Modding XDA II audio out for plugin to stereo...

Hi,
I recently got a car and and want to use one of those cassettes with the cables coming out on it to exercise my grand plan of outputting the audio from my XDA II to the car stereo.
So what I need to do is have a cable that works along the lines of 2.5mm male to 3.5mm male / female.
I have tried modding a spair XDA II handsfree kit I had, removing the head phones and tieing a 3.5mm male jack to it (so that I could retain the mic and dialing abilities) however there was no audio sent down the line in tests.
Is it possible to buy something that meets these requiremnets? (although I would like to retain dialing ability). Or is there some sort of guide somewhere?

You can buy an adapter at www.expansys.com

thanks for the link, I'd like to retain the calling ability tho , hence my wondering bout modding a set of ear phones...

you can get an adaptor which connect to the xda
and have a dongle with
1 mono jack for mic
and
1 stereo mini jack for lineout to pc, stereo, speakers or what ever

There is a very cheap and simple wireless rechargeable device called a Car Baby, this clips over the speaker and outputs all audio to a free fm channel on the radio, no cables to plug in, it also serves as a handsfree for the phone. Look on ebay and search car baby.

audio output
hi..i have an xda2, which sits in my modded xda car kit cradle, and there are is a jack plug [fem] with the kit which outputs all audio..i made a lead which plugs into my aux input, on my head unit, and bought a 1gig sd card, and loaded up my mp3,s...it rocks. on the subject of modding ur headset..that should work.....however, the wires are covered with a laquer...before u connect them...strip them and hold a match under them and burn off the laquer...it will work, i tried it first!

Right, 2 things to check out then, Car baby and the toast the wires method. Roll on this evening...

When checking car baby make sure it is the rechargeable type.
Here is battery type, costs £1.99 plus post

If you get one of these make sure your phone/pda is on low volume when tuning, then adjust until clarity is best, if you have too hig volume on phone/pda it will distort the audio.

3way-stereo to FM transmitter
This works:

You just have to be careful wiring the 4-way XDA jack to the 3-way stereo socket for your FM transmitter

Mini USB > 3.5 Jack?

Any adaptors that will allow me to use proper 3.5 inch headphone jack in place of the mini USB ones ( i dont like the in ear phones) checked ebay and couldnt see anything?

you want get one of these http://www.expansys.com/p.aspx?i=142090 - Mike

Ouch, that thing is both horribly badly designed and prohibitively expensive- it's going to stick out what looks like an inch by itself, most headphone plugs will add another inch on top of that- I need something that fits flush with the bottom of the phone (comes out at a right angle) AND supplies an input for the charger. One can only dream!
The orbit would make a great on-mains Wifi internet radio if such a gubbin existed- hook up some speakers, start TCPMP, sorted!

in which case if you don't like wires stop messing around and get a set of A2DP compatible headphones - the quality is very good, but far more costly than a cable addaptor - the choice is yours - Mike

Might have been worth while if I didn't use an iPod for all my portable audio needs- have you seen any A2DP compatible speakers around?
Looks like there are hacks out there, but no official products, the combination really would just turn the Orbit into an incredibly expensive Wifi radio! But where's the fun in just going out and buying a proper one!

Have a look at the products made by Parrot there are a few Bluetooth audio add on boxes, I fail to see the relevance to WiFi?? as the A2DP profile is Bluetooth - it even works on the T-Mobile MDA-CIII which has no WiFi - Mike

I say wifi radio because I listen to internet radio stations around the house using the Orbit, and the ol' tinternet comes via the wifi doohickey!
A2DP is, of course, a bluetooth profile and would be the method over which I get decent sounding audio from the Orbit to some speakers whilst still having the Orbit plugged into mains so the battery doesn't get sucked dry... that said I think the Orbit will last a good few hours streaming internet radio, although I have yet to put that to the test.
My other solution would be, as mentioned above, an adaptor that allows both the charger AND headset to be plugged in- I can't see this as being technically impossible.
With a brief cursory investigation I have discovered, I think, that the headset uses a proprietary 6-pin connection on the opposite side of the mini-usb connector. The headphones do not use the 4-pin standard mini-usb connector on the other side, but a connector that uses both should be reasonably simple to produce. Ergo it should be childs play for a third party to produce an Artemis dock that contains not only a connection to USB but a standard 3.5mm amplified microphone socket alongside a standard 3.5mm amplified stero audio jack... not to mention a button on the front of the dock for picking up calls and a volume slider if you really wanted them.
Call me crazy, but I want one of those!

Might do the trick even if it is a bit long

Dear lord! You've made my day! Hmmm, a little jiggery pokery and I might even be able to incorporate that into a dock but it'll be fantastic for charging and listening to net radio at work- takes that little extra load off my desktop PC.
Cheers!

Glad I could help

Hi,
Does anyone know if the above would work with a set of mini stereo speakers with a 3.5mm headphone jack (like the walkman speakers i used to have, back in the day...) to listen to the FM radio while charging the phone from mains? Or would you still need the headphones plugged into get any FM reception?
Daft question maybe, but I wondered whether the device would just use the speaker wires as an antenna instead of the headphone wires?

It will work fine, I am going to use mine to connect my orbit to my home stereo and charge it at the same time.

2.5mm 3 pole jack plug
Hi,
Anybody know of an Artemis mini usb to 2.5mm 3 pole jack plug adapter which allows the connection to deliver audio and microphone capability ?
I would like to connet my Artemis/Orbit to the Autocom intercom system on my motorcycle . This uses a lead with a 2.5mm jack plug at the phone end and a 3.5mm jack at the Autocom system end. Both are 3 pole.
Thanks
P.S. hope you don't mind me jumping in your postings

Is this so you can listen to music from the Orbit? I've had difficulty on my bike with this...music cuts out and wont restart after phone call is over. In the end, I bought the Autocom bluetooth dongle and now bluetooth the Orbit to the bike. I get phone calls and GPS just fine, but I use a wired iPod for music.

Does this support the Artemis? It isn't in the list....

There was a posting for the mini USB PinOut some Time ago. Look in the wiki Section to find it. Here is what they showed up with.
Maybe This will Help someone to build their own Adapter or whatsoever.
Greetings
Jabami

so what was the general concensus with using Autocom? Did the 2.5mm jack work?
I want to avoid using the bluetooth option on autocom, since I might just as well go for a Scala bluetooth headset instead if the jack doesnt work...

Hands Free Carkit Set Up

I see alot of people looking for hands free set up in cars that don't have bluetooth. I have looked around for awhile and finally found something that works for me perfectly.
To hold the phone I am using the HTC OEM dash kit. I have used universal kits and wasn't satisfied. below are some pros and cons of the HTC OEM Kit.
Pro:
- No need to plug in a charger, just put in dock and you are ready to go
- Being able to go from portrait to landscape or vise versa without messing around with hinges or knobs.
- It feels sturdy and secure
Cons:
- Can't use a case with it. The phone fits the dock bare naked only. I use seidio active case and I just slip it in after I take the phone out of the dock.
- The back camera is blocked.
To me the pros out weigh the cons so I love this dock.
To play music through the stereo I used to connect an aux tape player cable. But that's one extra step plus the wire can get messy so I have been looking around till I came across the Satechi Bluetooth hands free fm transmitter. This has solved my problem. It has a 3.5 mm connection on the side where I connect the cable from the tape player to it. While the connection to an FM is superior compared to other fm transmitters in the market the sound of an aux connection is alot better than using the unit to transmit to fm station. So now audio and phone calls are transmitted from the phone to the unit using bluetooth and the unit transmits that audio to the car using the aux cable. As soon as I get in the car and turn it on now the phone is connected within a few seconds. The unit also has a built in microphone. it also has a USB cable connection to charge your phone. One con that I found is the unit has only three buttons, call button and two buttons to change the FM station. Therefore no buttons to change tracks. The call button can be used to play or pause but never got it to work properly. So I just use the on screen buttons on the phone.
I have attached a picture which shows the dock on the dash and the bluetooth unit in the cigarette lighter. I hope this helps for those that don't want to get a new head unit to play audio wireless and looking for a dash kit.

