Hi all,
I am about to buy a (yamaha) AV receiver.On the specs page it mentions USB Input for iPod/iPhone, USB Memory and Portable Audio Player.
Can i use the HTC Desire as a usb audio player???
I mean i want to connect the desire via usb to the AV receiver, to use it as a a player and not as a mounted SD card (usb memory).This way it will be charging while i can change songs,playlists,fwd,rew, etc....
Has anyone done this?
I know i can connect it to aux port (jack->RCA) but it will not be charging.
I assume that same question applies for car stereos with USB (usb ports that support Portable Audio Player and not just usb memory loaded with music files)
ps. i searched for similar threads on xda but could not find one....
No, you can't play audio files over USB like that. Only with the 3.5mm headphone jack. It's also damaging to the battery to charge it between full charges and in short intervals.
I assume that this is a software limitation.
So far i 've used only the official rom and the revolution 3.0.
Is there a chance that some other rom (maybe aosp) supports usb media player?
I noticed on a samsung galaxy s that there are three options for usb connection: usb mass storage, samsung kies(something) and media player.
For the battery issue, lithium batteries are supposed to be less vulnerable to poor usage but why assume short intervals?I want the desire to charge simultaneously so i can leave it playing for a couple of hours.
I would like to build an Android car infotainment device to replace all my gadgets inside the car. One option would be a micro PC with USB touchscreen and a lot of devices connected via USB. The other one would be an Android gadget, either small tablet or TV box.
The biggest question I have is: what Android devices support 5.1 audio? This is a must, though I actually can use only 4 channels. What audio formats are supported for this?
The other question would be TMC - the FM kind, not online.
Are there any embedded platforms out there (except PC and Android) which support multi-channel audio?
Has anyone done this before? I might be reinventing the wheel.
No updates? Either nobody knows about Android 5.1 sound output or they are working under NDAs.
Are you planning on keeping a headunit to control volume, do you want am/fm radio, etc....
without a headunit you will need an amp where you can use the headphone to rca adapter and usually its the amp that would add front and rear to the left/right output of your android device so you would still get the 4 chan output effect. to go for the 5.1 chan you will need another device that actually controls the 5 speakers plus the subwoofer which might be tricky but I'm sure its not impossible.
the setup I was going to go with was a amp that I can mount its power controls (left right front back and volume) (or amp/eq combo) to where I can reach it and build a mount for a 7in (possibly diff size not sure depends on how it will look) and use the heaphone to rca adapter to power the audio and put the usb inside the dash possibly with a little hub if they make it (that way not only is it getting power from it, if it allows, the addition of say a thumb drive with added music/movies. some tablets/phones have fm radios built in as long as something is plugged into the headphone jack (my new phone doesn't seem to have it but thats a feature I will be looking for in a tablet)
4chan amp
eq that would allow 2 chan in and 4 chan out plus sub out (if you have a separate sub amp)
I just want to know if there are any android devices that are able to stream 5.1, I can take it from there. Same question about TMC support.
Some details:
My car is already fitted from the factory with 4 channel preamp and 12 speakers including subwoofer low-pass. It has low-level input for those channels, worst case I would buy a preamp.
FM is pretty much given on most Android devices, probably excluding some tablets, but I won't actually miss it if it's not there.
TMC would be nice since all Androids usually have a GPS sensor and sometimes compass.
Anyway, it was mostly a request for suggestions or even a rant - I'm surprised that something like this doesn't exist yet. With the exception of dedicated units going >$$$-$$$$, an alternative set-up would be a medium-range blueray player coupled with an Android tablet. Music control could be set up with DLNA, bluetooth streaming or mixing player and android audio would be a bit harder but not impossible.
hey friends
this is a nice thought and you are absolutely great.
this is wonderful thread

Great Idea
Hi,
Currently I'm also thinking about installing an android tablet in my car to have music, navigation, movie player, speed camera warning, etc. But the biggest problem is the sound. I want to connect tablet with car audio using jack-jack cable. Everything is fine till the AUX source is selected in car audio device, but when I switch it to Tuner or CD - the sound from tablet is cutted off, so e.g. navigation announcement are not heard.
Any suggestions for this issue?
audio rom
its a shame that there are many many roms but none fur special purposes like this.
we need a car rom

Only solution can see is to run the audio from the tablet alone. I.e. use the tablet to provide both radio tuner AND navigation. You will end up using the car system purely as an amplifier.

This would be what I would do in this situation. Or just unplug the audio cable from the tablet when using other radio options so the navigation will come through the tablet's speakers.
I want to do something similar but rather than purchase a new device I want to use my Note2. No head unit at all. The Note2 would likely be dedicated to this use and I'd get a different phone to use as, well, a phone.
For sound I was hoping I could use USB OTG to connect a USB sound card with 5.1 output but I'm not sure if this would work. I want to use the sound card instead of audio direct out of the headphone jack because that reduces my connected cables to just one (easier) and should provide at least 4 channel output which eliminates the need for another device to control volume, fader, and balance.
For radio I was going to use SDR for AM/FM (and more) via a cheap USB TV tuner.
http://sdrtouch.com/
Where I'm stuck now is that I'd like to be able to connect an iProduct (iPhone/iPod) like you can to most car radios and control/stream music from the iProduct, via the Android Note2 using USB OTG again. I cannot find how to do this but the Parrot Asteroid Smart runs Android and it seems to be able to do it so it must be possible.
http://www.parrot.com/usa/products/asteroid-range/parrot-asteroid-smart/
Any info anyone can provide regarding the sound card and iPod integration would be highly appreciated.
You can go wireless and use some AirPlay receiver for Android.
I don't know about wired solutions, the classic iPod connector has ~30 pins and some of them are used for audio and some of them are used for serial-like playlist control plus current track information.

It's just a USB to iPod cable that they use for everything else... Parrot Asteroid Smart that I linked to has it as do most modern stock head units.
Did a little more googling and it seems several companies sell android head units that support iPod.
Why don't you use a USB DAC? There are a few out there that are surround sound capable.
Out from the DAC into an eq preamp and out to your existing amplifier. The eq preamp has main volume controls as well as sub control with dedicated output.
Also there are head units out there that are just "receivers" capable of accepting a digital inputs and outputting 5.1 signal via RCA.
I installed a nexus 7 2013 in my VW, currently using Bluetooth to connect to a receiver where it the outputs to an rca input on my deck that was relocated to my glovebox. I am planning on replacing the Bluetooth adaptor with a USB DAC in order to achieve a higher quality sound.
I am currently doing a similar install in a 2010 charger, a deck will not be used however as I will be using the DAC method with an eq and output to the factory amp. I considered going the android TV box route as I have a MINIX box, but there is some work involved in getting the touchscreen to function properly as it is not set up for this out of the box.
You can purchase a double din deck from eBay (I stumbled across it a few days ago but didn't write the link down) it has a dual os system. It uses android for the car audio function and windows for the car PC function. Not sure how well it works but it got reasonable reviews.
Edit: ...and once again I answer without reading the whole thread...:silly:
Is it somehow easier to get all the various apps on the phone to output audio to a DAC than a USB sound card?

I believe when the device detects a DAC (must use an otg cable BTW) it automatically re routes all audio out the USB. You can disable automatic USB audio routing in developer settings.

That sounds easier. Thanks for the tip.
Well I can't find any information regarding the iPod integration and I've found next to nothing for DVD video and audio CD playback and radio and backup camera functionality would also take some mucking about so it looks like I'd probably be better off buying something like this:
http://www.ebay.com/itm/7-Android-4...621?pt=LH_DefaultDomain_0&hash=item2a31320af5
Which has it all sorted out already. So much for that fun idea. No idea what apps they use for all that stuff.

That unit looks slow at only dual-core. It will probably be sluggish when multi-tasking.
The main chip probably supports several I2S devices (aux in/adc, tuner/adc, DVD) and routing plus demuxing is done via linux hardware control.
The DVD player and tuner probably support the i2c or spi protocol to control seeking and other functions. This is again controllable via the linux devices.
Usually the consumer devices don't have these easily exposed and it's probably a non-trivial task to piggyback on existing hardware, assuming the needed connections are broken out on the board. As far as I can see the only Android devices with CD or DVD are the car players like above.
Another option would be to take the sound from the HDMI signal. A DVD player/tuner can be wired in parallel with an HDMI switcher. However controlling the tracks would not be easy, it would require emulating the remote with an IR transmitter.
Long story short, I'm trying to add bluetooth to my car radio (Clarion NX409). Here is the options I'm looking at.
1. Buy a 3.5mm bluetooth receiver likeTHIS and hardwire it to charge all the time and hook it up to the RCA inputs on the radio
A. CONS:
1. I won't be able to edit the equalizer on this mode (So stupid they didnt enable you to do this on AUX mode)
2. I'm pretty sure you have to turn this device on when you get in the car. This is a problem since i want to hide the device
3. I might get alternator whine since it is charging while listening to it
2. OR, my car radio supports mass storage USB device. (I can play MP3/WMA files on a flash drive). If there were a way to spoof my car radio into playing a file that is constantly being written while the bluetooth receiver receives signal/audio. For example, plug a bluetooth receiver dongle into the USB port, car radio finds one file and plays it, that file is being written at the same time it recieves signal.
#2 is just a shot in the dark. I feel like its possible, but would have to know how to program such and such and also find a bluetooth dongle that you can store a file on. I am open to suggestions and also if you feel like you can do #2, I would pay you what I would ended up spending on the bluetooth reciever, 40$
Thanks,
Does anyone have a car stereo with a USB port? If so can you elaborate on what that is like to use? I am purchasing a new unit and that feature is one I do not truly understand. A few questions I have are listed below, but feel free to add anything else you think might be useful in making this decision.
1: Does the phone charge while connected to a USB port on a stereo?
2: Can you use the file system and player controls through your stereo or do you have to control the music and other audio through the phone itself?
3: Does the audio work from all sources with a USB connection(for example phone calls or turn by turn), or will it only play music player audio?
4: If you do have access to the file system from your stereo, will it display song titles and artist info etc? How cumbersome is it do control this way?

It would be helpful to know what actual head unit you're getting. But I will try to answer most of the questions as best I can since I have a fairly new Pioneer HU.
1. Yes, but it only charges on "USB" mode, not "AC".
2. Yes and no. The Pioneer HU that I have does NOT support MTP mode (which is what Jelly Bean, and I believe ICS) uses. Basically MTP is the protocol for storage on the Galaxy Nexus. If you can find a ROM or Kernel or any way to change the mode to "Mass Storage", then you'll be able to browse the file system.
3. Only music (or whatever else is inside your MP3 file). When you connect to your HU through USB, your phone basically turns into a flash drive. From there you have to navigate to your "Music" folder and tell it what to play. The only way to do calls, navigation and music at the same time is to use Bluetooth or a 3.5mm cable with an inline mic.
4. It displays what is inside your ID3 tag inside the MP3 file. So basically, if you have all the info filled in, then yes, it will display it. As far as how cumbersome it is, it takes some getting used to, but not to bad (on Pioneer, I have no idea on any other brand).
Short answer: Unless your stereo support MTP or you can find a way to force "Mass Storage" (which I'm not familiar with a way how), your stereo will only charge your phone. It sucks, but that's the way it is.
Pioneer has the app radio which will control your phone and also allows you to use Pandora on the actual H/U. That said I have never used it nor do I plan on it as its a dual din and I am just happy using bluetooth.
I have a JVC unit that works great with my nexus running linaro aokp jelly bean. The unit is x50bt. It will not play through USB only charge. However it is Bluetooth enabled so it can play anything including you phone calls through your car stereo. I have it setup so that my phone auto connects and plays Pandora automatically. The head unit displays song title and artist and also allows u to thumb up or down using the remote conyrol. I also have playlists set up in power amp for my MP3s. The built in equalizer in power amp along with the equalizer in the head unit work well together. I have the USB cable in the rear USB port so it is hidden in my CRZ. The tiny Bluetooth adapter is in the front and does not look out of place.

Per your suggestion, I purchased the X50BT. I am not disappointed. As you said, it does not support MTP, however I have a tiny 32gb Flash Drive(about the size of the Bluetooth Dongle) inserted in the front and the audio quality is simply breathtaking. I have my phone set to auto-connect via Bluetooth, which it does seamlessly. It even connects for audio however the BT audio stream sounds terrible when compared to the USB audio from the flash drive. I don't know if that's a limitation of my phone, the technology or the unit but it hardly matters since I can fit all of my music on the USB drive anyway. I just have to use Bluetooth or the 3.5mm jack for Pandora. Thanks for the suggestion, I really love this head unit!

If you're rooted, you have to tweak the Bluetooth sound profile using voodoo or DSP manager for example (which one your kernel allows).
You could add some "gain" amp or reduce the "Mids" and raise the "Bass"..
I have a different sound presets for the:
-Phone speaker (added some mids)
-Headphones (optimized for my Sony headset)
-Blueooth (lots of bass and "Rock" setting, sound is pretty good)

I just wanted to point out that even if you found a way to force USB Mass Storage, it is unlikely that your radio would be able to read the filesystem. Most radios will only read FAT file systems, while the Nexus uses EXT3 (I think, could be 4). So Bluetooth/AUX are really your only options.

I just installed an Alpine HU, It is also does not support MTP. I really like using the Bluetooth but have found that I have to reboot my Gnex and or restart my car to get the Bluetooth to sync correctly. USB does charge but it is slow. One thing to look for is Bluetooth Parrot.

I am finding that it is more of how my HU looks at my blue tooth. Thus restart car. I am wondering if it has something to do with Android BT. My gnex has worked this way with multiple roms and BT enabled HU.

