dock for Samsung Captivate

I'm looking for a device that will allow us to connect our captivate to our a/v receiver so I can listen to my songs.
Thanks!

Kinda like.... 3.5mm to RCA?

This is what you're gonna want, if you're actually looking for some sort of dock like some surround sound setups come with for an Ipod I don't think you'll find anything like that.

So that 3.5mm port can only do analog output?
Thanks!

If you have a receiver that can take USB mass storage as a source, you can try using the USB cable and setting the USB mode to mass storage. Or if you have a receiver that can take bluetooth stereo audio, you can use the bluetooth. Otherwise, analog output from the 3.5mm will have to do.

[Q] Audio line-out for Galaxy Nexus

Hello all ,
Is there a way to get an audio line-out from the Galaxy Nexus, either using an adapter or a docking station? I'm not looking for a solution like the one offered by the Samsung Galaxy S2's car dock (which streams bluetooth audio from the phone to the dock, then the dock turns the bluetooth streaming to analog audio through a 3.5mm port) but rather something like an adapter for the MHL port or from the docking station.
Appreciate all the help!

The obvious solution (at least to me) is to plug into the headphone jack. You could also use either the media dock or MHL adapter in conjunction with an HDMI-to-analog adapter such as the one linked below:

He's asking for a line out solution because it will bypass the internal headphone amp that is utilized when the 3.5mm port is used. If you're plugging the phone into speakers or a sound system that way you'll get much better sound.

If the mhl -> HDMI cable adapter carries both audio and video, you could use an hdmi breakout adapter to split the digital audio. It depends on the HDMI output capabilities of the phone and the acceptability of digital audio for your needs.
Edit: would no doubt be a cumbersome solution. It all comes down to your usage scenario for the output.

Thank you vespoid, ardabey.
What OJ in Compton said, I'm looking to bypass the internal headphone amp, not sure if there are any details on the car dock or desk dock, I hope 3rd party manufacturers come up with something, any solutions are welcome.

Never thought about this, but a contactless dock with HDMI out directly to the AMP = audio bliss. Thanks to the forum for letting me see the obvious

Bumping this thread...has anyone successfully done this? I want line out audio for my car's 3.5mm AUX input - had it with my ipod and it sounded much better than through the headphone jack, as well the convenience of not having to maintain two volumes.
Hoping the official car dock that uses the 3 pin connector and has a 3.5 out would do this, but I'm worried it will just use BT to transmit the audio to the dock like I read the Nexus One dock did.

I wish too that the NG had line level out.
I think it's a limitation of the hardware. I think Apple is the online one that really uses line level out via it's dock connector.
I hope someday Google will use some sort of line level out on their reference hardware or built support directly into a newer OS.
I remember my old Dell DJ had line level out. Soooooo much better.

There is nothing wrong with the 3.5mm output sound quality wise.
Trying to drive headphone-like impedance (lower) with a line out isn't the best idea, but driving higher impedance inputs like your car deck isn't that bad as long as you let the amps do the "work" of boosting the volume and not your phone. While not optimal, the decrease in sound quality shouldn't be very noticeable.
The main advantage of the digital audio though USB (what apple does) IMO is that it eliminates the need to have both the USB plugged in to charge and the 3.5 mm cord for audio. It also allows song data to be shared and device control from the speaker/head unit. Good setups will recognize most android devices as mass USB storage and provide the same functionality, but I'm not sure how the MTS on the GN will affect this.

I would wait and see how the audio quality is from the dock. Even if it is bluetooth, the audio quality may not be that bad.

The problem is, that if the head unit supports MTP then yes it can read the device like mass-storage, thats fine, but it doesn't allow you to stream media from radio apps, youtube and turn-by-turn directions from gps, this is what we are looking for...
technically it's not sending analog audio output through the USB, its just reading the stored media on the phone.
I have read that samsung phones are able to accomplish sending analog audio through the USB while charging, with the correct resistance values (adapter) or possibly with software pointing the audio in that direction (for example code build into the framework/API)
this is one major thing that Android lacks over iPhone, this problem should be addressed ASAP. I'm hoping CM9 might be able to find a solution for this.