Thanks for the review.
Imma thank you .

Any chance of getting a picture of the "3.5 mm connection on the side" & and more detail on how the connection is made to the tape player? Does your tape player already have the port?
TIA!

Arc S earphone jack configuration

does anybody know of a software solution like an app or some other hack to make the earphone jack on the Arc S compatible with aftermarket earphones having a inline mic?
background --
The headphone jack on the Arc S is different from those found on motorola, iphone or HTC phones. The four connectors have the same configuration for the left and right audio channel but the connections for mic, ground are interchanged. 99% of the earphones with inline mic available in the market are made to the iphone specs and hence are not compatible with SE arc s. I have these ones and these, but when i plug them into the phone it just says "accessory not supported" .
I had the same problem with my last phone samsung wave which also has the flipped ground/mic connectors. The earphone that came with that phone also work on the arc.
There are cables available that fix this problem -- http://www.amazon.co.uk/gp/product/B005I0GHV8 (I have bought this one)
http://www.meelec.com/MEE_TRRS_Adapter_for_P_Version_Headphones_p/adptr-trrs-35.htm
http://www.kvconnection.com/product-p/km-354r2m-r3f.htm
galaxy s users can use an alternative voodoo sound driver to mke the earphones compatible without the need for additional adapter cable.
can something similar be done for Arc S? , (I have bought one of those adapter cables but it sucks to have it dangling from the phone all the time)

base on my experienced, you can try this.
SE supply the wired Handfree kits right? along the kit got
1. stereo jack with mic inline (you should notice the jack has 4 metal/copper connection to be plug in to the phone)
2. in the middle have mic and an answer button + another Stereo jack receiver,
3. after that, then you will have a bit short wire stereo earphone with a stereo jacks but without the mic inline wire (you should notice the jack has only 3 metal/copper connection)
you should connect your wire input device to the stereo jack after the mic, because after the mic only the circuit will only supply sound output voltage (+ left, + right & -ve for both earphone)
...i am sorry for my bad English
goodluck
-ALi

@putrabiru
you seem to have misunderstood the problem
earphones that don't have a mic in them(3 rings on the jack) already work fine if connected directly to the phone.
I am looking for a way to make earphones with inbuilt mic(4 rings on the jack) work with the arc without an additional piece of wire between the phone and the earphone jack.
So i am basically looking for a way to make the phone treat the mic and ground connectors opposite to how they are set up by default. This will definitely require a kind of mod to the system files of android or the drivers. I've even read about other users of samsung phones who opted to physically replace the headphone jack unit on their phones with standard configuration ones!
Sony should have kept the configuration the same as how most earphone manufacturers make them.

Sony actually uses the agreed OMTP standard for mobile headsets. The reason for all these problems is nothing other than the recent popularity of crApple.
Just get a cheap OMTP adapter off ebay. You should be able to find one by searching for something like "Motorola headset adapter" etc.

As Paul stated, Sony Ericsson actually followed the standard, Apple did not. I would suggest to look for an adapter if you want to use "iPhone compatible" headsets.

DIY FM Antenna With 3.5mm Audio Jack

This is not something new and have been shown many times in YouTube. It is interesting to have for any phone with 3.5mm audio jack that can be easily done within a few minutes. I do not use my headset with my phone so this would be a nice hack to have around to listen with your friends on some local radio without consuming your data plan and phone battery.
Find a headset that you do not need. We only want the part with the 3.5mm audio jack. Just trim it down to about 20cm in length and fold it in half and tie a knot at the end. I tied a lasso knot at the end just so I can adjust the length of the receiver later on though it may not help much in reception quality.
Tested several length from 1 meter all the way to 20 centimetres and found not much difference in reception quality for a fact that you will be using your loudspeaker to listen to the FM radio. The same with whether to loop or not to loop the receiver but looping the receiver gives it a cleaner look while maintaining the same reception frequency.
Putting your phone too close to a human body greatly interferes with the FM signal. On the other hand, placing your phone on a metal table may enhance the FM reception.
Perhaps those who have knowledge in electronics can shed some light to optimize this simple hack further.
Have fun...

I didn't know. Works like a charm !! Thank You

Doesn't work for me. When I plug in the trimmed headset cable with the ear pieces cut off, the FM App keeps asking me to plug in a headset. Works OK when I plug in an untrimmed headset and switch to speaker in FM App menu.
Is there a further trick to getting this to work? Are you using the stock FM App?

I had the same problem myself, and it stems from the fact that smartphones will interrogate any headset you plug in to check if it is suitable. There are basic stereo headphones with three contacts on the jack plug (from the tip they are left, right and ground) and should work on any phone regardless. But there are two variants of headset (i.e. those with a microphone) that use four contacts, the difference being whether they connect the mic on the third or fourth contact.
As of 2016 most manufacturers have standardised on one system (left, right, mic then ground), but there are enough older phones and matching headsets out there that use the alternative pinout scheme. For example my old Sony Xperia used L-R-G-M (the same as say Blackberry), necessitating the use of an adapter for certain accessories. My latest Z5 however, has moved to the L-R-M-G pattern, which means I can no longer use my favourite old Sony headset anymore, not even as plain headphones, the Z5 just refused to talk to them.
That explains why a dumb wire might not work with a smartphone, because it is looking for a signal loop on all four (or three) contacts to try and figure out what's been plugged into it. The solution is to short out the wires to fool the phone into thinking there actually is something on the other end. Simply bare all of the wires at the cut end of the cable, burn off the fine lacquer or cotton that is used as an insulation, then twist the wires together to short them all to the ground. Better still, solder them together and cover with a bit of heat-shrink for a proper finish.

Found some pre-made antennas in ebay, you can try searching for 3.5mm antenna. They look pretty decent. I am also looking for compatible antenna, if any, that is compatible for steven303's new headphone jack.
Edit: did some research and found that the 3.5mm steven303 mentioned is called '3.5mm 4 conductor' or 'TRRS antenna 3.5mm', you can try searching for them in ebay or look for similar ones lying around with wires long enough to be loops around to be used as antenna for new phones with the new type of head jack.
I got two item I think can be suitable for this purpose; search with the following keyword in ebay;
1. 3.5mm 1/8'' Male To Male 4-Pole 3 Ring TRRS AV Audio Extension Cable 1.2M/4Feet
2. 4-Pole 3Ring TRRS 3.5mm (1/8'') Male To Female AV Extension Cable 3FT/1M Black

I have an additional issue. I use my phone's fm radio feature with an old pair of headphones for an antenna and listen via blue tooth headphones when I'm running or just working around the house, etc. My problem is that as the phone moves around in my pocket, the movement causes the phone to think the headphones came unplugged for a second and the radio turns off. When that happens I have to take the phone out and turn the radio back on. This happens often enough that it is a pain in the neck.
A separate but related issue. With some old, non functioning headphone cables the phone doesn't think there is anything plugged into it. I am lucky in that my phone gives me the option to "Play anyway through speaker or bluetooth". So even though it thinks there isn't anything plugged into it, I do, and I have good FM reception.
Here is what I want: I want to know what to do to my old headphone wire so that my phone doesn't think there is anything plugged into it when it is, in fact, plugged in. I hope that makes sense!
