Car Audio & Galaxy S3 as head unit - there is no "Winning".

Car Audio & Galaxy S3 as head unit - there is no "Winning".
Okay, so for those of us who like to use our phones as a car stereo media source, there just is no 100% "Winning" that I have been able to find.
ANALOG USB AUDIO:
Sure, both TouchWiz and some AOSP ROM's support this. But there are two issues.
1) TouchWiz sucks (IMO).
2) The sound has "low level background noise" (IMO).
3) AOSP docking does not work properly, such as the CarHomeUltra does not get to disable the "home" button like it's supposed to.
DIGITAL USB AUDIO:
Okay, TouchWiz supports it but has lots of "cd-audio type skipping sounds" from time to time. No current AOSP ROM supports it. And because the USB-OTG connector requires certain pins be used on the connector, you lose the auto-dock feature regardless of ROM.
BLUETOOTH AUDIO:
It's a crappy sound for audiophiles. It's just so down compressed, it's useless for some ears.
APT-X BLUETOOTH AUDIO:
Better quality audio, but AT&T has already warned me once that I will lose my Unlimited Data plan if I keep using Bluetooth to my car stereo. And bluetooth in general is a "quirky" working technology that irks me sometimes.
What do I want? I want to be able to use a USB-DAC on an AOSP ROM and keep the auto-dock feature.

APT-X is a Bluetooth codec that provides higher resolution Bluetooth audio.

He's a little wrong there. Apt-X is an audio codec that is installed in some high end phones, and is starting to become the standard. Currently no car stereo has the capability of using this codec, but they will probably be on the market by the end of the year. Apt-X is preferred over A2DP because it is loss-less, so the audio quality is the same as plugging your phone in with a AUX cable.
AT&T is blocking you from using the Pandora app on your head unit, because technically it is tethering. The app simply sets up an Ad-Hoc network, and uses the phones internet to stream Pandora that runs on the car stereo.
But...To answer your original question, I would suggest using the standard headset port on your phone. The DAC on the USB plug is generally software driven, and will not give you as good of sound as the standard headphone jack can. If your not satisfied with the quality, get CM10 and DSP Manager to fully customize your sound.

Ummm. Auxiliary? I use it my cars all the time sounds awesome with awesome beats .

CZ Eddie,
I feel for you...because I am going through the same dang crap.
I am surprised you have not corresponded more with me bro. There is hardly anyone out there that seems to be on this One Handed docking quest. Even though there have been HOW MANY MILLION S3's sold...we are in an unpopular niche.
The skipping that I experience is most severe when listening to MEDIA while dialing out, during a call, and during an incoming call ringing. It is like a stuck skipping CD digital like sound. The author of SoundAbout app, is trying to help me solve this issue but he does not have the usb/otg/dac arrangement that we do. One version of his app, eliminated at least the stubborn perpetual skipping, but has a byproduct of losing the media stream after a call...which requires unplugging/replugging the usb cable.
I had such a terrific setup with my old HD2. It was a lightly modified card dock but one handed docking providing POWER and AUDIO via 2 ports, usb and headphone jack. What I am sure I will have to end up doing, is having to connect the Headphone audio out by HAND as a 2nd step. At least, I will have NO SKIPPING, and all audio including CALLS coming into my car deck without any weird bumps!
If I had chosen to go USB analogue out, I get really bad noise but only when charging. Somehow, when it's charging, I get hiss, switching sounds, clicks etc. I can almost 99% confirm it is not ground loop type issues.

1) Regarding aptX: probably, it won't be aptX Loseless that makes it to car stereos, but simply aptX. The Loseless codec looks to be targeted for professionals. But, still aptX is still many times better than the ugly old SBC codec.
2) The codec will change, not the protocol: AptX replaces SBC (not A2DP). A2DP (the transfer protocol) can use whatever codec it wants. So, whenever the car stereos are released, it will be A2DP with aptX. CSR has already released an aptX Bluetooth chipset for car stereos...someone just needs to pick it up and use it now, haha!
3) Concerning BT streaming and "tethering": not to derail this thread since you already have one about this, but I think they're bluffing hard. That representative is confused and wrong. I imagine if you pressed them to provide evidence or explain what their definition of tethering was, they would fail magnificently.
----
BT is reliable for me; I mean, it's as reliable as my WiFi when I want to use it. What quirks have you experienced?
--
For enabling docking -> hmm...what about using a NFC tag? This one enables docking modes. Or, maybe use a Tasker to detect Bluetooth connectivity?

