Hello all,
I would like to pose an observation to who ever the developers are for the 2.2 Froyo version for the Samsung Captivate (actual issue in bold/question italicized to skip the history). *A bit of history of what I have done with my phone* I have only had my phone for about a week now and when I got it it was 2.1. The phone worked flawlessly but I am a geek and I like to hack things to unleash it's full capacity.
Anyways, I updated using the AT&T updated way to 2.1v1 then Rooted my phone. WOW, what an improvement!!! Well I couldn't stop there when 2.2 was one click way using Odin 3 v1.30. This worked perfectly and BOOM, I now have v.2.2 on my phone. Flash works great, wireless tether works perfectly and all the other bells and whistles were all clicking together.
Before I updated to 2.2 (which for the Captivate is "unofficial"), I was able to plug my phone in using the Audio Aux port (for head phones) directly into my car stereo and use that as a sort of "Speaker Phone" while I was driving. The sound would come out of the car speakers clear and I could talk at a normal tone of voice while my phone was on the dash and the person on the other end couldn't even tell. After I updated to 2.2, the sound quality is at a whisper at full volume for the stereo. This only happens during a phone call, if I listen to Pandora or TuneIn, the sound is crystal clear.
I know that this is not the end of the world but it is extremely nice to use this when the phone is mounted and I am using one of the many great "driving apps" that are available for the Droid. The phone call is in the background and I see the Nav Maps or see speed traps using Trapster while I talk to my wife (I love this processor!!!).
I have also rooted my phone and that did not solve the issue. That was a long shot but it needed to be done.
OK, now here is the question, does anybody know how to fix this?
I am running 2.2 and use my phone's aux audio out for music but BT for phone. I will try and replicate your issue today. I am no dev but I'll see if it is an isolated incident or not.
Until then, a few questions to clarify:
1. have you tried testing the phone audio out with another device such as headset or home receiver?
2. What type of cable/adapters are you using? (3.5mm male to 3.5mm male)
3. Did you perform a master clear before going to 2.2
I'm having the same issue and will try to troubleshoot it so you know where to look. Plugging into my stereo is just like plugging into regular speakers/headphones. Going to revert my phone back to stock, do all stock update and then add this to it with the logging on. Probably won't have all the detail till this weekend.

Shovelhead84- 1) Yes, I have tried to see if the works with my computer speakers and the same issue is still occuring 2) it is a male to male cable (don't know the size but sounds like 3.5mm is the default so lets go with that) 3) No I did not do master clear before updating to 2.2 Froyo. I read that it wipes everything clean during the proccess so didn't really think that I should be now, of course, I could see why a master clean would be needed. I should have known. Oh well, you live and you learn and you share your knoledge.
makton3g- Thank you for your help. It sounds like you are going to put some realy leg work into this issue. Thanks. When you say "with logging on", is that something in SDK? I havn't began that journey yet, the SDK. so I have no idea what options are avalible...
I have this problem as well. Is there a solution?
I have begun to start flashing my captivate and have noticed that (at least to what i believe) in froyo you can not use headphones to listen to call audio. I have flashed 2 stock eclair roms and they are working perfectly with this feature. However any eclair rom I try sound is only routed to the internal speakers. I have tried Perception, cognition and even JI6 stock. None will route call audio through the headphones.
If anyone could test it on their phones and report back that would be great. I am wondering if it a bug in captivate froyo roms, or if it is just because of froyo.
*Update*
Found this thread in the Vibrant Forums. Initially they say it is a problem with froyo. However there are a couple roms which do fix the problem. So there must be a way for our captivate too.
Any one have any luck testing this on their rom?
has a solution been found for this?
i cant use any audio out =(, having the same problem with it hooked up in my car
Look for roms that have:

You are correct sir. Anything 2.2 or newer (2.2.1) does not enable audio out through the headset (even with Xcal's headset fix) unless you are using a headset that has a microphone on it.
How does the phone know? If you look at your headset that came with the phone, it has 3 rings around the plug. Left audio, Right audio, and Mic. If the phone doesn't see that 3rd ring, then it will turn off audio out when a call comes in.
The fix will cost you about $20. You can get an adapter with 3 rings going into the phone, and a female spot for the audio you hook to your car.
If you already have a 3.5mm jack hard wired to your vehicle and/or want to use the cable you have, use this:

or this:
http://www.amazon.com/Monster-iSoni...RCTS/ref=sr_1_2?ie=UTF8&qid=1295297829&sr=8-2
(what I wish I would have got)
If you have an AUX port on the front of your radio, and want another solution (new cable) buy this:

Thank you so much for your informative post.
Problem is.... $20 is too much atm. I am POOR with a capital PO'.... I couldn't afford to capitalize the or. Wonder if there would possibly be any way to work around this issue software-wise? My stereo aux cable worked great in Eclair. Problem is, I don't get al the speed and shiny of Froyo with Eclair. At least I know what the issue is now...

Pretty much nailed it. Once the kernel receives the interrupt that something has been plugged in, it checks the resistance between ring 3 and 4 (microphone and ground). If it is low, the kernel recognizes that it is either a normal pair of earphones or a line out (since ring 3 and 4 are the same on a normal 3 ring connector).
Gothpunk4christ reached out to me for a solution that doesn't require additional hardware (still want's to use the microphone on the handset). Shouldn't be too difficult to build a custom kernel that treats headphones/line out as a wired headset. The kicker is making sure the kernel doesn't disable the handset microphone.

You're awesome dude.
If anyone's looking for someone to randomly donate to, this guy is it. He's been very helpful and polite and going beyond what I would consider a helpful response in order to make this work.
So will this hit development anytime soon?

seriously.
This is majorly irritating--I use my captivate as an mp3player all the time and it's a pain in the ass to take out my headphones every time a call comes through.
I9000_reoriented_v2.3.1_bln_hpcalls.zip has a fix in it.
Enjoy.

I can confirm that this kernel does fix the call audio issue. Everything gets routed through the headphones, which is a nice sigh of relief. Thanks for all of your input everyone!
EDIT: I am pretty sure cognition 3.04 has this functionality built in to it.

As does D1ll1gaf's newer stuff.
Let me tell you about my quest regarding this subject:
I first tried using a Motorokr t505 bluetooth device that featured a FM transmitter, but the audio quality was absolutely horrible thru the car radio (too much static regardless which station you tried), not to mention the clumsy way you had to switch back and forth from phone mode to music player via the FM transmitter, coupled with the fact the stupid device was always giving you a new FM station to tune into - it just simply was way too much of a hassle plus more of a safety hazard trying to get the motorokr device to work and in the correct mode while driving. There had to be a better, more simply way to enjoy the feature of using your cell phone for conversations thru your car radio.
I've been using a cheap $15 FM transmitter (http://www.amazon.com/Coby-CA-745-W...F6G0/ref=sr_1_1?ie=UTF8&qid=1298180340&sr=8-1) I got a while back from Amazon and the mp3 music quality from my Samsung Captivate was great thru to my car stereo - I mean no static what-so-ever. The problem was, I couldn't use the phone thru the care stereo. So I rooted my phone, and now a whole new world opened up.
I up my Firmware to 2.2.1 (froyo) via superoneclick, change to a custom ROM ParagonRCS (see http://alchemistar.blogspot.com/2010/11/samsung-captivate-custom-rom-list-1110.html ), and I took advantage of the speedmod kernal (see http://forum.xda-developers.com/showthread.php?t=893880 ).
Now my Samsung Captivate, when connected to my cheap FM transmitter, can send and receive calls thru my car stereo. I also use a free app called ChoiceDialer. So now all I have to do is invoke ChoiceDialer (the only time I have to touch the phone while driving), say who I want to call, and voila - my call goes thru the car radio. Also, when my mp3 music is playing thru the radio via my Captivate, and a call comes in (which I have it setup on my phone to auto answer after 2 seconds), the music pauses and I just start talking - excellent!!!
The only slightly down side is when I'm NOT listening to my mp3 player and thus tuned into another FM station, when a call does comes in, I have to select on my stereo the pre-set button that's set to the station my FM transmitter is set to, but not a big deal - I certainly can live with that!
Sorry for the long-winded response, but you don't know (or maybe you do) how frustrating it was trying to get information on this subject. I thought bluetooth was the answer, but quite frankly, my 1st and only experince with bluetooth sucked.
The end!
I have the Samsung original car dock kit for the Note and I'm having problems with audio from phone calls not coming trough the cars speakers. Music and even system sounds go trough car speakers just fine. I already check the option in settings to use external speakers when docked. Is anyone else experiencing this problem and hopefully have a fix for it?
I'm having the same problem!
called up the samsung helpdesk NL
and they told to download a cardock app but this didn't help anything
calling back on monday to see if they can fix this
(i also came across a app that said it's not supported by samsungs own kernel.
so maybe someone made a better kernel that does support calling over the vehicle dock)

