Can anyone help me with this:
I have always used my PPC's in my car connected to an external audio jack via a 3.5mm headphone connection. Not only did I use this for music, but it also allowed me use my car stereo to hear my callers much louder than the speakerphone was capable and still let me to use the built-in mic of the PPC to talk back.
Enter my Artemis and it's proprietary mini-usb audio jack...
I purchased the HTC mini-usb to 3.5mm adapter from expansys so that I could continue to use my in-car 3.5mm connection. Works great for music and TomTom (Austin Powers is scary loud now when he tells me to turn left!) BUT the built-in microphone in the Artemis seems to be disabled whenever the adapter is inserted in the mini-usb jack! I can't use Voicecommand with it inserted and my callers can't hear me until I pull out the adapter - which then takes away my nice loud car stereo to hear them!!!
Presumably, the disabling of the mic is because the mic in the included headset is expected to be used for calls when the audio jack is occupied. I know my configuration is not "standard," but it works (or worked) great for me and I would love to be able to continue to operate this way.
My question is: can anyone tell me which registry values control when the built-in mic is disabled? There must be a value that tells the Artemis to shut off the built-in mic when the headset is plugged in. I would love to change this so that the configuration I described above will work for me again. I have some trepidation about tinkering with my registry too much when I don't have that much experience with it. I hope there is some registry guru out there that will take pity on me and take on this challenge (if it's even possible).
Thanks in advance!
You'll have problems with something like this... I'd assume that it'll work similarly to the headset antenna registry entry, where on connection of the headset a key relating to the FM Radio software is changed from a 0 to a 1 allowing the application to launch.
There are one of 2 outcomes for you though unless you want to get crafty with a button or something to make the changes for you....
1 - Although you'll be able to change the reg setting, plugin in the usb cable or disconnecting it will simply reset the key,
2 - You'll permanently change it and if you want to use anything other than the handset mic you'll need to undo the change.
I'd say more than likely if it a dymanic key though and triggered by connection or disconnection of the usb cable then option 1 will take effect. I'm guessing that you'll need a button (software or hardware assigned) to control this properly.
Good Luck!
I'm too lazy to read.
Check the state and notification broker. Otherwise you'll probably have to directly interface with the audio driver.

Me too...?
Hi all,
I too want this fix, using the microphone whilst drawing off the audio feed for my vehicle stereo. Can it not be done with a soldering iron & external mic wired into the dongle adaptor?
Thanks Paul

Here is an adapter with microphone...
I suggest hacking a handsfree and making your own jack for the car. this is my plan soon!
Hi All,
I have the same problem with my HTC Diamond. Did anyone have a fix for this yet? As i do not mind changing the registry or if someone wanted to make a little program that would do this i would be more then happy to donate for all your troubles.. I'm unable to hack my fm transmitter as it is a holder aswell... see picture
Anyone with a concrete solution?
This seems to be a hot topic! Are we really sure that adapters with mic are not readily available?
If you're au fait with hardware hacking, haret can probably tell you which interrupts are being used and you can write a solution to poll the irqs that way.

There is nothing to do with Registry Hacking or Softwares in your case...

There is so many ways of soldering of wires (Line IN & Line OUT) using a mini usb to made your PDA more compact...
The built-in microphone in the Artemis or Any other HTC Devices sure have to be disabled whenever the adapter is inserted in the mini-usb jack for the soldering of 2 Line-Out (Audio-Out Left & Right) and 1 Line-In (Audio-In/Microphone) Example: Headset that come with your PDA.
Unless HTC going to make one mini-usb to two cables,one for 3.5mm adapter for headphone and another to Mic.jack or a Microphone itself.
This is quite difficult for HTC to custom a cable or jack for individual need.
I think you have to DIY for your need in this case:
Use the headset that come with your Artemis, the one that have a Mic and mini-usb jack...
Cut away the left & right earphone, soldering the two cables into a 3.5 jack (male or female)
Both this jacks-Male or Female can be found in electronic spare-part shop anywhere.

