Connecting phone to a car stereo

Hi all
I have a MDA compact which I wish to connect to my car stereo as a handsfree unit. I have an auxiliary input for my stereo.
Is it possible just to purchase a 2.5 to 3.5mm lead for this? I have a gut feeling the mic won't work - please help? Is it possible to buy such a lead with a built in mic?
Thanks
Carl

Hi, I used to have a XDAII which I connected to the auxillary port on my car stereo, just like you suggest. It worked perfectly. When using the phone, the caller's voice woudl come out of the car speakers and the mic was powerful enough to pick up my voice even though the unit was mounted on my windscreen.
Unfortuntely, both the Wizard and the Exec automatically disable the mic when you plug into the headphone socket. Not sure about the MDA comact. Sorry couldn't offer more advice on your particular device, but I hope my experiences help.

I do have the same setup. I can confirm U the mic still work after U plug in the adapter but I normally use a BT headset when I am in the car.

OK, so I assume that if I purchase a 2.5mm to 3.5mm lead, the mic should work?

Yes. 8)

OK - did some work on this.
I decided to cut the earplugs off of the supplied headset, and attach a 3.5mm socket.
I now have a custom XDA mini lead
All works, however volume from car stereo speakers is extremely low. Any ideas? (Yes, I have checked car volume, phone volume and headphone volume!)
Cheers
Carl

Hi Jackleung, my mic is being diabled, and i am beginning to think that I may not have the right connector. I have a standard 3.5mm connecting the exec. Can you let me know how you have wired your device with the type of connector? You may be able to solve a longstanding problem of mine.
Thanks in advance.

I found my mic was cancelled with the Mini, hence the custom cable.
hope this helps!

I think my adapter is just a standard 2.5mm to 3.5mm converter. I tried 2 different adapter (one from Radio shack and the other one from ebay: http://cgi.ebay.com/USB-CABLE-headp...ryZ15040QQssPageNameZWD1VQQrdZ1QQcmdZViewItem)
Both are working for me (I will try again today and confirm U tomorrow), therefore I think yr problem is in the exec hardware itself.
To Carl,
Yr setup will not work since yr supplied headset adapter has at least 4 connection on the plug compare to 3 on the standard one. The extra connection is for the mic. If U cut the wire like this:
<---- X --- mic+volumn control ------ ear plugs
Then U can no longer use the mic w/ the custom wire. But if U:
<------- mic+volumn control -- X ---- ear plugs
then the mic on yr mic+volumn control will pick up the voice

hi jackleung
Thanks for the reply - the lead was cut after the mic but before the earphones.
This was because a standard lead with a 2.5 / 3.5mm adaptor didnt work.
My only issue now is the low volume!
Cheers
Carl

I tried it on my Imate Jam again. My mic on the Jam still works (eg: Voice Command via Cyberon Voice Dial. So do phone conversation) even I use my 2.5mm/3.5mm adapter to connection it to my car stereo.

Hi,
I did the same for me and a friend of mine with a Univer..er - Jasjar and connected this to an FM transmitter - We have excellent sound quality, volume and the you can still answer calls by pressing the Mic Button

(If you are gonna be late - dont rush, else someone else and YOU will be cross)

check connections?
I have done exactly what you did, put a 3.5mm socket on the end of the included handsfree cable.. volume is fine, and i regularly connect it to the aux in the car, and multiple sets of headphone/speakers...
The best suggestion to your volume problem is to try again.. i know i had issue with the stereo channels getting screwed up (and even combined at one point) and it was just trial and error getting the connections clean..
You have to ensure that both the shaft and tip connectors on the socket are grounded to the shared ground on the circuit board.. otherwise the audio will probably be less than perfect.. check for dodgy soldering/connection.. coz i can assure you that your theory does work!

There is another topic on this here.
The person from there uses:
http://www.expansys-usa.com/product.asp?code=PPCPADPT02
which has two 3.5mm plugs.
Description: It has a 2.5mm plug at one end (this plugs into the PocketPC) and two 3.5mm sockets at the other end (into which you plug your 3.5mm headset or headphones).
My question was: could I put a standard 3.5 car kit mic into this 3.5 headset jack (the one with the mic)? Would the mic work if I plug it into a headset jack?
I assume the other one (headphones = stereo only) I will plug it directly into my car auxiliary via a 3.5mm to RCA cable, right?

wired headset?