I too have this problem. I bought this thinking it would compensate for bluetooth disconnecting problems I have with my new Samsung Galaxy S2. It seems that Ice Cream Sandwich is the problem. However, having seen this dock on youtube, it seemed like the answer to all my woes. It had wired connection to the phone via the aux input and in theory should have rooted all of the audio from the phone both music player and telephone audio but like you I found to my cost that this doesn't work; telephone audio doesn't come across. I now have two Samsung products and none of these provide me with either remote or wired connection to the radio. Is there by any chance a third party rom that might cure these issues.
Nexus 7 Head-unit Install
Hi all, long time reader, first time poster. I'm working on a Nexus 7 Car Head-unit install, and figured I would post my working through the install, hardware, software, and kinda just help all the tons of people I see out there who have the same idea, but just have no idea how to go about it.
This is ment to be half a tutorial (once everything is done) and half a brainstorming to give me idea's for things I haven't thought of or considered. I'll be coming back and updating this OP with pictures, and the build as it gets worked on.
Goals of the Install
I want to be able to run my entire car off the Nexus. I have already set up wifi tethering from my S3 to get internet into the Nexus, and thus open up a realm of possibilities. Necessary features are Nav, and Music. I rarely call from my car, but in car calling would be a nice feature to have as well. I also go out to the track ever now and again, and adding car stats (boost, RPM logging, acceleration, mapping) would be great. The biggest reason to do the install is that one the hardware is configured, you literally have a ultimately customizable setup that will take years to outdate.
The Hardware
1 x 2003 Subaru WRX
1 x Nexus 7
1 x Samsung Galaxy S3 (T-Mobile)
1 x MRX-V60 - Alpine 5-Channel Subwoofer Amplifier
1 x 7 Channel Equalizer
lots of hacked wiring
The Software
This is where I would love some feedback on on what I may be missing, better solutions to what I have suggested, and just some general awesome idea's!
Music:
Pandora, Play Music, DI.fm, Soundcloud, Radio.com
In Car Phone/Text:
Talkatak, Google Voice
OBDII Support: (Future Project)
Right now this is not a nessiacty as the hardware to do this could get very tricky. However I know I can read from the OBDII port with a bluetooth OBDII dongel and an app like Torque Lite. However I do own a tatrix cable, and am considering if it would be possible to go from the USB to the tablet, and find an app/write one what allows for the tablet to control the car in real time.
Nav:
Google Navigation, Local
Track Apps:
aLapHD
The Two Builds
There are two ways to go about this. The first would be the simple and easy way which is to hack together a charger wired to the power source of the car, and use that to keep the tablet charged. Then run a 3.5mm audio into the amp, and have sound run from there. There are a few issues with that. 1. There will be no volume control, as the Tablet's buttons will be part of the center console. I suppose I can run a controller to the amp, that will let me adjust volume. 2. This will not allow for the possibility of adding OBDII support.
The second option is to purchase a micro USB dock that does audio out. Hack it apart, and run the audio to the amp, and the power to the power. This would be necessary if I want to do a full USB ODBII connection (I believe, please tell me if I'm wrong), and would be much "cleaner" when it comes time to take the tablet out of the car for any reason (hardwire sync, parking in the "ghetto").
What I need Help with
Have any idea's. Tried something similar and have some tips. Have suggestions for apps, hardware configurations I haven't listed, or just generally want to say "sick man". Please let me know. I would love to have some people who are also interested in doing this join in on my build, and we can work together to eliminate any issues to make tablet installs easier. I will be coming back and updating this OP throughout the entire process so please look for updates!
Thanks All!
(reserved for pics)
Check out a half-DIN equalizer or crossover to solve your volume, fading, equalizing concerns... can't post a link because this is first post!
I'd like do do this in the future... I hope someone comes out with a custom set of apps that make this really cool and easy... maybe even a custom ROM.
Basically what I'd want out of this is:
Auto-on with power. Auto off after 10 minutes of no power. FM radio tuner. Maybe the ability to connect a rear-view camera (wifi?). Bluetooth OBDII would be good enough for me.
I'd also appreciate the ability to connect to at least one camera and use it as a DVR, but I think that it would probably be beyond feasibility with the Nexus 7...
What I really want to see is the ability for the Nexus to be a full Bluetooth head unit. I want it to pair with my phone for both internet (already do this, works great) and have it act as a headset essentially. This is the part that appears to not exist anywhere. The ability for the Android Tablet to act as a hands free device. I mean if a car stereo can fully integrate with your phone read your address book, start and answer calls hands free, stream music, everything from your phone then why the heck not the tablet! Someone needs to write the BT stack that can handle that. Apparently it doesn't exist for android. It exists for Windows, but not Android. That is just wrong. Are there any car stereo head units running Android as their OS? If so can someone dump their rom so we can see what all it can do for a project like this?
I really want this!
I have had mine in the dash for a couple weeks now, streaming Bluetooth to the radio which I relocated, also using NFC sticker to turn on WiFi, bluetooth , set audio volume, screen brightness and start playing music. Tasker to put unit into car mode, its sick! I'll be following, really interested to see what you come up with. My car is N 06 altima and the Nexus 7 fits almost like a glove where factory stereo use to be.