Auxiliary cord.

IMO an audiophile would never want to use their phone as their main audio source.
And you do realize that achieving true audiophile sound quality in a daily driver is all but impossible?
If your streaming Pandora your not getting anywhere near lossless quality so why not use Bluetooth? Bluetooth audio streaming has come along way. If your standard audio file on your phone is a 320kpbs mp3, your not missing anything streaming via Bluetooth. I was once skeptical about this until I finally found a good pair of BT headphones.
I'm interested to hear more detail about your car audio setup. My setup is decent, better than most everyone else I know and IMO the only difference I can hear between Bluetooth streaming audio from my phone and the music on the sd card in my stereo is the over equalization from being equalized by the phone and again by my sound processor.

Normal Bluetooth vs. other methods has an obvious degredation on the sound for me.
Yes, Pandora sounds bad even when the "high quality" selection is checked off and I pay for the higher resolution.
But, normal Bluetooth makes Pandora sound even worse, according to my ears.

Wow. I hear a boatload of difference between Bluetooth and otherwise. But I'm 42 years old and maybe my ears are just more fine tuned than yours are.
I'm using APT-X [high definition] Bluetooth right now and it's the best compromise in sound & convenience I've found so far.
I keep meaning to write up a DIY on how I have things set up. Just haven't gotten around to it yet.
Btw, you're is "you are" and "your" is not.

I wouldn't full on call myself an audiophile (too poor to be one as student) but I love higher end sound. I personally prefer an aux cord for sound, it's a little less handy I guess but so far gives the best bang for your buck as far as sound goes.

Depends. If your charging cable is too close to the aux jack you'll get electrical feedback. Had it happen with my FM transmitter...I have one of those 1->2 12V adapters with a USB port. Whenever the USB port is used it produces quite a bit of it.

I have to agree with most of what has been said here on the S3 not being up to snuff for car audio. First I will say its my favorite phone I have ever had. Just about everything else about the phone rocks. But when it comes to car audio, I have to say its the ONE and only thing I will give props to my old iphone...using the usb direct to the radio that not only played the highest quality music, but it charged it as well at the same time with one cable and nothing else to do was kick ass. I dont get why if Ipods and Iphones can make this work so well, why cant these guys? I know most stereo makers lean heavily to the iphones and android as a whole is sorta looked over for the most part, sure it may work with android, but they have all the hardware and most things are geared towards iphones. I use either a samsung hs3000 for bluetooth audio or just give up and use the aux, but neither is as good as the iphone on usb. Even the ipod/iphone on aux is not as good as usb. So it works, but your settling for sure.
Alot of times I still will just put the ipod in the car if I really want the better music quality, but I would much rather have an all in one with my phone for music, nav and calls while driving.

Seen a few stereos with mirror link that look like they would be great for android. Almost bought a sony with it but decided against it due to having to go back to a touchwiz rom as well as I'm hoping miracast will make an appearance in some stereos in the future.

iPod quality sound on Gnex?

Hi, I have beats headphones and an ipod touch, I also have a Gnex. When I listen to music on my ipod they music sounds great with no kind of audio eq or enhancements but on my gnex the sound is not even close, I have the beats + xlouder patch installed along with trickstermod volume boost and hq sound but I can't get the same sound using either awesome beats dsp or noozoxide. My question is, is there any way to change my settings to get it to sound exactly like the ipod? If it's not possible I understand but I thought I would ask here before I gave up hope and just deal with it. Thanks!

Not with software. GN has a ****ty chip and that's it.

My friend I have the same problem.
The solution is the mp3 file quality.
I find that downloaded music is at 128 or 192 kbps and you want iTunes or Google play music quality at a higher bit rate like 320kbps. My best sounding files are the .m4a or the iTunes rip format.
Idk if converters work but find a good one because some convert too fast and ruin it so find the highest rated one.
[Edit] when you use iTunes to sync music, it converts it to the format for the iPod to play. Try using Google play music download thing (their iTunes) and sync your music through play so maybe they convert it. Because I drag and drop but noticed sync music sounds more premium on my beat tours.