Hi,
I was just wondering if anyone has a car stereo with bluetooth capabilities. I have been looking at getting one myself. For the longest time I used a treo 650 and had an FM transmitter hooked up to the audio port so I could hear my music and GPS programs over the stereo. Since the Touch only has the mini USB out and I have yet to find a fm transmitter that uses this interface I've basically been stuck using the rear speaker on the phone.
I have seen a bunch of car stereos that are bluetooth capable. I realize that they have to be able to play streaming music via bluetooth and not just handsfree to get the full "stereo effect". My question.... Has anyone tried this out or knows anyone that has used it. Also, how would hands free actually work via the stereo?
Thanks!
Aaron
hmmm..why not just get a bluetooth receiver with a 3.5mm jack. I'm currently using the itech bluetooth clip radio and am able to output stereo music from my touch to my speakers. It also doubles as my handsfree when i'm out and about.
As you mentioned you're using an FM transmitter hooked up to the audio port of your car speakers, this would be something very similar to your existing setup and probably a lot cheaper than getting those bluetooth speakers you mentioned
I needed to replace my car stereo as it is because the display didnt work. Just figured I would upgrade and get one that had bluetooth capabilities but it would seem either no one has tried to play music through a deck with bluetooth capalities here OR that not one has read the thread. Either way I think I'll at least spend the cash and see what happens. Wost comes to worse I just bring it back
Also.. I was going for the whole LESS wires thing.. Having a bluetooth reciever with a 3.5 mm jack that goes to an fm transmitter just.. yeah thats alot of clutter. I'd like to have it where the touch is mounter to the dash (as it is now) and all I need to do is push a button on the car stereo deck and the sound is routed though there. Having the phone plugged in is one thing but then having an fm transmitter and a bluetooth reciever and what not all over the dash is just a pain in the ass I think.
im using the sony/Erikson mbr-100 bluetooth stereo receiver with 3.5 jack. works great.

Is there anything specific I should be looking for. Just.. basically that it can played streemed music and not just hands free correct? That way ALL of the audio will play through the stereo.. not just the phone calls

The magic phrase you're looking for is A2DP. That's the Bluetooth protocol for streaming music from one device to another.
I got a Parrot MK6100 for Christmas, which is a dedicated hands-free kit that plugs into the back of the OEM head unit in my '99 Audi. The MK6100 is both a hands-free for the phone and a streaming music player for the phone too. It's excellent so your proposed solution might be perfect for you if your new head unit delivers the same functionality as this Parrot.
ALL the audio from my Touch is delivered through the car's speakers, including screen taps, TomTom directions, music and so on. There are some caveats though, caused by the Touch rather than the Parrot, I think:
Although the phone functionality works perfectly (it's actually very impressive - I just get in the car and it works straight away) playing music is more complex. I have to reconnect the phone's A2DP output to the car kit before I start the HTC Audio Manager, and I have to exit the Audio Manager before shutting down the car kit, otherwise it crashes and requires a soft reset for the Touch before it'll work again. I think WMP is more reliable but it doesn't integrate into the HTC Cube or HTC Home utilities so it's not a desirable solution for me.
I recommend you test the bluetooth streaming functionality with your Touch and the head unit before you buy the head unit if you can - you might find an incompatibility.

Sorry just saw this post was updated..anyway the clip radio does have A2DP and AVRCP support. Also, there is no need to use the FM transmitter. I mentioned similar..not use existing
but yes there will be a wire going from your speakers into the 3.5mm jack of the bluetooth receiver. If you want it completely wireless, then you will need speakers that have a built in bluetooth receiver..not sure where you can get one though..

I also have a question about htc touch and my head unit Alpine IDA X001.
I'm thinking to buy the Alpine bluetooth adaptater KCE-300BT which works with the head unit i have.
With this adaptater the head unit can display your last calls and let your browse in the phonebook.
Do you think that it will work with the HTC Touch (Windows Mobile 6) I have ??
Thanks
Here are the specs of the BT adaptater of Alpine :
SECTION BLUETOOTH
Version Bluetooth Bluetooth 1,1 CERTIFIÉE
Puissance de sortie +4 dBm Max. (Power class 2)
Profil HFP (Profil mains libres)
HSP (Profil casque téléphonique)
A2DP (Profil de distribution audio avancée)
AVRCP (Profil de télécommande audio/vidéo)
I have the SONY MEX BT2500 CD MP3 CAR STEREO that I had for Christmas and fitted myself. I am really impressed with this unit and it works really well, it also works as a bluetooth hands free.