I agree, i hope they fix this soon toi. It would make the development of accessories much easier for all android phones. Seems like a no brainer but I guess Google has other priorities...

Just starred this, if the hardware is able to do that I find it completely stupid that they do not allow it.
Smartphones audio amps are not exactly famous for being top-quality so having this possibility would be great.

Thanks. The lack of this feature is ridiculous/mind-boggling/suprising.

Well, if you were waiting for the card dock to solve your problems... it doesn't. Plugging into the dock's "line out" gets you amp driven sound. I really do not understand why this is such an issue for Android. When I plug somoething into my 3 year old Nokia smartphone a window pops up for me to choose headphones, headset or line out. Why can't ICS offer the option and if in the car dock, default to line out? A USB solution is not going to help if you are using the car dock.

Which if I understand correctly uses Bluetooth to transmit compressed audio from the phone to the dock, then delivers it through the 3.5mm jack. Why not just have a digital signal go through the USB port!?

actually the pogo pin transfers the digitial audio and the dock decodes it into analog to the 3.5mm output

play music in car

What's the best/optimal way to listen to music in car?
I used those tape cassette things from Griffin, they're good but they break/wear out easily.
I don;t have AUX in the car. Any suggestions?

I'm not going to help much - I have one of those cassette thingies. I have used it for many years now, and it has never broken or failed. I use it for about an hour every workday, and on long trips, some of over 9 hours.
Another way I found and used for a while (no idea where it is now) was an FM transmitter. You plug into a 3.5 mm socket, and it transmits on a selected FM signal. You then just tune your radio to that frequency. I found a bit of interference, so I went back to the cassette. That also does not require batteries or cable (except audio).
When I abandon my current 13-year-old Volvo, I may try and get a car with a BT music receptor for the stereo. More likely I'll settle for one with Aux in.

I have an Aux input and a USB input but Im playing music through the bluetooth link. Ive given my GPS away and just use my note now with the google nav.

I bought jabra cruiser (Bluetooth hands free with FM transmitter ) and I have it in my car .
Once I am in I switch it on and it pairs to my note and transmits through FM.
It is a very good and handy accessory for those who doesn't have aux in nor Bluetooth stereo systems.it even have music control buttons which work perfectly well with my note.battery life is amazing too (lasts around a week with an average of 1hour playback, it can auto switch off after a few moments of inactivity so ubwont have to worry shutting it down ecevrytime )
I can't recommend it enough bcos of its many other features...
Hope this helps

Pioneers only support pandora on ios devices. At least my unit does. You can ofcourse stream whatever you want via a2dp bluetooth connection. Regardless the app you use to reproduce audio.

Quick question to add to this, I am looking at getting a new car and chances are it will have aux-in, usb and bluetooth connections.
I know the aux-in will just plug straight into my Samsung dock, but what about the usb/bluetooth.
Will I be able to control the phone music from the stereo with these, or will the usb connection even work?
That Appradio2 looks smart, hope it comes to the UK.

Get a pioneer car stereo with aux-in. I just got their cheapest model with aux for about $70... Great sound, it has built-in 4x50watt mosfet amplifier and also line out if you want to upgrade using your own amplifier.

all new pioneer units can stream whatever music app from android as long as the device supports a2dp.
When you see the Pandora logo on pioneer devices however, it means that this pioneer device can control pandora (next, previous, radio selection etc) on iOS. that's all i meant.
Just don't expect the head unit to control your pandora app on android.

The answer is probably yes for the Bluetooth, probably no (in my limited experience) for the USB.
Bluetooth does remote control through the AVRCP profile which works with the Note. As long as your stereo does AVRCP right, the note should play along.
USB is hit and miss. Most of those systems either expect an ipod attached or a simple mass storage device.