I have been using this for a few months and is by far the best of all the audio mods and enhancements I've tried. The only thing I don't like is that sometimes music sounds distorted or the bass is too low or high so a lot of the time I find myself changing settings after a new track comes on.

I just love that the Galaxy Nexus' audio output is way better than my ****ty iPod Touch 4th gen...
The iPod puts out very flat tones while the Galaxy Nexus puts out punchy tones making listening to music a joy instead of listening to the capital B BORING music output of an iPod.
Friends of mine constantly get amazed by the sound quality of the Gnex. It just has more bass and more intensity to the music.

I'd the Nexus supported USB DACs the ****ty audio chip would be a non-issue. But as everyone else said, lossless audio helps a lot. But if you need to go lossy for space, 320kbps constant or 160 to 190ish variable bitrates are what you want.

You at least need decent Music track Quality at least 192Kbps. Im always on 320Kpbs
I use PowerAmp and Sony High Bass Headphones and the quality is brilliant. I mean Beats (In my opinion) arent even that good. your absically paying for the name "Dr Dre".
But what ever floats your boat!?
No point in boosting audio volume if you have crappy audio quality?

That's an euphemism for bad quality when it comes to headphones .

The key is using flac audio! Gotta use HQ stuff. I notice instantly how it sounds like garbage when I come across one of my old tracks that are only 192 or even lower. I use sennheiser HD650`s with an amp. I notice when quality drops. But if you keep it to HQ I truly feel the gnexus sounds great. Much better than my nexus 7.

Try the power amp music player in the play store(15 day trial) you can increase the base and treble. That alone made me buy it.

As most said, the file quality needs to be high. For MP3 it should be 320 KBS CBR or VBR at "0" setting which usually equates to files in the 200-300 KBS range. Personally, I think VBR0 format is better than 320 CBR. Most people cannot tell difference between FLAC and 320 CBR unless they have very acute hearing and very high-end headphones. Speaking of headphones, get a set with built-in amplifier if you truly want to hear music the way it should. Sadly most of those headphones are in the $200-$600 price range.
If you're using the Gal Nex with high bitrate files and high end headphones you'll notice it's hardware limitations but for most people the Gal Nex really isn't that bad.

beats headphones are such crap lol

Hint to OP: Just because it says "Beats by Dre" does not mean that they are any good.
Sure, they have a heavy bass, but at the price of almost drowning out hi and midrange sounds.
Try other headphones that are actually worth the money of the Beats, like stuff from AKG, Sennheiser, Beyerdynamic or Shure.
Beats are merely a fashion-statement, and I have to admit that they look cool, but no self-respecting Producer or DJ would use them to listen to music on a daily basis.

Poor Sound Quality

Ok, has anybody else noticed the poor sound quality when you playback music on your headset? There's a hiss and you sometimes here sounds break up. I noticed this last night while I was playing music. I didn't expect this on a premium device. Really disappointed, anybody know if this has been mentioned or is waiting to be fixed?

I don't have that issue but I use Google Music.

Doesnt appear that anyone in the audio review thread are running i to this issue, may be a faulty unit worth getting fixed, or atleast try the audio on a store unit with your headphones and see how that goes.

I was listening on the earbuds it came with earlier and didn't notice anything when using Spotify. Just now used it with my Audio Technica ATH-M50s and still no hissing or breaking up with Spotify. Spotify and Google Music is all I use and I stream all of my music. Not sure if that makes a difference.

You can shut off boomsound in settings when the aux cord is connected, I also find that visualizer increases distortions when playing certain files so try not to have the music player on visualizer when playing through the headphone jack.

Bluetooth Quality

Is my phone defective or have more people noticed how bad the quality of audio is when playing through bluetooth? I've had a lot of phones and this is the first one that sounds like this. Everything plays perfectly fine as far as the connection goes, but every song sounds noticeably bad. The best comparison I can think of, considering I don't know much about audio terminology and the difference between 320kbps and 192kbps, is when using an auxiliary cable it's like a 1080p HD video and when streaming via bluetooth it's like a 360p video. Am I the only one experiencing this?
