Quickest way to output audio from phone to headunit via USB? - Android Head-Units

I have a no-brand full android headunit running 6.xx, just wondering what the quickest way to output audio from my phone to the headunit via USB would be?

There really isn't, and if there is outs goings to be complicated and messy. USB is used to transfer data and charge. You would need to take multiple steps to transfer the music then get something to find out and something else to play it ... Unless you get something that does mirroring and it might work with USB ... Might ...assuming you have USB data ports on the hu

Search for a Zbox. It will cost you about $50 and it will allow you to connect Android phones up to V7 and any iPhone over iOS8 using CarPlay and Android Auto.

[Q] How to connect to car audio system via USB?

I wanted to know how to connect via USB to my cars audio system.
I used this tutorial: http://www.mobiletechworld.com/2010/11/18/use-your-windows-phone-7-device-as-a-portable-usb-drive/
I can now store and retrieve picture files from the phone but I still cannot play music files on my cars audio system. It seems as if the phone turns off this feature when my cars head unit tries to communicate with it via USB.
I also cannot connect via bluetooth.
I have read that some folks have been successful in implementing this feat. I really dont want to use the headphone jack because I cannot control the phones audio via my head unit. I guess I am looking to set it up legacy style like my previous phones eg iphone, nexus one, milestone etc.
Any advice would be greatly appreciated.
The portable USB 'trick' doesn't make the device a USB Mass Storage device. It's a client-side registry modification that only makes the device viewable in windows explorer (legacy mode). It's still running its communications over the proprietary MTPz zune-sync protocol. This is why after running the registry modification, you can't just plug your WP7 into another computer and have it pop up, and also why it requires the Zune software to be installed, and to sync up first for it to work.
This is also why it won't/can't work with your USB capable audio system. It has absolutely no ability to do Zune protocol sync (as far as I'm aware, Kenwood made a head unit that could, but I don't know if it works with WP7. I'd doubt it), and despite the misreporting of various sites, your WP7 is not magically now a mass storage device.
Bluetooth may or may not work. I don't know about A2DP support on either your car's head unit, or WP7, and it may be specific to the device/manufacturer as to whether this is present (I have no idea). If bluetooth doesn't work, you're pretty much **** out of luck.
Headphone jack is your best (only) option. I can't recall if the supplied headphone cable has inline media controls. If so, you could probably macguyver that into a line-in cable for your stereo and use the media controls on that. Ghetto, but workable.
wow, that really sucks.. I am liking this phone less and less...

Is the nook color capable of this?

I have a half decent sound setup in my vehicle, but I'm unhappy with my head unit, I would like to mount my nook into the dash, and use it to play audio to my head unit, which I would also store all of my music on the nook, or tether my phone's data connection for pandora/youtube/etc.
I know I can do this now as is, but the quality loss over auxiliary is less than preferred.
So my question is: Is it possible to get the audio playback through a usb cord into my head units usb port?
I can play a flash drive off of my usb port, or if I use my phone and plug it in and put the phone in storage mode I can skip through all audio files on my phone using my headunit. I would like to be able to use the music player app on the nook to select the music for an easy interface for finding my music, rather than using my headunit to seek through nothing but a random list of track numbers.
Thanks in advance.

Beyond me, have you considered bluetooth, if you are able to keep it close enough? Also there is a thread somewhere on USN pin outs, and you might find some ideas here http://forum.xda-developers.com/showthread.php?t=1294860

Unfortunately my head unit only supports bluetooth function for phone calls only.
Thanks for the link, I'll check it out.

USB stream work - help?

Hey guys,
I am currently developing my school project application, but I am kinda stuck.
I would like to connect my phone to my car through USB cable and recieve car's data, like RPMs and so.
I have the OBD cable and the reduction as well.
I have found this lib: https://github.com/pires/obd-java-api
I would like to use it, but it is intended to be used with BT.
Is there anybody who could help me achieve what I want to do? I want to know how to do pooling with USB so I can get car's data in realtime.
I can pay some little money if you wish too.
Thanks.

New apple CarPlay usb dongle for android headhunts and tablets.

The above video is my review, i have it working great with my ownice c200 headunit. the usb seems to register that to the iPhone that it is a CarPlay device. the CarPlay UI apparently is stored and sent from the iPhone its self to the usb dongle and then sent to the android app. the app then sends touch and audio commands back to the usb dongle and then to the iPhone.
i can send photos of the internals of the device to any one who wants and a link to the APK.
MOD EDIT: removed email address and mention of selling head units. XDA is not a place to make money!
great !!!

Can you send me?
New firmware update allowing the box application to work in the background.

