I recently purchased a car that has a USB interface for the radio. My wife's Iphone fully integrates with it, of course, and via the radio's interface but the Samsung only mounts as a connected drive.
I have read other thread where people were able to force their Samsung into car dock mode by modifying a USB cable. Is there anyway to just do that in software?
you misunderstand what car mode is.
Good luck! I switched back to my iPhone for this reason alone. I listen to a lot of podcasts and I couldn't get this to work via the USB interface and I don't have bluetooth on my head unit. I can't seem to get the newest update to see if that works either. Would love to know if someone has a solution that doesn't require making your own cable.
yo sleze..what model car if i may ask?
i made my own auxiliary input for my car(i know its not a big feat) with an old dsl filter a soldering gun and some resistors and capacitors.. i might be interested in creating a usb interface for my car and then maybe i can give you some insight .. big maybe
well you will never get the headunit to command the phone, android simply doesn't support anything like that. but you can get audio over USB which is triggered by shorting a couple pins through a resistor. ill have to look up that thread but there may already be a dongle or cable out there to do this. it may not be say "android carmode" but if you find the name of the USB standard that they use to trigger it you can find the appropriate cable or dongle.
isnt there a usb headset available that can stop/start music and next track functionality ..if so you could (in theory) make a usb interface that would allow the head unit or in my case steering wheel control to work similarly?
no it wont command the phone. the framework and apps don't have an interface for that. plus the headunit would need special drivers if the phone had that capability. the issue with android is too many manufacturers do things different so unless google comes out with that on a nexus and tells maunfacturers the way it needs to be implimented I don't see any hope.
there might be a way to echo the commands through adb if you have a computer in your car. but I guess you'd have to know how the music app works for that.
we All know apple has the accessories market down pretty good. even though some older accessories don't work with the newest hardware. that's the one thing apple is good for, a wide accessory market.
now if you have a Bluetooth controler and it uses the right protocol to work with thw samaung bluetooth stack then you might be able to map keys to certain functions with an app or simple configuration file editing. but as far as USB goes I don't think android is designed to host USB input devices. there is limited otg usb support on certain special galaxy s and nexus 1 and nexus s kernels but nothing native.
maybe some 3rd party root app could eventually be developed but I haven't heard of one yet.
besides all that, who knows if the head unit will know to go into audio over USB mode in the first place, even if you get the phone in that mode, will the headunit be looking for USB storage and an iPhone interface only? was it designed to accept USB audio other than an iPod interface?
well with my car BMW mad a usb interface for ipod/iphone.. i hate mac so scratch that.. i also have a usb interface(i can control radio/nav functions via carputer) that is designed to work with I-BUS (intelligent input bus) which is what some BMW's used for audio/nav integration. some newer models actually come with a usb input that was designed to work with most media players..so i thought maybe with some time/frustration/rum..i might be able to make it work..

It still to my understanding that on BMW iDrive system will have full integration with iOS. We had a 2010 5 series at home with all the bell and whistles on it, and even then it would only display song names. With my iPod we got full library options, podcast too. Android will only be able to be used as a mounted devices.

I used to have an iPhone and installed this kit http://usaspec.com/product.php?ProductID=18. After switching to android I just use a 2.5mm to RCA cable to plug in to the same unit. Not worried too much about integrating with car controls - I also use a phone mount. Does your head unit have any AUX IN connectivity? Maybe on the rear? If so just play audio through the headphone jack. There's always the lighter socket RF adapter option too, but audio quality with those things can be lame.

yeah the headphone amp on the infuse has pretty good fidelity too. the headphone Jack might not be as convenient as a single USB that also charges the phone but I'd you want to use the playlists and 3rd party apps like Pandora or Google music its the best way. audio over USB needs the dock or special cable to trigger but I don't know which headunits will support that.