I bought a cheap stereo from Wal-Mart a Dual stereo with Bluetooth, takes a SD card, front and back inputs and satellite compatible. It has the USB plug that charges but like the others, doesn't read the memory on the phone. I stream through Bluetooth all of the time with Spotify. My son's Galaxy SIII can connect too if I turn mine off without changing anything. It was a great investment. It is a convertible and the microphone works great at 70mph with the top down. For $118 I am very happy.

I don't believe the Galaxy Nexus will work with the USB of many head units since the Nexus uses MTP instead of UMS.
Hopefully someone can come up with a UMS for the Nexus.

I think the better way would for HU to be able to connect like they do to Apple products and have MTP support.
HU
I know that JVC / Ken-wood have apps for android. Looked more like a HU controller rather then playing from android. Never tested.
I think I figured why my USB isn't connecting from the AVH 4000 NEX to my galaxy note 3 SM-N900. It's possibly due to the MTP mode. I believe if the was a mass storage mode that will work, kinda like a USB stick. I don't think the firmware in my HU is properly picking up MTP, all it does is charge the phone. You need a kennel that has UMS enable for mass storage however the international note 3 SM-N900 currently does not have such kernels. There is only 3.... To my surprise. Maybe the last time I ever go with international models again. If anyone finds away around this let me know thanks.
My car does not have USB or card reader, but aux line!.
So I decided to go cheap and buy a Vieta FM Car Transmitter and BT Handsfree unit, and I does a decent job.
Perhaps in a future I'll go for a Parrot...

...my phone is stock, not rooted. Stereo is not bluetooth-enabled, and I would prefer to stream via usb than the aux port.
-> Can anyone advise any tweaks or apps that would enable the phone's streaming audio to be played via the stereo's USB mode?

I have a similiar radio. No bluetooth but a usb on the front and an audio input on the front. As I understand it the stereo itself can't access the phone this way. It doesn't have drivers to recognize the Samsung phone. Think about it. you plug your phone into your computer by usb but you have to download and install drivers for the two to work together. Mine from the looks of it has Iphone drivers built in but nothing for android. You can probably plug a thumb drive in loaded with music and it'll play. What I do is use a stereo cable from headphone output on the phone to the audio in on the stereo. If I need to charge it I have the standard car charger for that.

Youre doing it wrong
The reason the battery is decreasing is the amount of current drawn from the device. Either the radio is not strong enough to supply the right current or the phone is recognizing it as a computer and limiting the draw to 500ma. My rough estimates show that the phone uses closer to 750ma while in use just to run. You can verify how much power it is drawing with this simple application https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free
You could try to install a kernel that allows you to override the amount of power drawn from the port. I was the first to request the feature and Ktoonsez was nice enough to implement it into his kernel. Now you can set the AC and Computer USB draw to any amount you like.
Secondly, why did you think you could play audio through USB in the first place? I guess it would be possible if the radio supports MTP but then the phone would be acting more like a USB stick and you would have to choose the files manually on the radio itself.
If you really don't want to use an Aux cable then I suggest buying a bluetooth dongle and connecting it to the rear AUX inputs on the radio. They are relatively cheap and you can install it inside the dash never to be seen again.

This is all really helpful info, thanks
Yeah, not sure why I thought I could stream via usb either, must've been mixing up the functions of that and the aux cable.
-> So I'm familiar with a bluetooth dongle that connects via usb (...think that would work properly in a car stereo too?) - but you're recommending a dongle that connects internally? Know where I'd find that for sale?
1st, my assumption is you're rooted...?
If no=Boohoo... Root or buy stereo with Bluetooth.
If yes= install this app... https://play.google.com/store/apps/details?id=com.mohammadag.samsungusbmassstorageenabler
Open it, grant it root privileges, click the "mass usb" (I think its called), and profit!
*Music must be on external card.
<-- my thank you is over there
Do you have an auxillary input option on the stereo? 3.5mm jack...
The advantage is that it's guarenteed to work.
The disadvantage is that you can't control the song selection from the stereo. You have to do it from the phone.
Also, could it be there you store the music? If it's on an external SD card I can see where that would fail. Maybe if it was on the internal memory? Remember the car stereo probably isn't real bright. If it doesn't find what it's looking for where it expects to find it, it won't keep looking.
You might have to have it stored in a specificly named directory on the phone too.