Hello there,
I have Blaupunkt Hamburg MP68 and the bluetooth on it is excelent. Both handsfree & streaming working fine.
I have bought a Blaupunkt Hamburg MP68 stereo. I am very satisfied by this unit, it is a very complex device and it provides even a built-in bluetooth car-kit.
However there is an issue that I cannot work out: I can't get the stereo to download the phonebook from my HTC HD2 phone.
Both stereo and phone support the PBAP profile (phone book access), but the I always get the message "DOWNLOAD FAILED" on the stereo.
I have noticed that the "Dev A" profile (serial port) from phone's Bluetooth menu has a configuration option named "Local COM port", which was automatically set to COM2. Among the options, there is one called "ActiveSync" (as seen in the attached screenshot). I think that this might be the solution. Can anyone confirm my theory? I can't get to the car sooner than 4 hours from now.....
May be worth posting this in the HD2 forums as well. it has a much newer os with newer features then the touch does, by some 3 years. I do realise that this thread may be related, but people in the HD2 section may be more aware with any bluetooth features specific to the phone as well.
No need to do it, but thanks for the tip. 10 minutes ago I have tested the "ActiveSync" port setting and it works fine: all phone contacts are downloaded into the car stereo.
Cheers!
Grats for doing it then
I am pretty new to Android and still trying to get all the grips on I need. As of now, there is one thing that really bugs me badly.
I use the device for Sat-Nav driving a lot, I have a semipermanent installetion in my car from my previous smartphones. Basically just a power feed and a 3,5mm Jack that come out of the dash panel where the device holder is mounted. I recharge plug in for recharge as needed. The audio jack goes into the device, from there to a so-called Fastmute box behind the dash which is connected to the stereo head unit (the loudspeaker output cables running away from the head unit to be specific. The Speaker lines are interrupted by the box and just pass through whatever audio is being played back by the stereo. However, once there is current on the 3,5 audio jack (i.e. speech from the SatNav) the music immediately goes mute and you can hear the turn instructions in perfect quality through the car speakers. Once the signal fromthe satnav dies down stereo music comes back.
For my taste this beats most commercial, fixed systems.
Now, since I am on Android weird stuff happens.
On a first testrun shortly after I gut the Desire (which was o2 branded stock 2.1 at that point) I noticed that I do not get any announcements through the fastmute. Checked the jack, opened the dash to check internal wiring, retried a mp3 player. It's all good on that side. The accouncements come through the device speaker, hard to hear, easy to miss a turn etc. I do not why or how, but it seems that the audio routing takes a route different from other audio. This had me pretty much meh!
Well few days later, now with a ModaCo R8 custom ROM and Froyo I was hoping for good luck and gave it another whirl. Of course, no dice. When I plug in the jack of the supplied headset (which I assume doubles as a handsfree) I get the symbol for that in the upper symbol bar. When I exchange that headset jack with the regular 3,5mm jack the symbol looks different, but still vaguel like a set of speakers.
But now here comes the completion of the mindfaq... I had the SatNav volume at about medium (so barely hearble with driving ambient noise) when the phone went and I took the call through the Bluetooth Handsfree instaalled in my car and was distracted by the call (the car came euipped with the BT Handsfree from factory, so the stereo goes to "pause" and the conversation is routed into the vehicle speakers.. A few minutes into the call I suddenly hear a perfectly well understandable, clear turn instruction hopping into the phone conservation. I was extremely intrigued and was hoping that I discovered that CoPilot can route instructions either into A2DP or more likely emulate a "call event" that results in routing the audio into the according BT profile.
However, after that singularity I tried reproducing this for a god part of an hour, driving a route that forces many instructions from the SatNav, all the while calling my own answering machine fo have an connection established.
Sorry for the lengty explanation. Questions:
1 Has anyone ran into this before? What was your solution? Bear with it, switch SatNav software, avoid listening to music in oder to not miss any turn directions?
2. Is there a hack, hidden configuration that would enable me to _force_ this audio routint into the direction of the BT Handsfree, making it think it is an incoming call?
As a fellow co-pilot user I share your frustration.
You will probably find that it's nothing as technical as it not routing to bluetooth or whatever.
Co-pilot has a nasty habit of messing with it's own volume setting when a headset is plugged in. It tends to reduce itself down to zero without notification or cause. You would try to reset the volume, but firstly, it wont go more than a third of the way up, and secondly, it will simply jump back down to zero again on it's own.
They know about this issue and their response is not to use it with a headphone jack!
It is rather annoying!!
I looked around for a post, but didn't find one.
As I understand it, when receiving an incoming call, you have to
slide up the screen, then click the slender "accept" button (and
then click the little down arrows, then click speakerphone if you're
in a car without bluetooth).
Is that really the best/only way to do it? Anyone working on an
app that makes answering calls just hitting the search button or
something?
As of now, I find it very distracting/dangerous to answer calls while
driving.
Tips?
Sorry but I also would like to know how to terminate a phone call without looking at the screen
At the moment I'm turning the screen on, and then click on 'terminate the phone call'
But I'm sure there is an easier way, especially using the physical buttons.
Thanks for any tip.
if you have bluetooth hooked up to your phone, you can just answer the phone call via the bluetooth device.
Bluetooth is the only hands-free way, I'm thinking they weren't trying to make it particularly easy to use while driving, in many places this is illegal, in the US it's happening more places all the time.
Some places are even attacking Bluetooth usage while driving.