hi
i have a nexus s and a volvo c30 with the multimedia package which has a usb port. With my iphone, I could just plug in the iphone in the usb and i could navigate trough the music and listen to it on my iphone trough the car's stereo.
If i put in the nexus nothing happens, it keeps trying to read the disk.
if i put on usb storage mode, it says after a while that it can't read the disk.
is there any way i can make this work or is it just not possible?
I would check out the manual or Google it. I bet the Volvo stereo only supports FAT16 or FAT32 format (i.e. USB flash thumb drive). Just a guess. Hope it works out...
Also, does it support Bluetooth? If so, see if the stereo can accept audio over bluetooth. I've got a 5-6yr old Alpine head unit that can do it, so I'm betting there's a good chance yours can.
The manual says it indeed only supports usb2 and fat partitions...
Is there any way this can be done on the nexus?
I have bluetooth, but there is no mension about being able to play music over bluetooth, phone does work and addressbook syncs, so bluetooth works as it should
I'm honestly not sure about the formatting issue. I would assume that repartitioning the phone would be a tough job to do without messing something up.
As for Bluetooth, I don't really have any experience with audio-via-BT, but I would try atleast pairing it to the car to see if you can play around with it. Go to Settings > Wireless and Networks > Bluetooth Settings. Enable Bluetooth and turn Discoverable on. Then try using your car to pair with it, or vice versa. If you manage to get it connected, I don't really know what the next step would be, since I've never had a stereo that supported it without paying $200 for an adapter.
I would just play around with the bluetooth stuff and see if you can get it running. Since I'm not familiar with Volvo car stereo systems, I don't know if it really supports playback, or just phone calls. See if there's an input in the menu (ie CD, FM, AM, AUX, etc) called BT Audio, or something like that. 3rd party head units typically have this input if they support it, similar to the AUX input option. I'll see if I can find a generic guide for it in the meantime.
What year is your C30?
Good luck
So it looks like your car does NOT support the audio via Bluetooth protocol, known as A2DP. I found a great resource for your car that you should check out, called C30 World. From there I found a thread on this, where people say it doesn't support it, and that your best bet is to use the aux input jack in the center console. Unfortunately, it also looks like that jack is disabled if you have the Bluetooth package installed.
My advice is for you to post on the C30 World forums and ask for some help. I'm sure there's some very knowledgeable people over there that can help you.
thanks man
I think I will just put a usb splitter in there and use a thumb drive in the usb with my music and use the phone as a phone on bluetooth and still have the option to charge my phone
Try using the BT adapter that I use. Been using viseeousa 2000 plugged to my USB port. Flawlessly stream music wireless. Plug and play device and works with android for bluetooth streaming.
Hello,
I have really no idea if this is possible, how hard this could be to do and what it can require but :
1 - Would it be possible when I plug my phone on my car radio with USB to control the music with my phone instead of the radio itself ?
2 - Would it be possible to deport the sounds (calls, applications etc) on the car speakers ?
Let me know if I'm not very clear
PS : please don't answer something like "use a jack-jack cable"
Thanks !
From what I get, you want to "stream" audio through the USB port. I don't know why would you want that and the jack-jack cable is not good (maybe you have a USB port on you car stereo but no line in) but as far as I know it would take A lot of modifications (stereo and phone) to make it work.
So, theoretically it is possible, practically I don't think someone will ever make it possible.
Im pretty sure it would be impossible to control the car radio with the phone via usb. There might be some kind of solution using IR, but I don't know how that'd interface with the Droid. Most aftermarket decks allow for a wired remote on the back (looks like a headphone Jack). I've used it with a steering wheel interface adapter and it worked well, so there is a possibility that a custom usb cable could be made, but would also require a custom app written for the Droid to output the signals through the usb.
On streaming radio via usb, I don't think that's possible either, bc the uusb on the deck is looking for files to read on a mounted drive.
If you happen to have an incredible, you can get the tv-out cable and make a shorting pin on the video output. This makes the phone think it's connected to a TV, and will then stream Pandora, music, Google navigation, etc through the usb. If you do this with your aftermarket radio, you'll need an aux input and an rca to 3.5mm cable unless you already have RCA.
Hope this helps!
Thank you for answers! I was asking that because I remember when I had an iPhone, I was able to play, pause, forward the music from my iPhone. I will try to use the aux-in (I have a little Pioneer DEH-3200UB).
Thank again !
That's because both the head unit and the iPhone know a common language and communicate.
Sadly, I don't think there's anything like that outside Apple.
It is called Ipod ready. That could be emulated in Android, would be another bite out of the apple,s ass.
I have a JVC radio that works with an iPhone. Is there any SW that would allow it to work with a android?
This is the second thread you have started on the same subject. What are you expecting to do with it? As mentioned before if your phone is in disk drive mode you should be able to play mp3 files from the card. Have you tried that? Works fine on my kenwood like that.
thanks
I was actually hopping to be able to pump out audio like phone calls etc.. The iPhone can can do it. I thought the other post was removed becaues I put it in the wrong section.
My kenwood does both. But it is actually done by bluetooth. There are 2 channels, phone and AD2P that my headunit has settings for. I myself have never heard of using USB for this phone. I don't think the micro usb port is capable of handling that. If you expect your headunit to handle calls it will either have to be done by bluetooth or by auxillary headphone cable. What way are you trying to make the connection? What make and model of headunit do you have in your car?
You are correct. I was to cheap to pay the extra $ for the BT. I put a spliter on the AUX port and all works. Just had to hide a few cables. The reason I can not use BT is, I use SKYPE for long conf calls. IT works great but it does not pump out audio out of BT.
I connect one side to my XM portable and the other to the audio port on the phone. Seems to be working ok. I get a little feedback from Phone when it is plugged in to a power source. I am working on a fix for that.
I know similar topics have been talked about before, but I still don't have the information I need to come to any sort of conclusion, so here is my situation.
I have a Nexus S 4G with unrooted, unlocked, stock Jelly Bean on it and I don't want to root my phone. I would like to purchase a head unit for my car and be able to plug my phone into said head unit in my car via usb in order to charge my phone and play music (i.e. Pandora) at the same time. It sounds like in order to accomplish this the head unit requires a certain protocol MSC or MTP maybe, I don't really know. So does anyone have any information on how I can possibly make this work or maybe some information to lead me in the right direction. Google makes this sound so easy, but apparently it is far from it.
Thanks,
Dave
On my older galaxy 3 i5800 i could just plug in USB on phone and in car stereo, it asks to mount(like on PC), and phone was charging, also car stereo recognized my music, it played. So i think it only depends on radio options.