Does anyone know of a micro USB dock/cable that then splits to power, usb, and audio? I know of one's that will do 2 of the three, but nothing that does all three. Maybe just a USB and power one, and run the audio straight out of the 3.5mm on the N7.
Amp was ordered, and will be here next week. Prelimanary fitment pics coming soon...
Hello, I'm considering permanently mounting a nexus 7 in my car. It seems like the perfect in car device.
With this in mind I have updated my CarHome Ultra app to better accommodate the Nexus 7 screen. I will be posting a new video soon showing it running on the 7.
I've looked at doing this as well, I've always been prevented by the issue of the FM radio. I use the car a lot in places where I get no or poor connection via the phone, but the radio works fine, so loosing it would not be an option as I use the FM radio quite alot.
I've been trying to figure out away to control an FM radio via the Nexus so if anyone out there has any info it would be greatly appreciated.

I am actually currently doing a very similar project with a Nexus 7 and my Nissan 350z
I am planning on installing the Nexus 7 inside my dash (to replace sat nav dash)
HOWEVER
what about routing the power button on the tablet? Because If you cant access the power button the tablet will only get power when the car is on and if you dont use the car for a day or two the tablets battery would go flat and next time you turn on the car the tablet would go into charging mode (screen with charging battery only) and not boot up into android jelly bean.
Theres 2 potential solutions:
1. Open the tablet and wire the power button to a custom one, however on opening it I have found the button is actually a physical push press button and cannot be wired.
2. There is potential to change a file on the android system to tell the tablet to boot up when a charger is plugged in, check these threads:

Hey all
Just to add to the discusion;
Radio/DAB
Frontier silicon are the only company that I can find that do an app that can control an external radio and stream it's signal to the tablet as opposed to picking up the signal over the cellular network.
App:
Their page
http://www.frontier-silicon.com/products/software/DOK_App.html
Play store
http://tinyurl.com/d24gwm4
Module:
http://www.frontier-silicon.com/products/modules/briefs/Venice6_PB.pdf
now the problem with this is, aside from building the module in somewhere' the audio out as it feeds out of the module, but I was thinking I could use some form of y split cables near to my amps 'in'.
Media storage and playback
As far as storage for everything video/audio atc and a player to match I was thinking of useing xmbc
http://xbmc.org/
andriod port;
http://forum.xda-developers.com/showthread.php?t=1813089
and pairing this with a WiFi DLNA HDD that I would wire in remoted off (say in the boot)
GPS
For improved gps I was going to use an external bluetooth gps reciver then allow mock locations on the tablet, there are also a few apps that help with this.
This app seems to have good support and a nice help page.
App:http://tinyurl.com/a9s7gvo
