how to enable microphone while

is there any way to enable build-in microphone while using 2.5mm audio jack connected to car's stereo?any registry edit?Thanks in advance!

I think that the insertion of a jack into the socket operates a hardware switch so I don't think there can be any software tweaks. It is the same as plugging headphones in to a radio etc. the insertion of the jack breaks the connection to the speakers and diverts the output to the headphones.
I got a 2.5mm 4pole male to 3.5mm 3pole female adapter with built in mic and volume control off ebay for less than £5. A cheap 3.5mm patch lead to car stereo later and it works perfectly, other than a slight alternator induced whine is audiable when charging. This is more likely to be from my cheap car charger as it goes when not charging. I like the way MP3s etc get muted when a call comes in. TomTom, Mortplayer and phone calls all at the same time, I love my Wizard.

Guess u didn’t try it. I have my wizard attached with the car stereo and when I get a call i can receive it and talk, the mic gets activated auto. Works perfect for me. Give it a try should work for u.

didn't try what?how does your mic work?

Well I use a 2.5 to 3.5 mm converter which in connected via RC wire to the car stereo linein, when I get a call I just receive it and I can talk. The music stops I can hear the person call and can talk back, the microphone works perfect.

with mine 2.5->3.5 mm jack(done it myself, the 2.5mm jack has 3 poles, not 4) can only hear but the other person doesn,t hear me

my jack has 3 poles, bougth it from ebay some time back, works perfect for me

Car stereo auxiliary jack silent?

I just got a new car that has an auxiliary jack that says I can play my music from MP3/Ipod players. I bought myself a 3.5 mm cord, plugged it into the HD and the Auxiliary port in the car stereo, but there's no sound.
Is there something else I need to do in order to hook my Blackstone up to my car stereo's Auxiliary jack? I figured the 3.5 mm Auxiliary port would just hook up to the HD's headphone jack as if the stereo would act as headphones. Am I wrong?

With mine, I just plugged the 3.5mm jack into the HD and every sound even phone calls automatically came through the cars speakers.
Try plugging another device with a 3.5mm jack into the car, if there is still no sound the theirs either a setting on the head unit or cable may be faulty.
Here is the cable I used, connected directly to the back of the head unit using RCA connectors.

Hmm, does sound (sorry) like a cable problem. I have plugged the HD into external speakers via the 3.5 socket with no problems.
What you are aiming for should work but the cable needs to be right.

You probably have to go to the option on your car stereo. It's just like changing from the fm receiver to the cd player on your car stereo (except you have to go to aux-in).
Look in the car stereo manual how to activate the aux-in option.
If Headsets work fine on your HD this should work as well.
Then it's not a problem with you phone.

Thanks for the replies, everyone. I did switch it to the "Aux" function as opposed to Radio/Satellite/CD/Etc., so I'll see if my son's iPod Touch works or maybe there's something else I have to do with the stereo in the user manual. Otherwise I'll assume the cable is faulty. Hope my wife didn't throw out the packaging just yet! It was just a cheap $7 retractable one I got from Target. Next option is a 3 foot $15 one.

Also, make sure you connected the cable to the aux-in on the stereo and not the aux-out. This isn't always indicated in a clear way (I'm just thinking what it could be).

Yep, thanks for the input. Luckily it's pretty idiot-proof. It's the manufacturer installed Bose stereo system in a 2009 Nissan Rogue. There's only one input on the front face of the stereo panel labeled "Aux In". And you press a button labeled "AUX" to use it as far as I know. Pretty handy!

i have the same problem with my Alpine stereo,has an AUX Input,Even when i enable aux on the head unit still no sound.Taken it to my local car audio garage and theyre baffled!
Later said to me it could be a faulty HU

Ah, well I am used to after market stereo's with the connections on the back (rca connection).
Sorry that I'm not able to help. Well as long as you get sound through headsets and such it is not a problem with the HD, but I guess you figured that out.

Sadly those RCA's are usually outputs for an amp :'(

I'll test my son's iPod Touch today with the cord and see if his works. If his doesn't work also then I'll try a different 3.5 mm to 3.5 mm cord. If THAT doesn't work then I'll have to assume the stereo is malfunctioning.
Another thing that crossed my mind is what if the headphone jack on the HD doesn't produce enough juice to feed into the stereo. Would that be possible? Although it sounds like others are able to get theirs to work, so I'm assuming the HD puts out enough.
Thanks again for the quick input, everybody!

when you plug the lead into the touchHD, you do get the liitle headfones show up on the topbar of the screen?
you havent muted the media player somehow?
you have removed the 100dB eurolimit on the HD output yes?
vol on the HD is around the 80% on both media player and general system sound?
AUX is actually enabled on the headunit in the car? on my factory fitted headunit, the aux button is switchable between the aux line in and an external cd player... if you have the manual for the headunit, have a look to see if there is this option
the headfone jack on the HD pushes out plenty of power, especially if the 100dB limit is removed (hd tweak or advance config... dont forget to disable audio booster and the EQ as that will really mess up the sound)

keep built-in mic active when 3.5 mm jack is plugged

Hi everyone,
I'm wondering if it's possible to have built-in mic active when a cable is plugged into the 3.5 mmjack. For example...I connect the hd2 to the car stereo and if I get a call i need to disconnect the cable because the built-in mic is inactive.