I didn't want to play around with installing a new stereo as it was a but complicated in my car. Went with the Parrot MKI9100:
www.parrot.com/uk/products/hands-free-car-kits
It's basically it's own separate amp rigged through existing setup. Sound quality is fairly good, it does have an output if you're using a power amp.
It's got full a2dp, syncs contacts to use it's own voice recognition which is much more accurate than built in Android. Voice quality is great to hear other person, not so great for other person to hear you. Big bonus is that it also has connectors for latest gen apple devices, USB, and 3.5 audio so pretty good options. Other bonus is it's well supported with firmware updates, had 2 since I've had it which have improved device compatibility and voice quality.
Installed it myself, was pretty easy once I'd looked at the wiring diagrams.
For the price though, I would probably have bought a high end double height new stereo as they have all this built in.... however, I'm a slave to impulse buys

Yeah i was a bit confused how it would recognise all the music in the 32gb of data on the phone over usb.
Probably won't bother me in the end, will normally have it in the dock to control it on long journeys anyway. As long as the music plays through usb I don't care.
If I plug it in USB how will the phone know to send the music via that rather than its own speakers like it would do with the aux-in??

If you play through Aux out:
Galaxy note reads a file on your SD (or internal memory) and the CPU feeds it to your audio chip that converts the digital file into analog voltages that go out your headphone jack and into your stereo. The quality is limited by the encoding of the file and the quality of the Note's audio chip.
If you play through A2DP:
Same as above but the CPU feeds the file to your bluetooth chip. The quality is limited by the bit rate and encoding of the A2dP protocol.
If you connect via USB to your stereo:
Your card (or internal memory) is read by the stereo, not the note. The stereo converts the file into audio output. Quality is limited by the file encoding and the quality of the stereo's sound chip (which is probably better than the note).
Make sense?

Sounds good to me. I just hope that the usb cable works with my car dock (official samsung one)
Ideally I would be able to stick a usb cable from the dock to the car and it would charge and play music, instead of me having the usb port taken up by the charger and having to use the aux-in port.
If that makes sense...

Probably will work and I am interested in your results. One minor issue is that your stereo probably will only supply a small charging current to the phone so it won't charge as fast.
You might have to put your phone in mass storage mode but maybe not. Let us know if it works.

My note does not play music via bluetooth. Car is opel insignia if it matters... Any ideas how to connect? Accept of course to turn the car is on .

I have been using a Jabra Cruiser2 with all of my cellular phones and highly recommend it. The sound quality over bluetooth+FM is, somehow, is better than what I get when I plug the phone into my vehicle's aux input.

i just tested a2dp in my MVH-8300BT pioneer and turns out that the new pioneer units do not support BT music streaming and require a bluetooth module (sold for ~150$). Aux cable for me

[Q] 3.5mm to standard USB for car stereo music? [RESOLVED - IT'S NOT POSSIBLE]

Anyone know if I can take a 3.5mm to USB cable. Plug the 3.5mm end into my headphone jack on the phone. Then plug the USB end into the USB port on my car stereo, and listen to music that way?
I know there are other ways of listening to music, but I need the answer to this particular question for something more complicated that I'm researching.

No, can't be done.
And the only way to connect to car is with SGS3 Easy UMS.

Our phone's 3.5mm headphone jack is TRS (headphone) or TRRS (headphone and mic) only. Devices that use the 3.5mm port as a USB port specifically state that and only support charging and USB data (to put music on the device). You would need a separate device to convert the analog audio out of the 3.5mm to digital and stream it over USB and even then your car's headunit would have to support streaming digital audio over USB. Our phones do support streaming digital audio (USB audio host capability) out the micro USB cable though.

Bummer, okay thanks guys.
I think I posted in the wrong forum also. Sorry about that.

Bluetooth to aux car adapter, best quality/high volume

hi there....
i am looking for a new bluetooth to aux adapter to listen music/navigation/google now etc when driving my car.
My car stereo doesn't have built in bluetooth but got an aux plugin and i tried 2-3 different kits that works quite good except for the volume level that is always lower than fm radio (15/20 for radio means 35/40 from aux)
I thought was because of the aux input until plugged my chromecast audio and find out how loud and rich is the sound i can get from the aux plug with a good source.
Unluckily CA is not a solution, so i'd ask if anyone knows a bluetooth to aux adapter that has the same (or near) quality that can experience with a CA.
Also had a chance with usb DAC that is great, but i don't want cables....