Hi chaps,
Do you have any suggestion for a wired compact headset to take phone calls?
I got a bt but its not always on and when I get a call, I dont want everybody around me to hear the conversation but when i pop in a 3.5mm stereo headphone, the microphone stops working
I cant find a combo in-ear headphone microphone thingi with one 3.5mm jack or a mini usb headset... so any suggestions?

What about the original one in the package?
You can leave your device in the pocket and accept or quit phonecalls.
You can set the volume of the incoming call to lowest with the slider left to the navi-stick, then other people do not hear your calls if you are 2-3 meters away.
I'd like to know a wired headset which shows the caller-ID in the microphone case, like the old sony walkman with the display on the wire, showing actual song and volume. The 3.5 jack will not support this, i know.

yeah you can just leave any 3.5mm headphones pluggged in, as long as they are plugged in before the phone comes in you can use the inbuit microphone.
The device still rings, so you just put the buds in your ears and answer.
This is what I do with my senseinhers.
I'd like a decent replacement corded set, don't like the sound quality from BT ones I've tried.
Had a USB one from gpsforless that you can plug your own headphones in just past the mic, but it wasn't well built and lasted about 3 weeks.

I bought this one for use in the car while plugged into my AUX in on the car stereo.

It works great with the Athena, there are a bunch of different types on ebay, just search for "Tytn Adapter" and you will find a bunch.
Pretty much any HTC Extended USB based adapter will work with the Athena.
Good Luck

thanks for the advice; i bought it second hand and didnt get the original one. does that one have a mike?

I don't have such a problem with the original wired headset. The sound is excellent in both WM5 and WM6.

My wired headphones died pretty quickly, so now I use a pair of sennseisher buds, the microphone on the athena works when using standard earbuds, so although not hands free, it is at least a bit more private.

I like this from PPC Techs.
http://www.pocketpctechs.com/main.asp?unit=HTC_Advantage-895&area=accessories&item=PPCPADPT17
It gives you both 2.5mm and 3.5mm output so you can have your headphones in one plug and the headset in the other.
They have another adapter that goes from the USB for the same purpose but I don't have that one.

VX6800 to mp3 speakers

Wow I thought this would be easy.. I have a VX6800 Verizon that I enjoy listening to indie 103.1 indie stream through TCPMP except the speaker blows. I thought I would get a usb to mini headset adaptor so I could plug into my mps player speakers, but the adaptor I got from Radio Shack dosen't seem to work? Do I have to change some setting or something to get the audio to go out through the USB jack?
TIA,
Chris

You have a better chance using the Bluetooth speaker set. You get better quality "stereo" and you can increase the volume way louder.
Also try searching for the SRSWOWHD CAB. This enhances the volume in your phone with some modifications in the program.

The adaptor you got from radio shack probably is not wired correctly for the type of connection on the phone, even though it physically fits there it is kind of a propietary connection and has extra pins that are not standard. Many of the phone accesory websites have the correct one. Here is a link to one that works in our phone http://www.elitextreme.com/3stauadforht3.html

jjlwork is right, our phone has 11 pins where typical miniusbs have 10. You wont get it to work right, or you will mess up your phone.
Try this too, I have an extra in case my other breaks cause I use it in my car. I will have a writeup in accessories later today.

Should check... there is some change in 3.35 that causes some of the
audio connetors to not work. Happened on mine. The oem headset does
continue to work.

Anyone using their Titan as an MP3 player in the car?

I found out I can put rhapsody tracks on the SD card on my Titan (XV6800) so I've been using it as my car MP3 player. Problem is when it's plugged into the charger I get some noise (the phone is connected to my car using an aux port.) My question is does anyone use a similar setup, and if so what do you use as your charger? Right now I'm using a cig port to USB thing. I could probably reroute the ground, but I'd rather not deal with the mess of wires.

is this capable?

?? Are you asking how I have my phone as my MP3 player?
You need something like this. I have that connected to the 2.5mm/USB splitter that comes with the phone, then there's a 3.5mm lead that goes from that connector to my car stereo's aux input.
Considering there's a mic on the adapter, it doubles as a handsfree kit so when a call comes in, the music pauses and I can hear the caller through my stereo.