An example of a external GPS receiver
http://tinyurl.com/a339vu7
Hands Free
The only work round I seem to have found atm though far from perfect is this
http://www.scosche.com/consumer-tech/product/1919
it allows you to to 'cut in' the audio stream, but (can't fins the tread now will keep looking) the guy who was playing round with this was having audio issues.
not an idea solution but workable.
before my mind starts melting again;
How I plan to implement the tablet is to use tasker to wake the tablet when power is supplied then shut of down after, if I disable all kinds of connectivity when tablet shuts down then reactivates when it wakes up everything should run smoothly. Power will be cut because I'll wire in the ignition live, like you do in a stereo anyway, an this shouldn't put a drain on my battery to much, an if the dash build is good it shouldn't be too much of an issue extracting the tablet to hard boot anyway.
Volume and Audio
Volume and audio quality is another issue that needs to be addressed.
http://tinyurl.com/d2zbbnf
Seems like an ok work round.
Another way would be to install a direct in-line volume control as suggested in other threads, and put in an external DAC or hardwired EQ.
On a side note I came across this........ http://www.crutchfield.com/p_773AIRDAC/NuForce-Air-DAC-Receiver.html?tp=59282 ........ although you need to use their plug in senders but I'm sure this can be worked round with the knowledge on this forum, an would provide a very nice solution. then again there are quite a few bluetooth devices around. this probably wouldn't allow for in-line controls though.
well thats it for now, hope this helps push this forward to a working system

Hi, I've been following the forum for a couple of years and its helped me out a lot, I've never posted before but I can't seem to find an answer on this one. I've fiberglassed a nexus 7 dock in my audi tt, at the moment it's going nexus 7>pogo pin dock>headunit>amps>speakers. There have been a few issues regarding volume control, as you may know the volume controls are disabled because of the output being line level, at the moment my headunit is mounted behind some trim under my steering wheel which is really a good solution. What I was wanting to achieve is to have a pre amp equaliser up front for volume controls so I can get rid of the head unit completely, and a dac in between the dock and the equaliser. The part I need help with is figuring out if the dock itself is a dac, I believe that on the Google Play store description it does say the output from the dock is 3.5mm analog, if that is correct, then I'm wondering does the internal dac of the nexus 7 convert the signal through the pogo pins, or is it still digital right up until it goes into the dock? If so, then I'm thinking would it be possible to still use the audio pogo pins, disconnect them from the docks internals, and then just wire them straight to a dac? I hope all of that makes sense. I can't post link to the thread of the install, but if you Google audi tt tablet install, it should be the 2nd one down, thread title is just called tablet install, thanks
