Ok so Ive been looking in to building a Android tablet in to my car to use as a head unit.
Basically im running amps in my car so i need an audio signal from the unit.
I DONT want to simply run the 3.5mm headphone jack cable to the amps cause it will sound shocking.
I was just wondering if there are other ways of doing it.
I was looking in to something like sending the audio out the usb.
But what interested me was using using the OEM desktop dock with HDMI and using the HDMI audio out and using a DAC (digital audio converter i think) and converting the signal to analogue.
Does anyone know if this is possible at all or if there are better ways of doing it?
Ive been spending hours trying to find out a way of doing this!
I'm working on this same project. I bought the dock connector to get access to charging and a line out simultaneously. The regular RCA adapter doesn't give you the ability to charge. I'm thinking the amps will be fine with the line output.

Is there somewhere available the BA bottom pinout?
Does anyone know, wetgher it is possible to obtain audio signal via the bottom connector?
I have been wondering about the same thing: I'm using a "docking" station in my car which all it does is charges the phone. It would be nice if I wouldn't have to put the mini-jack connector in the audio-out to get the music playing via the car stereo.
Hello,
this one is for the HIMALAYA, I guess they are compatibel but iam not 100% sure. In my own deveopments (RS232, USB, Audio, Freespeech) I used this diagram http://wiki.xda-developers.com/index.php?pagename=Connectors
yay, it seems I can build an universal docking station connected to my home audio system
I already have a 2.5mm -> 3.5mm stereo adapter to connect my Mogul to my car stereo.
I want a 2.5mm (M) -> Splits two ways:
a) 3.5mm (F) stereo
b) 3.5mm (F) mic
If there isn't one commercially available, I should be able to make it. Any idea what the proper pinout is? And how do we get all signals down 3 wires? (Left+Right+Mic+Gnd+control button)
Any update on finding out how to conect a external speaker and mic to the 6800? I would like to have this type of setup in my car.

You can do a direct splice of the cables coming out if you want, but that requires a little bit on knowledge and a little bit of testing. Basically, you'd take the stock headset and cut off the earbuds and mic. You'd then splice the headphone fead and the mic feed into other lines that would run to your external speaker and mic. Other than that, I don't know of any attachments that do it. You could swing by radio shack and ask them.
I am also interested in doing this. My car has an aux input to the stereo and I would like to install some kind of mic setup so I can use it as a handsfree device. Bluetooth is way too unpredictable so I plan on doing it wired.
You will need a 4-conductor 2.5mm plug along with the Y-cable that came with the phone that has usb and 2.5mm jack.
anyone looking for this setup.. i have a cable i bought off ebay that has a miniusb,which allows you to have a charger plugged in, built in microphone and answer button, and a 3.5mm headphone jack, it works great in the car for hands free (car deck has aux in) , and also works great with my cigarette lighter fm transmitter. anyone looking for this , just type in m
I think i found a solution. I just bought an adapter like this one:

Hi guys,
I bought a new Samsung TV the other day; it has RCA input but no RCA output.
I have some wireless Sennheiser RS170 headphones that connect via headphone jack or RCA output. The headphone jack works fine but mutes the tv speakers, so every time l'm not using them have to remember to unplug them (on the back of a 46" tv!)
However, connecting via RCA, I can leave them plugged in and works ok.
Anyone know how I can get RCA output on the tv, if at all? I seen some scart to RCA output adapters, would this work?
Cheers.
Owen.
if you had a receiver amp you could plug the rca in to that, or I believe if the TV has an optical output (should have) you can get a converter to change the optical out to an rca. http://www.amazon.co.uk/gp/aw/d/B0074JZ8ZW
sorry to say but most new TVs only have an optical out these days to run audio to a sound bar or amp.
you can get a two rca to a 3.5mm jack plug which would fit in the headphone socket of the TV but you would likely have the same prob of muted TV speakers.
My Samsung UN32EH4003FXZA HDTV has NO Audio outputs & no BT. I knew this. Now I want to use my BT headset. And will the picture remain since the VGA connector won't be used?
I bought a Anker Wireless Bluetooth Stereo Transmitter and Audio Receiver 2 in 1 Adapter.
http://smile.amazon.com/gp/product/B00E174RTS/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
Uses a 3.5mm to 3.5mm cord. Wasn't thinking right thought I could connect this to my HDTV. I can't, directly anyways.
Did a bit of research. I want an inexpensive solution. Can I use a HDMI Male to VGA with 3.5mm Line Out Audio? Here's two I'm looking at:
http://www.ebay.com/itm/251744316365?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT
http://www.ebay.com/itm/381114657643?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT
Will one or both send Stereo sound to the Anker Wireless Bluetooth Stereo Transmitter and Audio Receiver? Again eBay items 251744316365 & 381114657643.
If either of these won't work. Are there any ~$20 USD & under solutions? I can return the Anker BT Transmitter if needed.
Edit: Just bought a 1.5ft Premium 3.5mm Stereo Male to 2RCA Male cable by Monoprice through eBay $4.52 otd. Looks a lot better than the other cheap cables for less. Connecting it to my cable box.
Yeah those 2RCA to 3.5mm cables come in quite handy sometimes.
What I usually do is to plug it into our family's 15-year-old sound system and connect the 3.5mm into our phones when we have friends over. Decent solution when I don't have the CD, or want to play the latest tunes, or don't want the TV on to Chromecast youtube
Awesome! Bob's my uncle.
Translation: It works.
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.