Mine works when I plug mine into my car with a standard 3.5mm stereo cable.
Does the cable you're using have 1 or 2 black stripes on the plug?

i agree, this feature was one of the most pleasant surprises for me with the HD2.
on my kaiser, i used a special HTC headset that had an inline microphone (which i snapped on to my shirt collar) and this headset allowed me to plug in a standard 3.5mm stereo jack, which my car audio was plugged in to. this was the best solution at the time for the kaiser that allowed me to keep all cables connected and be able to use the car's speakers and have a working microphone all at once.
but with the HD2...WOW!!! i plugged in my car stereo's 3.5mm stereo jack straight into the HD2 and put on some music and started driving. a call came in while driving and i just pressed answer because i was still used to my kaiser set up (i had owned the HD2 for less than 24 hours at this point so wasn't quite used to it yet).
i started hearing the other party and i started speaking. and the other party could hear me. and THEN it hit me...i was like, holy hell!!!...what am i speaking in to? how come the other party can hear me?
great features, great phone!

I think it has two stripes since it's a stereo jack. I'm not sure but i think initialy I was able to speak in the car with the leo plugged into the stereo. May be some app I've installed later changed something?!?

the built in mic will stay active unless u have a cable with 4 connections (3 rings on the plug), a regular stereo cable has 2 rings. I've been using this type of setup for a couple of years with my previous phone, a.k.a. iphone. The mic is pretty sensitive and can pick up your voice rather well. I have my hd2 clipped to my sunvisor for easy access and routed the wiring inside the windshield molding down under the dashboard to the stereo and it works pretty good.

Headphone Jack Issue

I am interested in purchasing this phone, but I read there is an issue with not being able to use the microphone while headphones are plugged in. I hook my current Android into my car stereo through my headphone jack and when people call, it uses the speaker phone to talk while I hear people on the car stereo. Would I still be able to do this on the Fascinate, or does that also disable the speaker phone mic, or are they the same mic?

im not sure what you are asking but i ahve no problems with it, i plug in my headphones with the mic in them and they work great, use them for listening to music and talking and love it

He means he has his phone plugged into the speakers in his car through the aux jack, and then when he gets a call he uses the speakerphone option to talk, and incoming voice audio plays on his car stereo. I do not think this will currently work on the fascinate...

You've heard right. It blocks speakerphone when headphones/aux are plugged in. It's quite a pain considering I use it as my music player in the car. It also ignores bluetooth while plugged in as well.
I got used to unplugging it when I get a call, though.

This is correct, and was almost a deal breaker for me. However, the car dock has a function where you don't need to plug in the AUX, only the micro-USB, and you can charge it as well as have audio output (the audio goes through the charging port, then is output by a 3.5mm output on the dock, and finally to your car's AUX in). This feature isn't enabled yet, but once Froyo is released it will be - and then we should be able to take calls over our car speakers without the mic being muted.
Just something to keep in mind,

So Indy, we can't use the car dock the way it was intended until froyo drops? That means I can't hear my nav thru the speakers while docked or any music?
Sent from my Fascinate

As I understand it, yes. There is a sticker on the port letting you know that it won't function properly until the release of 2.2. I'm still waiting on my dock to get here in the mail, but I've seen several threads elsewhere where this is discussed.
I don't think the dock has room, but if it does, you could still run an AUX cable from the headphone jack to your car's input, and have nav and music through the speakers - you just wouldn't be able to take calls with it connected because of the mic being muted with an AUX cable connected. Once 2.2 is released, as I understand, you'll be able to do it all.

Thanks for the help. It looks like ill be waiting before I make a purchase. I use slacker radio too much in my car and my deck doesn't have an auxiliary in, its old school tape deck so I have a device that plugs in the tape deck.

[Q] Broken Headphone Jack

Hi,
I mistakenly plugged a powered cable into my headphone jack. I was in my car, it was dark; I meant to grab the audio cable so that could connect my phone to the car stereo. Instead, I grabbed the power cord to a backup display and inserted it into my HD2. The phone is fine, but I now get very little sound out of the headphone jack. I was wondering if there is a fuse on the jack that guards against power input and if so, can this fuse be replaced? Does anyone know if this is possible? If not, I guess I will need to get a Bluetooth headset in order to listen to music and movies again.
Thanks for your help,
Paul