Pioneer Avic D3
I have the Pioneer Avic D3x in my car with the bluetooth module. I just installed it. I had to install a plugin on the mogul called a Jet something and it connected fine with my audio in the car. I can listen to my radio station SuperRadioMix.com and it mutes out when someone calls. The station streams perfectly to my mogul phone. This may sound like a advertising for my radio station....and it is. . Just to let you know you can do it.

Oh yea, blutooth would solve the problem because it's most likely related to the common ground, however I already have a rather nice Eclipse head, so I'm not looking to replace it. I am looking around for blutooth adapters though.

That noise you're hearing is a ground loop. The only way to get rid of it is to use some kind of ground loop noise isolator, like this one:

I use Mortplayer on my Titan for MP3's as well as streaming radio. It works really good!

This is exactly what I'm using. You can find it on Verizon's site, you might also be able to find it in the store.
Thanks coodaddy1, I figured that was the next step. I thought about running a ground from the cig lighter to the chassis to see if it eliminated the hum.

I am using the usb/2.5 splitter that came with the phone with a 2.5-3.5 splitter i got a radio shack, all that connected to my stereo line in. Works like a charm.

I found that the 2.5-3.5 doesn't have the correct amount of posts and you will need to eventually pull out the tip to get full stereo (are you sure you are getting stereo sound rather than mono out of both speakers- all left or all right)?
If that works, cool!

This is what you need - Car Dock with Audio out

NICE
I have ordered from these guys before - very high quality

I use mine for that all the time. I have one of those bracketron mounting clips that clip to your vent and I use the included headphone adapter and the usb splitter (becuase it wont charge unless you connect the power to the usb splitter). I connect a mini usb cable to a usb adapter in the charger socket. To connect to the radio on my ford focus I have a digital adapter that lets me use standard rca jack input to the digital port on the back of the factory radio (works with any any audio source)
To connect to the 2.5mm headset adapter,I have a cable I made by chopping the end of a old 2.5mm handsfree headset and soldering a standard 3.5mm headset socket to it. You should be able to buy a similar adapter from any vendor on the web. The headset that the moguls included adapter wants is the standard four conductor one that most multimedia cell phones like the samsung a920 use. (I originally used the cable I made with a samsung) The only problems I have had is that vibration from driving sometimes jiggles the mini usb loose from the phone and you have to plug it in again. I guess I could route the cable over the top of the bracket to hold it in place to solve the problem,in fact,Ill try that tomorrow.
One other problem I have had is tomtom as it has no internal media player. I was using it for gps functionality,but other than the fact that it is missing all sorts of key information on my area,like points of interest that it really should have,its very difficult to switch out of it and control media player. That means that while you can start your music and then launch the gps program you are then stuck with whatever your play list is and cant control media player. Other than that it does work well and the voice comes through fine. I switched to Garmins gps software and it works great. It does not even need to have some other app initialize the gps like tomtom does. It does not have an internal media player either,but at least its a little easier to switch out of.

im running a bt headset with a miniplug straight into my aux input in my car. works well enough to stream music and mp3s

[Resolved] Question re car stereo, aux and bluetooth

I have a feeling that this can't be done (because I looked into it with my XDA Exec a few years ago), but....
Is there any way that I can play mp3s via the extUSB into a car stereo (via an AUX in) and yet answer calls via the same stereo's integrated bluetooth via the headset profile?
The stereo would normally drop the AUX in sound for a bluetooth call, but clearly the extUSB would normally handle calls if a audio output device is plugged into it. With my Exec, I seem to remember that the hardwired audio output would be the default, and so the bluetooth would never engage.
If there is a hardware solution, I would be very keen to know! Even better if the extUSB also charged my Vario IV in a passive holder.

What about playing music through the blue tooth of your car stereo? Tricking the car into thinking its actually engaged in a call so it plays music. Might have to be something done on the phone side to transmit the music as a call and then when you receive a call the music stops and you can answer the call and when the call ends music resumes? Just a thought i dont know if it is possible at all. But you bring up a really good idea.

Thanks for the thought, but the stereo doesn't accept bluetooth streams - it simply just has the ability to act as a hands free device.
Any more thoughts anyone? (Although someone has just posted about a device that looks intriguing with AUX and power in)

It's definitely doable. Thats what I've done with my non BT Pioneer deck. Check out my post here - http://forum.xda-developers.com/showthread.php?p=3278241#post3278241.

Thank you too for the feedback, but I can't see a bluetooth device in your chain. Perhaps I wasn't clear in the original post, but in the end I suppose the question is can calls be handled over bluetooth when there is any audio outpu device plugged into the extUSB?

Sorry. My bad. You are right, I did misread your post.

the answer is yes. that is what i do daily.
i listen to music through quality wired headphones, and when a call comes in i use my bt headset WITHOUT unplugging the headphones from extUSB.
all you need to do is answer the call using the answer button on your bt headset and not your phone.
in some phones, if you will press the send key on the phone and not the bt headset, the call will transfer to the phone instead of the bt headset.
hope i was able to help.

Thank you.
Do you think it matters that you're using headphones rather than a headset? I'm just wondering, since you refer to headphones, if the lack of speaker in your wired device means the call will hand over to the BT device - this will allow me to work out what I need to buy.

hmm i think since your aux input wont really have a mic attached it should hand over the call to the bluetooth headset from what the other person is saying.

Hi, I don't know if this will apply to your stereo setup but I thought I would let you know my setup anyway.
I use the HTC multifunction audio cable http://www.expansys.com/p.aspx?i=171925 which lets me charge my phone via a car charger and use the 3.5mm audio output to the stereos aux input at the same time - all of which are in center armrest compartment.
I use bluetooth connection to the factory installed bluetooth prep (BMW 3-Series). When a call comes in the TP pauses the audio and the BT phone then takes over. When the call ends the TP un-pauses the audio

I just installed a Blaupunkt MP57 on Sunday and did exactly what you're describing. Phone connected via aux playing music, answer or make calls via bluetooth on the stereo and the music pauses then restarts when the call is ended.

Both can send all outgoing audio from your WM device via BT headset channel instead of A2DP. It's not advanced audio but it will let you play audio over the headset BT channel. Sound can be tweaked using SRS WOW HD.
ExtUSB is just a port which will enable playing MP3 tracks on for example USB drive? Why not put your connection in USB mode then?

I'm not sure if this will help you, but I bought a Motorola Bluetooth Car Kit. I don't have the "phone" feature built into my car Stereo, so I used the external amplified speaker and mic for "phone" functions. The Car Kit has an Aux Out, with I feed into my car stereo. When I get into the car, the Bluetooth initiates two separate "connections". One for the "phone" and one for the "MP3 Player". You can have either one or both. The music plays through the car stereo (via the Aux Input) and phone calls play the the external Car Kit Speaker. It is like having two independent bluetooth "channels". When I have Voice Commander enabled, it communicates through the "phone" channel, i.e., the Car Kit mic and external speaker. That is also where my incoming email is announced through. My Garmin GPS "speaks" through the Aux out and the Car Stereo though. I'm not sure how these routes are selected. Personally, I would prefer that the GPS also communicated through the "phone" channel, that way if I am listening to the Radio, or Sirius, or a CD (not on AUX-IN), I would still here the GPS voice guidance. I'm not sure if that can be changed or not.
Hope this helps.

I do this all the time. USB to 3.5mm stereo to Pioneer head unit and calls come in over the BT

Thanks all for the input.
Just bought a Brando adaptor:
http://www.inkino.co.uk/zen/index.php?main_page=product_info&cPath=126&products_id=1502
Tested it and Copilot and Music run from the Aux out. Bluetooth hand over perfectly. As an aside, I find WMP is a better MP3 player, simply because I can reduce the volume in the software, but leave Copilot to use the system volume at a slightly higher level so the voice doesn't get lost (the HTC player doesn't seem to have the same capability).
Could have bought the HTC branded device from the same place, but the main lead from the Ext USB is slightly longer and more inflexible so wouldn't easily fit under my car holder.
BTW, since I live close to the shop (plus I love instant gratification as opposed to mail order), I visited the Inkino shop in London. I must say that the staff were very knowledgeable and helpful and the shop has a huge range of HTC accessories (including a branded battery and extended battery for my Universal, which I am planning to resurrect). Not sure about the prices vs ebay, but for the bricks and mortar approach in the UK, where it is difficult to find anything HTC - 1st class!