First Step: updating the CAR PLAY USB DONGLE
Plug in the car play usb dongle on the PC, copy the "update.bin" file under the root of the dongle, no extra file folder and no any operation, just wait for 5 minutes, it will be quit automatically after updating, then pull off the USB dongle.
Second Step: Uninstall the old version ZBOX softare from the car audio, then intall the new one, then it will be ok to work.(With the new APK in the attachment and follow the manual)

The issue you are experiencing with the zbox having 'stage-fright' has to do with the power requirements of the zbox device. Some USB bus' don't provide enough power (or borderline) so functionality is intermittent. If you use a powered USB hub, that provides additional power to the USB ports, you'll have almost no issues.
I have connected a y USB adapter.
Has anyone tried one of these on a PX3 RK3166 head unit?
I have one but cant get it to work.
It connects to the apk but wont connect to the iphone.
Tried the update to firmware and apk, still no joy.
Not sure if i have a faulty dongle or it's a compatibility issue with these head units.
Alibaba seller suggested not enough power on head units usb?
I have the same problem with one of these.....
I have tried three android units now and I still can’t get them to work....
Android 4.4 it says its connect but the iPhone just shows as not found....
The other two are both 6.0.1 and the zbox just shows connecting all the time!
If any one has any help it would greatfully be received..
Or for that matter any software updates.....
Mine is showing apk: 2.1.0
Zbox versions: 2.1.0
Many thanks and kind regards
Mine works and I have a px3. I updated the device and installed the latest zbox app before I tried it. I would try swapping out cords and making sure they are certified by Apple. The only issue I have with mine is that it cannot be controlled from the steering wheel.

I use a second usb-plug and a y-cable to provide sufficient power to the device.
What do you guys do with regards to phone calls? My phone is obviously paired to the head unit via Bluetooth, so whenever I get a Call, it jumps out of CarPlay/zbox to the Stock phone interface, however the phone still transmits the audio to carplay and not via Bluetooth by default.
How any of you solved that problem?
If you are using CarPlay why do you have Bluetooth paired? Every car I've been in with CarPlay diconnects the phone from Bluetooth.

I have an Eonon GA7157 running a:
CPU: Allwinner R16 1.6GHz Cortex A7 Quad-Core
RAM: SAMSUNG DDR3, 1GB
Storage: 16GB
I have tried App and Firmware 2.x and 3.x. No joy. All I get is "Connecting" when the usb dongle and app is started. It never gets passed this "Connecting..." stage. USB devices like keyboards, mice, USB Flash drives, and even video camera work fine on this headunit. The Zbox Z1 and an OTA tuner don't work for some reason.
I did some more troubleshooting and found out the following: The dongle works perfectly on my PC running Remix. I also tried it on Samsung Table A; on this one, same symptom as the head unit, so I tried using an OTG cable and what do you know, it worked perfectly.
Therefore, I have 2 possible explanations: The headhunt's USB cable needs to be hardwire as OTG or Eonon somehow has decided to block certain type of USB devices that request data asynchronously. Why? I have not clue... I wish I could disable this flag in the OS, but I have not clue where it can be done. My headunit is rooted, so it should be possible in theory.
Hello, could you post pictures of the internals? I'm very curious what's inside the lil dongle. Also: do you still have some of the dongles? haha

This guy has done a few videos on the unit.
Hey, can someone help me to find the Zbox Z APK 3.0 to Download in English?

Best way to hotspot to the headunit

Hi everyone.
A few months ago I got a custom android unit to fit my car (Ford Falcon 2013). I'm new to the Android Headunit scene and I am not sure the best way to get my hotspot from my phone to my headunit. I'm also not sure what software my headunit is running, hoping someone can help me figure that out. I've seen terms like MTCB and pumkpin but not sure what mine is, since its a small company in Melbourne AU.
I can setup a wifi hotspot from my phone in tasker when the bluetooth connects, but was hoping there was another way so that the battery doesn't drain.
I have tried bluetooth hotspot but that doesn't seem to work as the headunit doesn't use the normal android bluetooth settings, it uses its own thing, im not sure.
USB hotspot also doesnt seem to work as it just triggers Headunit Reloaded (AA).
The other thing I was thinking was getting a cheap data plan just for the headunit, but i'm not sure if the 4G USBs will be compatible with the headunit? Never tried one on an android device before.
Worst case I can just setup a wifi hotspot through tasker, but hoping someone will have some insights for me.
Thanks in advance!
I struggled with this a bit myself when I first got an android head unit. Basically, Bluetooth or USB tethering don't work without using a third party app like PDAnet, which wasn't as seamless as I liked. Using a USB hotspot wouldn't allow you to use it directly via the USB, you'll have to connect to the hotspot over wifi as well.
It was cheaper to for me to just add more data to my cell phone plan and just hotspot through that, then getting a dedicated hotspot for the car with its own plan. Now the question is why is your phone draining while your tethering? Are you not plugging it into the USB ports on the head unit itself? The ports on the head unit don't provide enough power to charge the phone while tethering so I just use a regular cigarette lighter to charge the phone while tethering
You can try using nfc chip or sticker (on the phone holder for example)
Personally what i did is to buy a regular cell plan (all inclusive, was cheaper then "data" plan) with 2 sim cards (one for the headunit and one for my ipad)
Comnected a 4g wifi usb stick and using it wirelessly (i wish my mtce system could identify the stick as a modem) but it does the job and i can save my personal data plan by using the cars wifi
