found my notes on the 04 radio.

joegr -

Are you saying that if you do this mod you lose the ability to mute the stereo? Like if you have a hands-free installed with the mute wire linked to Pin 10, and you hit the mute button it will say "no phone" and NOT mute the system? I'm confused because if it does not mute the stereo signal (CD, radio, etc) then how does the hand-free audio come thru? Or are you saying it does not mute until you press the mute button ON THE HAND-FREE? (that would make more sense and in line with what you wrote - mute on radio no longer works but the radio itself mutes when the mute/start call button on the hands-free is pressed).

If the factory head unit mute button does become useless ('no phone' message) I'm assuming the steering wheel button is the same, no?

Thanks for the great work. Anyone else who has a comment/suggestion on this please do so.

Let me see if I can explain this one clearly, since it is not entirely expected behavior.
1. Once the phone is installed, anytime the phone is active (receive a call, or make a call), the original audio source on the radio is muted (in the case of a CD playing, it is paused), and the radio plays the phone audio through your speakers. [Note that this is not the exact same behavior as pressing the mute buttons.] The volume control on the radio adjusts the phone volume. Note that if the radio was off when the phone was activated, it will come on by itself, even if the key is off.
2. When the call is ended, the radio switches back to whatever it was doing before. (If it was off before, it goes back off. If a CD was playing, it resumes from the point it was at before the call. If the radio was on, it goes back to radio.)
3. Each time the car is started, the manual mute buttons on the radio and the steering wheel work the same way they always had. After the first time the phone is used (call made or received), the manual mute buttons stop working (other than to display "no phone." Using the phone itself will still mute/switch the audio.

Excellent explaination. That #3 is quite odd huh.

Thanks man.

Now is there anyway to get the beginning of #3 to stay that way. I would just like my MUTE button to MUTE. My 2000 LS came with Noah's flip phone. Everytime I use the mute button the phone activates (but I don't have the phone activated, does that make sense :confused: ). Anyways I don't want that piece of junk but my mute button says "NO PHONE" when I disconnect it (and no MUTE). With the phone connected, I get #1 for about 10 sec then #2. ;)

I think in one of your first posts Joegr you say something about grounding a wire. Could you tell me what wire it so I can try un-grounding it.

I just want a normal MUTE button.

"The 2000 radio had three connectors (only two populated on some models). The cell phone connections were on the 20 pin connector. Pin 10 is the cell phone in-use signal. Connect the mute output from you handsfree kit to this. Pins 12 and 11 are cellphone audio inputs (12 positive, 11 negative). Connect the speaker output from the handsfree kit to these. Sorry I don't have the pins numbers handy for the 04 radio, but other than the pin numbers the connections are the same" - Joegr

How do I reverse this......

PS....I've tried asking people at work because they used to install phones in the Grand Marquis (back when Noah drove them from the ark) but last guy to do them retired back in March. :(

First, let me say that I haven't worked on or had a car with the factory phone installed, so read at your own risk. When you say that you disconnect "it", what is it that you disconnected? There is no single wire that remains grounded all the time, so that is not your problem. I think that your problem is that the radio knows that there is a phone attached because it is communicating with it via the in-car data network. You need to find the electronic module for the phone that is built into the car. I have a 2004 service manual, and it doesn't give a location since the factory option was dropped before 2004 (a dealer installed option remains). I have heard that it is somewhere in the trunk behind one of the side covers, but I do not know this to be fact. If you can find it, disconnect it completely. After this it may be enough to turn the car off and then back on for the radio to realize there is no longer a phone. If not, you might try disconnecting the battery for a few minutes. Those are my best guesses on it.

First of all, thanks for the quick response. I when I say "disconnect" I mean the phone itself. If I was to be charging the phone, that is the cord I disconnected. (It plugs into the phone like a charger would).
I had went to the dealer and told him what I wanted. What they did was have the phone connected but hidden inside the centre console. When I pressed the mute button, the phone would come on and it would MUTE the sound until I pressed the button again. This acutally worked for about 3 weeks when the phone got accidently disconnected. I went back and they can't remember what they did so now I have your so called 3 step program in the last post.....:p
I did this a while ago and just lived with it but I stumbled across this thread and decided to give it another go.

I had talked to like 15 different people at Ford about this and NO ONE could help me. And then they wonder why no one wants to buy their cars :eek:
