What are your thoughts. Seems like a good product. Be able to use some decent headphones for listening to those mp3z . . .
Anybody used one of these?

is the answer/mute button only for those 2 functions or is that module also acting as a microphone (don't think so)? looks good to me but i use the headset adaptor i bought from this internet site based in hong kong. check out:
http://pc-mobile.net/pxdaa.jpg (the website is http://pc-mobile.net)
it comes with a standard 2.5 mm jack for the xda. the wire is on a retractable mechanism to avoid tangling. at the other end is the stereo phone jack which serves as an answer/end button and as a microphone as well. there's a single headphone jack connected which uses a 3.5mm plug. when you want to listen to the toons using your 2-headphone set; you simply unplug the jack and insert any 3.5mm plug-based headset. in effect you can use any 3.5 headset as handsfree.
costs 26usd but services are 5-stars for me.
cheers

Anyone tried this adaptor from pc-moblie.net? The sound quality is good or bad?

i doubt that it could damage the quality so you can hear it unless you connect it to a stereo's lineIn and play it out using real speakers
those headsets are too limited imho to take much damage from a few connectors

However, all these things are not suitable for xdaII.
I bought one from pc-mobile and the quality is good. However, since the new xdaII got 2 buttons in its handsfree design, this product from pc-mobile is not fully compatible. You can hear from it but you can't pick up or end call from it as compared to xda1 you can.
I hope they can produce another product which is fully compatible with xda2. Otherwise, I may have to go for bluetooth but really worry about the battery.
Also, can I or is there anyone using the bluetooth handsfree for mp3 playing????? I doubt that very much.
I do really like the pc-mobile handsfree which is retractable and handy.
Any alternative in the market?? You got the adaptor but I think its only good for audio MP3 listening. If you attach another headsfree to the adaptor for business use (don't know whether we can...), you will have 2 buttons (one for the adaptor and one for the handsfree) which is quite funny !
Does somebody else have this problem and find a solution?
Do most people use bluetooth?

*Damn* !
Been creating a cable myself, tried it yesterdaynight late....
The damn thing didn't answer the phone when i pressed te button.
I cut the audio-out cord and trew the cable away, because i tought the mic didn't work....
Now i read this.... Guess the mic did work, but the answerbutton didn't.
Now i hope i can rewire the audio-out cabels again, so i haven't been soldering for nothing last night

Headphone adapter for HTC magic
Hello.
On the HTC magic, there isnt a 2.5 or a 3.5 headphone jack! there is only a mini USB jack. Does anyone know where i could get a mini USB jack adapter to turn it into a regular headphone jack?
Even if anybody knows what kind of mini USB jack comes on the HTC then that would be lots of help! because ive already purchased one that fit, but didnt work so it must have been a different type.
Thanks in advance!

Wiring my own car kit..

I'm trying to wire my own car kits for XDA 1.
As there is no way i'm paying the prices asked for the proper car kits.
I already have an in-car holder with a connector fitted for my GPS, and I wish to solder in some more wires to link phone features in.
I've done some searching around the site and this is the info I've figured out so far..
Pin 1 for Microphone Input
Pins 3 & 4 for Audio Out
Pin 19 to tell XDA its in car mode
So my questions:
Are pins 2 & 5 the grounds for the Audio out ?
My car stereo has line inputs (phono connectors) can I just rig up these connectors to Pins 3 & 4 (with grounds) to get audio out ?
I have a phone mute wire on my stereo, what do I hook this upto, so that music will mute while in phone call / getting navigation instructions?
Thanks
Neil

Take a look at http://www.xda-developers.com/connectors/
There you can find all about the connector. Ground is ground, so you can use Pin 2 & 5 for your Audio.
Telephone mute at your car stereo won´t work easy. There is no pin at the connector that is used when a phone call is getting in.
The original car kit does this in a black box, that mutes every time a signal comes from the xda.
Just search a bit in the forum....
HTH
Stefan

Thanks already had a look @ the connectors page, its very usefull.
I've done some more searching but there are still a few things needing a bit of clarification.
1. Do I need any capacitors or anything else in the line from XDA to Line In on my car stereo?
2. Could one of the audio out feeds be split to also give the mute signal. If so how could i convert it so that the feed is Ground when outputting, and live/dead when not ?
Cheers
Neil

Anyone ?

i have my audio out direct to my line in on my car stereo
i have a mono analog sound amplifier for the mic in (using a carkit mic)
you dont have to do this, just dont put pin 19 to ground, and audio will go through the line out of the connector as well. you can just speak and the mic is fine for xda1
xda2 is very different , had to rewire everything
just take 4 or 5 GND wires from the connector
bundel them to 1 GND and put it to the - of you car

Thanks mate,
Can I just check a couple of things to make sure I don't kill my XDA or my stereo
1 - Nothing is required inline with the audio out 2 line in cables, they just hook straight up ?
2 - Only connect Pin 19 to ground if I don't want to use the internal mike?
Can anyone recommend a small mike, I can fit in the car to use with this setup ?
Cheers for all your help :wink:

^ Up we go

a external mic is a lot off trouble to build in
i can tell you that
if i was u and got a xda1, i would nog ground pin 19
use the internal mic
yes, just hook gnd and line 3 and 4 (audio?) directly to you line in of your car stereo, i think its stereo dependend. its a analog stereo sound wich is produced by your xda1, i have a line in for gps or dvd player audio on my stereo, so that works without any problem, clear sound
i have a nokia microfoon and a mono sound amplifier as a line in to GND and pin 1

Thats brilliant cheers mate,
I am really wanting to try putting an external mic on as the phone is mounted down low and quite a way from the drivers head so i don't think the internal mic would pick up clearly..
What size amplifier do you have for your mic ?
I'm thinking maybe getting a handsfree mic and mounting it up by the drivers head, would something like this be suitable to use with that? : http://www.maplin.co.uk/products/module.asp?CartID=031221163652177&moduleno=2904
Thanks for all the help

i have something very similar like that
for my xda2 that is
maybe if you havent started the wirering and soldering. you could do like i did
get a LPT printer connector, it has more then sufficient connectors for each wire, and they have numbers!
ideal. for future plans.
then i just get a second connector and solder that to every componnent

Great!
If it used a tie-clip style microphone would I still need to use an amplifier with it, as I imagine the pickup is reasonably good on them..
Is 2.5W enough ?
Many Thanks :wink:

i dont know with xda1, if i connect a portable mp3 player to my xda2, i must set it to at least 2/4 of volume.

@akira :
I'm wondering where to connect Pin 19 to ground...
Can i just lead one wire out of the connector and ground it to the car, to the ground of the audio (pin 2) or should i connect it to another ground on the connector... ?
Btw, i disconnected the org. ground from the connector from pin 2 (less noise)... So i have onder Ground-audio out on pin 2...

jpiek: Have you made your own kit ?
I would be interested on how you done yours, how you rigged your microphone up etc..
Cheers
Neil

Not yet, i used to have juts audio-out from the GPS cable on my XDA I.
For the XDA/MDA II i need to ground Pin 19. I still haven't done that since i don't have a external MIC.
Now i wish to be able to ground pin 19 with a switch. If "on" it will shorten the connection and use audio-out (for TomTom). I hope to be able to use the BT headset for phone.
If i don't use audio-out, i can disconnect Pin 19 and use the inernal mic for voicedail etc....

Are there any news on that topic? How can I generate a mute signal?
thanks
Mütze

Hi,
I have a SPV E100 what should be simular to the XDA's. I want to to nearly the same. My setup should work with a Safe2talk Handsfree Kit where I want to connect the Speakers/Audio to the Navigation/Phone in of my Blaupunkt radio. I also want to use a serial GPS receiver. I read different articels in this forum but could not find a answer to my question.
How could I realize a mute funktion?
Cheers

Earphone Adapter

Me again
I am looking to purchase an adapter to plug into my Qtek 2020i so that I can plug a FM transmitter into allowing me to play the MP3's to the car stereo.
I don't really fancy the idea of a 3.5mm to 2.5mm all in one unit, high change of breaking the 2.5 in the phone.
I have read around and there are adapters available that are a 2.5mm plug with a cable then the 3.5mm socket, but there seems to be problems with some of them not being connected correctly and thus, not stereo, not working etc.
I'm not bothered about bringing the microphone out, I have bluetooth and otherwise I'd be using the internal mic.
Any thoughts guidance anyone?
Tom

Hey Tom
Me too, if you find some information, please post it here.

Well what I do know is that Expansys stock such an item. However its in the £7-9 bracket, which strikes me as stupid. For that much I can go and buy an inline socket, a plug and a mile of wire and make it myself!
Infact for that much I'd look at buying a stack of inline sockets and plugs and make and sell the buggers!
Tom

I bought an inline 2.5mm-3.5mm adapter, and I had to cut away most of the plastic surround at the 2.5mm end to get it to fit. It was a bit dodgy anyway, might've broken the socket, so I got a 2.5mm right-angle jack to 3.5mm socket (along a short cable, just enough to run up the inside of my case and out the top) for a few quid. Still had to cut off the extra plastic on the 2.5mm end to make it fit though.
Not sure if this disables the internal mic, since I only use it for listening to music, and then unplug it when making/receiving a call.

Strange, I bought mine for about £2.50.

Hi,
I bought a 3.5mm FM transmitter powered by AAA batteries or Car adapter for $11 on Ebay.
Then I bought an INSTEN 3.5mm to 2.5mm stereo adapter with Mic and answer button for $7
This way while listening to music on my car stereo, if a call comes in I just press the mic button on the adapter and I can answer the call by hearing the caller on my car speakers and talking into the omni-directional mic on the adapter. My total cost = $18
It avoids the hassle of unpluging from your PDA phone...which could down the road cause problems with your PDA.
Look on ebay for these deals.
Thanks

can anyone help with wiring connections

Being a deaf old git (not totally but my hearing is not as good as I would like), I want to add a pair of apmlified speakers to the PDA so I can hear the voices in my Tom Tom on the Apline clearer since the socket is a 2.5 stero type plug does anyone know which is which on the connections please?

you should read this
http://forum.xda-developers.com/showthread.php?p=1526625#post1526625

I presume your referring to the Garmin 2.5mm to 3.5mm Jack Adaptor?
nice but not what I was really after
I have found a small set of speakers with a 3.5 jack on the end all that concerns me is the standard headset that comes with the IIi is headset and mic I presumed that a common return (usually the last outer connection and I imagine one of the terminals is for sound and one for mic if so it means only mono sound which is different to what I have been lead to believe just need to know which is the sound out connections on the plug so I can buy a 2.5 plug and wire them up.
The other thing I suppose is I could get a bluetooth headset if the sound from the Tom Tom comes over that but that is a unknown also

i was not talking about the post i made in that thread but more about the DIY stuff people were doing
more about the connector wiring here
http://wiki.xda-developers.com/index.php?pagename=Connectors

that would have been exactly what I wanted only thing it wasn't for the Apline unfortunately

Audio connections on himilaya and alpine are identical.

then one of us is wrong as the connections shown are on a FOUR pin connector my Alpine has a working THREE pin connector

not sure about alpine but i had no probs using my old wallaby headset and cradle on alpines sibling called himalaya

Well I seem to be a blind old git because I just noticed there is a inset on the plug and it is a four connection job sorry guys I only recently got given this thing and a quick glace it looks like three connections but one is inset behind the shield

The 2.5mm connector on BOTH Alpine & Himalaya can accomodate either a stereo or a 4-pin 2.5mm connector.
If the PDA detects a 4-pin plug inserted, it assumes the standard wired earphones and mic are connected, and bypasses the internal mic and routes stereo audio to the earphones.
When a normally-wired 2.5mm stereo plug (or adapter to 3.5mm socket) is connected to the PDA, it just outputs stereo audio.
I use a small 2.5mm stereo plug to 3.5mm socket adapter (having shaved away some plastic to enable it to fit, the socket is inset slightly) - to connect up a standard set of ipod-type speakers to the PDA, and it works a treat.
In short, either obtain a small adaptor to standard 3.5mm socket adaptor or if you get a 2.5mm stereo plug that fits nicely (Maplins, Radio Spares etc) and you want to solder it up yourself, it follows the same wiring cnventions as it's bigger 3.5mm brother, so a wiring diagram is just a google away.

Nexus6 hard-wired car dock help.

I am thinking of replacing the stereo in my car with a dock for my Nexus6. I was going to just buy a new head unit for Bluetooth connectivity and hands free calling on the road. Then i thought why spend money on adding a layer between me and my phone since i don't use my radio anyway.
I have seen lots of write ups and videos of how to replace your stereo with a tablet. But the one thing I have never seen anyone do is add hands free calling for their phone.
I am hoping someone can tell me how to wire a mic in to a USB cable as I also take audio out to run to an amp and power in back to the phone. I am aware I will not have fade control just balance and I am good with that.
I am aware that I will need to run the output to an amp and my Jeep has one from the factory. I am not worried about wiring in a converter to supply power and already have one that charges the phone while using gps and play music at the same time and a dedicated fused circuit activated by relay so there are no issues with battery drain. I will build a custom dock with a USB cable mounted in it in the dash in place of the removed stereo. I plan on using one of the wired mics you use with an aftermarket pioneer stereo mounted on the dash. The specs for it are Polar pattern: Omni directional Mic diameter's 9.7*4.5mm Sensitivity:-47dB+/-2dB Frequency Range: 20-20KHz Output Impedance: ≤2.2 kΩ SNR: >58dB Standard Operation Voltage: 4.5V Operation Voltage: 1.0V-10V.DC Wire Length: 4 M Ref Pioneer part no: CPM1064 CPM1084
What I need is someone to please show me how to splice the cable so I can add rca connectors to audio out, mic in, and power in and have it work. Or if that can't be done I can add a qi charger to the dock if I can wire the speaker out and mic in as a usb headset and make that work. Or if I need to add a signal booster to the mic input to make it work please say so and give me specs to go find one.
Thank you in advance for any help or useful suggestions.

A hard card case or soft case with a metal 1 cm below the M-logo. A neodymium magnet on the dashboard. No car kit needed. The speaker of the N6 is loud enough for use in a car for navigation and phone. Same with microphone.
Option is to use a phone jack converter to connect the N6 output to the radio.
An example how I used my N7 in the car.
http://forum.xda-developers.com/showthread.php?t=2137636/ - post #65
Note my N6 case has metal at the outside and below the M-logo, because behind the logo is a magnet sensor that switches off the screen.

Thank you, but I have children. I need to be able to play music, and their moms voice through the car speakers on long drives.
The car I prefer to drive is also noisy and my phone can't always hear me when it is in the dash mount.
What I want is just to make a wired connection to a mic, speakers, and power, through the micro USB port. So I get in the car, plug my phone in, and slide it into a permanent holder.
Money matters and this would be free, also convient since all my stereo did was get music and calls from my phone anyway.
I know how to wire in a Bluetooth reviever for the audio, and a qi charger so that would be wireless but I don't know how to get a mic input back to the phone, none of the premade affordable receivers I have seen have a mic input.
And I am aware I could take audio out and in from the 3.5 jack and either go wireless for the charging or have to plug in two cords in I get in the car.
I appreciate your help but I am looking for help to reach a specific solution that will be best for me.

I assumed already that you were looking for a custom and cheap solution, that's why I gave you mine. Just for the possibility you will get an idea.
About the microphone.
Wired headsets with earphones and microphone are normally connected to the 3,5-jack.
I think the mic-input-connector is there and not in the USB connector of the N6.
The N6 is not that different compared with other smartphones.
There are adapters available Google '3,5 inch headset adapter'

You are right in that there are dedicated connections already at the jack, and that they would be easy to just splice leads onto a standard wired headset to extend to where I want the leads to go. Even if i need to add a signal booster to the mic line.
My wife has a usb headset that works fine with my phone though so I know the capability is there, as with audio out on a usb connection to a stereo.
She wont let me cut up her headset to see what goes where though and it takes a while to get one from china. I was hoping someone knew so I could use what I have on hand rather than spending anything, I am cheap.
Thanks for your help, i have used my phone for music and handsfree when it's just me in the car on short hops. It does work fine for that and as a portable music player anywhere not to loud without any problems.
Once again thank you.