sbdave, the head unit would need to support MTP (Media Transfer Protocol) which is a new MS protocol. The pre-ICS (android 4.0) version of the OS supported MSC (which made the phone look like a normal USB drive). Most car stereos with a USB jack should understand the old protocol. It seems very few support the new one. Very annoying to me. Google wants to say that MTP is a better solution since it allows simultaneous access to the files while syncing and "just" requires some additional drivers. But how do you add drivers to a head unit? Seems like short-sighted thinking to me. Hopefully we'll get a better answer via XDA or via Google in a future OS update. Seems like it should be an option to use one or the other (like they allow MTP and PTP now).
I've tried to use the SGS3 Easy UMS app for my car stereo (Infiniti G Sedan), but to no avail. Still looking for a solution.

Hi,
I run a car audio firm, we have a PX5-based unit a client ordered.. The MCU version is "MTCD_WWW_V2.54b_2" .. Our goal is USB audio working proper, among a few other things (better interface if possible, better apps, better SQ stuff)
I haven't seen a "www" mcu anywhere? It's sold as an EONON GA7150A..
Anyone know anything about this MCU? If it's compatible with any others or anything like that? I definitely would like to root it, update the ROM to something better, get rid of the "Windows Mobile" part of it which was, IIRC, advertised as the ability to 'boot' between Android and Windows but is actually just a different interface theme from the home screen.. Also want to do whatever we can for sound quality and smooth experience.
I should note that, as a car audio company (in Canada), we are seriously considering producing our own Android units.. likely 'producing' would consist of getting units like a px5, branding them and primarily, having a SOLID software system built for automotive use. I think a lot of these units are a great start and are ALMOST there for a lot of things but..some of the interface stuff is rushed, not translated great, etc.
What I'd like to see is an Android unit, priced like these ones usually are, but with *really* good class A interfaces. The kind of experience you'd expect on a Samsung phone or a Pioneer headunit. I personally have been using my Samsung Tab S 8.4" in my car as my 'head unit' (paired with a Pioneer single din for a hardware volume knob and some easy control) for along time and I would not want to ever go back.
Here's a short video of the interface and version info..
My eventual goal is getting USB audio working decently. It does work for most Android apps but the volume control only controls the internal audio chip, and the radio app routes through the internal audio chip as well.. I assume perhaps other sources like DVD and line-in would as well, I haven't verified but I will pretty quick here. I plan on making another video showing what works/what doesn't/how it works.
I'm hoping for a software only solution but am happy to hack the hardware if needed. I'm using a Behringer UCA-222 as a "DAC" (same as 202 but red in color) but won't actually be using the DAC in it but only it's optical output into an Audison Bit 8.9 DSP/Amplifier.
There's the possibility of routing the px5's audio output RCA's to the Behringer's Input and 'monitoring' that input to the optical output via software but that doesn't solve the fact the volume control does nothing for apps when using the USB.. Eg, youtube plays through USB/optical fine but volume control doesn't change the volume..Radio plays through the px5's audio chip and volume control controls that, and shows on screen.. I could force everything to play thru the px5 audio chip and then monitor it to optical but that defeats the purpose of what I'm trying to do completely (full digital audio to the amplifier).
I'm willing to sacrifice some sources re-routed like that though, eg, the radio would be fine as it already sounds ****. Aux in also doesn't sound great usually and won't be used in this car anyway. DVD would be nice to have optical out as well but
I'm currently still searching for a schematic/block diagram for these devices, this would probably answer a lot of my questions like.. I'm curious whether audio from any of the other onboard devices (radio, dvd, aux in) go through Android at all or whether they're directly sourced to the output chip.
If it's the latter - that sucks - but I wouldn't be surprised. I have read the thread about the hardware hack to allow android control of the audio chip but I don't see this giving me the functionality I need. If it is wired like this, and I can get the other components (eg. radio chip) to output their audio to Android, digitally somehow and have Android push it to the USB audio device that'd be cool.
Is no one else using a USB dac on any of these units? I have many years experience coding, hacking, electronic engineering, tinkering, etc. including Android but I haven't done many of these Android Head Units.. A lot of times we use tablets instead! But this client wanted OEM look..so we thought we'd give it a shot.
The difference between the audio quality from the internal DAC and the USB audio device's optical routed directly to the DSP (digital to the power amp) is definitely noticeable, even with there being very little noise picked up in our interconnects.

tha same question (#1956) i read in this thread https://forum.xda-developers.com/an...-head-unit-discussion-thread-t3573881/page196
it should be KLD (klyde), you can read the answer in post #1959
Thanks for the pointer.
Hi,
I uses the newsmy carpad since 2 yrs with android box with wince interface and same issue of radio, bt and dvd being analog while the android side of things is 100% digital output via the included hdmi.
I put aside my alpine pxa-h900 and installed the helix dsp pro with auto switching of input with priority on digital input and use internet radio apps, android bt apps and plugged in an usb portable drive for dvd/cd.
Cheers.