Agreed, and wish MS would also include rSAP as many luxury European vehicles (Mercedes, VW Group including Audi, Bentley, Lamborghini, and other manufacturers/brands) support rSAP, which offers great features such as address book migration to the car for ease of dialing out.

I've heard his protocol is on its way out. My Honda pulls the contacts just fine from my HD7 & 2 and the G1, pulls the exchange data and loads it into the car.

Sad if true as with rSAP the cell phone antenna/receiver that is built into the car is far superior in power than the one inside the phone. What protocol of Bluetooth is your Honda using to pull the data and i assume it pulls the data and uses an antenna/amplifier unit built into your car instead of the cell phones?
TBH you dont really need to look at the screen to answer it, flick up and press in the middle on the left....
But like everyone said just get handsfree, if your car doesnt have it you can buy them stupidly cheap anyway.
On the new MINI its really good, pulls the contacts and all of your text messages from the HD7, you can read any new text messages on the navi screen
I think it was HTC or LG that has an app out there that allows you to do various phone things with the placement of the phone. Like turn on the speakerphone by placing the phone face down after you've answered a call or turning it face down while ringing to silence the ringer...
Yeh the HTC app called attentive phone.

I think it uses Address Book Profile, it's abbreviated as ABP (I'm not 100% sure what is abbreviated there)
It uses the mic and amp in the car for audio, it uses the antenna built into the phone, I've never used the external antenna port on my phones, I think my Tmo Wing was the last one with this port available externally.
For A2DP I'm using a device called FIPO, and a Soundgate core, and a soundgate Honda kit. The Honda kit hooks to the back of my nav unit and pretends to be a CD changer, so that I can use the controls on my steering wheel and nav screen. The Core is connected to the Honda Kit, core comes in two models, iPod and Zune, I used the Zune for my Zune. I use the iPod Core to connect to the FIPO. The FIPO is controlled by the phone, and it switches between that device and the nav unit's Handsfree profile based on wether or not I'm on a call. After I'm finished with my call the phone switches back to the FIPIO and resumes the audio.
Thanks for the detailed reply, as i use the Dice Electronics unit for an iTouch, which like your unit one needs to remove 6-disc changer and insert the Dice unit that hooks to the iTouch. What i like about rSAP is that the car has a far better cellular amp/antenna plus rSAP migrated contacts from the SIM to the car's computer. While i could take out the sim card and insert it into the car directly, that is a hassle versus using bluetooth rSAP for each time i enter/leave the car. The car does work via 'basic' normal Bluetooth with the WP7 for handsfree with all the usual features, yet enjoyed the rSAP advantages. Thanks again, ALL help is ALWAYS apprecaited.
All, as there's a lot of questions coming in to iBOLT's customer service, and on forums about connecting the sound to the car-stereo speakers, using aux-out, playing music while a phone call is coming in etc. I figured we can start a new thread dedicated to all the variables involved. I'll try to make a summary below of functionality. If you have not seen the video or images of this product you can do so on www.ibolt.co/ibpf-33307
First, the iBOLT S III Dock solves the problem reported by many users that when they insert an aux-cable from the headset jack their Bluetooth device does not work properly. Since our Dock takes the Aux-out through the microUSB it works differently and from our testing, and end-user reports, the Bluetooth works fine.
Below is a run down on different options how to connect the Galaxy S3 Dock to car-stereo speakers for playing music and sound from all Apps.
BLUETOOTH OPTIONS: Please note that when using any Bluetooth hands-free device (headset, portable, built-in from car-manufacturer etc) with the Galaxy S3 you can choose if the connected device is to be used for phone calls only, for audio streaming or both. This depends on which Bluetooth profile your device is using. See attached screen shot for an example of the S III UI. This is from a Bluetooth U-connect system used in Chrysler cars (although they should all be the same).
1. Car-stereo systems featuring A2DP:
If your car is equipped with a Bluetooth hands-free system it may allow you to to stream audio (in addition to hands-free functionality) but only if your system features the A2DP (Advance Audio Distribution Profile). If it does have A2DP profile you will have the option during the pairing process to select the "Media Audio" in addition to "Call Audio" (see attached screen shot). If this is the case, the Aux-cable that's included with the Dock will not be used as Audio Streaming over Bluetooth is the preferred choice if your system is set up for it. In this scenario, simply hide the aux-out cable end or tuck in under the car seat or center console.
2. Typical car-stereo/Bluetooth systems:
If your car-stereo does NOT allow you to choose the "Media Audio" this means that your system is designed with the so called "Hands-free Profile", thus it is only able to be used for hands-free calling. For this scenario the aux-out cable from the iBOLT Dock should be plugged in to the 3.5 mm aux-in on the car-stereo, usually located in the center console or in-between the front seats. When you play music (or GPS Navigation sound) from your Dock to the car-stereo speakers and a phone call is made or coming in the Aux sound will automatically mute and start again once the phone call has ended. The sound quality when using the aux-out 9ft cable has been reported to be very good. Some users have indicated that the base is even better when using BT A2DP Audio Streaming, versus aux cable. This sounds very logical.
3. Cars without integrated Bluetooth:
If your car does NOT have a 3.5 mm aux-in jack but features a cassette player there's plenty of "cassette-to-3.5 aux" options to buy. Search at your preferred electronic retailer for the solution that is right for you. Once inserted the iBOLT Dock can be used for playing music through the car stereo as if played through the cassette player but at lower quality.
4. Cars with CD player only, no BT, no cassette player:
For cars that has neither 3.5 mm Aux-in, nor a cassette player there's some FM transmitters that features a 3.5 mm aux-in or with Bluetooth A2DP connectivity, allowing a way of connecting the Dock to the car stereo. We have very limited knowledge of this option as it has not been tested by us but theoretically it should work. Any feedback which models work well would be much appreciated!
There's more options and more variables but the above should provide a basic run-down. As there's many knowledgeable users on this forum, clarifications or comments are always appreciated. Connecting the phone's music to the car-stereo is something of high interest to a lot of people.
Our concept with the iBOLT S III Dock was to make the first (?) phone holder truly designed for placement on the left side of the steering wheel. Run the 9ft cable down the door seal and under the drivers carpet and/or seat up to the center console where power and aux-in is usually located. With the phone on the left side it is "out of the way" as far as blocking the view and more importantly, it is within finger tip reach for answering call or switching application. If you have not tried the application "CarHome Ultra" we recommend you do so as it's free for 30 days. Having a good "car panel" in combination with the right Dock placement, and the aux/BT set up as described here is very cool. The S III will become a integral part of the driving experience!
Finally, we strongly recommend connecting the Galaxy S III phone to a Bluetooth device for hands-free calling, regardless which option is used to connect to the car-stereo speakers for listening to music/app sound. To use the S III phone as a "speaker phone" while in the Dock works fine with regards to the driver hearing the other party. However, the party on the other end often hear an echo, a lot of background noise or the driver sound "faint" or like "in a tunnel". This is because virtually no Smartphone (including S III) is designed with a dedicated DSP (Digital Signal Processor) chip for cancelling background noise and echo when used for hands-free speaking. Smartphones don't have full duplex either when in speaker mode, which essentially means the microphone is at least partially shut down while the other party speak. The conversation is therefore similar to using a "walkie-talkie", where only one party can speak effectively at a time. Summary: connect your S III phone to a Bluetooth device from a respected brand manufacturer unless you're holding the phone to the ear when driving (bad idea!) or using a old fashioned wired headset.
I hope this long intro helps setting the stage for a good discussion about the best way to have the ultimate hands-free experience when driving!