"Internally" meaning it goes inside the dash, behind the radio. Its just a bluetooth receiver with an audio output (either a headphone jack or RCA cables)
If you want listen to music over "USB" you can get certain touch screen radios that will mirror your phones display

O-for-two...<grumble-grumble> :crying:
Upgraded my factory cassette car stereo to a new one with usb port (no bluetooth), thinking I could both stream the phone's audio and charge the battery via usb.
Well, the battery's levels actually decrease when plugged in, and more to the point, the phone isn't recognized in usb mode in the stereo and quickly goes to radio mode and the phone displays the following message (please see attached screenshot)...
...my phone is stock, not rooted. Stereo is not bluetooth-enabled, and I would prefer to stream via usb than the aux port.
On the bench after testing all the functions and ready to install....

-> Can anyone advise any tweaks or apps that would enable the phone's streaming audio to be played via the stereo's USB mode?
Thanks in advance!

There is a mod that allows your phone to emulate a usb storage device that would allow you to play music stored on the phone through the stereo you installed, however there would be no controlling any of the sounds, etc via the phone. All the controlling has to come from the stereo itself. Volume, tone, selection, etc. You also need to check the format that the stereo "expects" to see in order for it to be able to function.... Such as Folder size, (files within the folder - how many) How deep the folders are allowed to be set as like in subfolders, etc. What the storage media format is able to be accessed, etc. It gets a little technical and the results are a bit disappointing in the end...
The best I can recommend is a display screen unit that supports using the phone in the USB input. I just installed a Pioneer AVH-X4600BT that works with my (GS4 rooted 4.2.2 Stock ) in my Wife's Subaru Outback. We can plug the phone's USB cable into the stereo (via a Mirrorlink add-on) and run the PHONE using the touch screen of the stereo. You'd be able to run Pandora, answer/make calls, answer/create e-mail and Texting, listen to the music on the phone, watch video that is stored on the phone or DVD's, and most important, NAVIGATION on a 7 inch screen!. All of that though, is dependent on the phone you have. As of yet, the Mirrorlink supports the iPhone, GS3, GS5, and with a hacked app in the phone, it also supports GS4. There is a free app on the market that is called Drivelink which interfaces your phone and the stereo.
You might want to research other stereo devices that have the Mirrorlink application support. I believe Sony has some, but I didn't go past the Pioneer unit. Bottom line, BE SURE TO DO THOROUGH INVESTIGATION ON WHAT YOU WANT TO DO AND THE CONNECTABILITY OF YOUR DEVICES. I know you just bought the unit recently so you just might be having to live with your setup for a while. That's o.k. though, next time you purchase something like that, you will be armed to the gills with knowledge and get something you'll really enjoy.
On my test bench after testing, and was ready to be installed....
Good Luck, and Aloha!

It's doing that because your phone uses MTP as the Media Transfer Protocol. Basically, it kind of mounts like an MP3 player or camera and the new DIN you installed doesn't know what to do with it. The real trick is to get your phone into UMS, USB Mass Storage mode. There's a UMS app in the play store, BUT you have to be rooted to use it. It basically mounts your phone like a regular old thumb drive. Do that and your new DIN will see it no problem. Only thing is, like a USB drive you'll have to navigate into your folders to play your music. This was what I threw in my car and it's been awesome!

This is all really helpful info, thanks
Yeah, not sure why I thought I could stream via usb either, must've been mixing up the functions of that and the aux cable.
-> So I'm familiar with a bluetooth dongle that connects via usb (...think that would work properly in a car stereo too?) - but you're recommending a dongle that connects internally? Know where I'd find that for sale?

I bet I know why you thought you could play audio through USB. It's because Apple products can do it. One of the things that drives me nuts is that most cars with USB ports have audio playback support for Apple devices because of Apple's dock interface that let's the docking component control and navigate the audio. Unfortunately (and it drives me crazy) Google hasn't created a similar interface for Android so there are no Android Docks. Android devices like the S4 in your car rely on on AUX to send audio. It really sucks and Google has committed to addressing it this year in the car but I don't know if they're fixing the underlying problem of a uniform audio interface in android; meaning one where you plug in a dock and it recognizes your phone and how to access your music and playlists. Again, Take a look at this if you need a quick fix. I know you were hoping your new stereo would do it, but you could easily hide this:

1st, my assumption is you're rooted...?
If no=Boohoo... Root or buy stereo with Bluetooth.
If yes= install this app... https://play.google.com/store/apps/details?id=com.mohammadag.samsungusbmassstorageenabler
Open it, grant it root privileges, click the "mass usb" (I think its called), and profit!
*Music must be on external card.
<-- my thank you is over there

I don't understand, am I missing the post where u said u did this and it didn't work?
This is what u need to do... period. If this app won't work with your rom, find an app or place in the settings to enable "mass storage". The above linked app works for me and many others.
