Mount USB To Car Head Unit - Samsung Galaxy Nexus

So, just got my GN and loaded up some music on it and synced my Play library.
Drove to work this morning without any music because the USB mount options are for Media (MTP) or Camera (PTP) which, I guess, my Pioneer head unit cannot support. Is there a way to just have it mount as USB storage? I thought that Camera option would be the "old school" USB mount but I guess not.
The phone itself is stock - I have not made any modifications to kernel or rom yet.

No. The Galaxy Nexus does not support USB mass storage mode. If your head unit can't do MTP or bluetooth, you're out of luck.
There are several threads on the topic you can search for if you want the details on why this is, but it basically comes down to the fact that the phone has no separate /sdcard storage inside - it's all one big chunk of flash memory and can't be mounted as mass storage because the phone is already using it (would be kind of like trying to plug a hard drive into two computers at once). Other phones with a real SD card or separate /sdcard storage (Nexus S) disconnect this from the phone so another device can mount it.

GN Mass Stroage / MTP

I have been very excited about the GN since it was announced. I love the big screen and the fact that it is a pure Android phone.
There has been a lot of talk about the lack of Mass Storage on the GN, but I am not sure I care. I don't really understand what happens with MTP. So I have some questions that perhaps those familiar can fill me in on.
When you plug the phone into a Windows PC, what happens?
-Can I still drag music over to the phone or do I have to use some kind of a wizard?
-I will ONLY be able to copy over music, videos and pictures correct? I can't copy other data over, for example a ROM via USB right?
- I can still copy things like ROMs over using a file manager and WiFi correct?
Thanks!

Provided that the Windows PC is Windows XP + WMP10 or above, it'll function very similarily to a normal drive, except you will just see it as "Galaxy Nexus" instead of being represented with a drive letter.
You can copy anything you desire, only PTP has a restriction of accessing the camera/picture folders.
It is said that transferring larger files or a bigger queue of files may lead to freezing or cancelled transfers, but i've personally not experienced that yet(On my Eee Pad Transformer)

Thanks! So if that is the case, why all the talk that people are disappointed that Mass Storage support is not there? If it still appears and you can still copy files over, what is the problem? Do people really want a drive letter that badly? For what? Scripting of some soft?
How does this affect mounting the phone under Linux?
With my current phone, I plug it in and since it is a mass storage device Fedora simply assigns it as a hard drive /dev/sdb for example. I can then just mount the SD card inside the phone.
Is this going to cause a major headache for me? I'm switching to a Linux phone to get away from all this Windows crap!

You are going to have to deal with all the Linux crap, including the additional software you will need to make MTP work for you.

Actually MTP is not without it's drawbacks, due to the "lack of a drive letter", or rather it being considered a physical drive, it also means that interoperability will be harder to achieve.
This would especially be true for devices like car radios with USB support, traditionally you would be able to simply connect your phone and let it serve as a USB thumb drive, the car radio could then play music from the phone, but that won't be possible due to MTP, further more since the phone is not a drive, a program that for example does not use the windows explorer as a way to copy those files would have no concept of the drive, for example, a command prompt wouldn't be able to access the drive as it has no drive mapping.
There are other pros and cons, but i think this is the one people are the most concerned about.

Google has official support for MTP on Mac, as for Linux the community already has support for it as well, i don't use either system so i can't go into more detail, i just know that the support is there

Great. Well I'm sure there will be a mod somewhere that enables mass storage.

If you're referring to a mod that enables USB Mass Storage mode on the Galaxy Nexus, there likely won't be since the storage on the Galaxy Nexus is partitioned in a completely different manner to how has been done previously on Android phones.

I'm wondering what would happen if one put an extra partition on the phone...
not going to be the first (or even 10th) to try it though!

Considering how Dan Morrill explains why the Galaxy Nexus has no USB Mass Storage support I certainly wouldn't want to try it
edit: to clarify, it probably is possible to do it on a modded ROM, I'm just saying that I wouldn't want to monkey around with that personally.

Using your own bootloader/recovery there's nothing preventing you from repartitioning the Galaxy Nexus the same way how Android systems used to be partitioned before Honeycomb, i.e. with a separate FAT32 internal partition for media storage. You just have to be aware of the tradeoffs: with a separate media partition, you have USB mass storage but you'll have to manage two separate partitions for apps and media with two separate space constraints. With a unified partition you just have one constraint, but you lose the USB mass storage capability.

Indeed..
*this* is why I got a Nexus Something not right.. wait a couple of hours and there'll be a fix on XDA..
Sorry, but the Nexus is a pile if I can't use it as a DAP source for my car audio. Is there any possible way to enable USB mass storage? This device will have far too many compromises to be even usable if mass storage isn't present.

Which built-in or OEM car infotainment systems support MTP?
Supposedly Ford cars with SYNC 1.0/2.0 support MTP. Windows Embedded Automotive 7 supports MTP, which is used in the MY2012+ MyFord/MyLincoln Touch systems, Nissan Leaf, Fiat 500, and some Kia models (may go under the "Uvo" system name). Alpine may use WEA7 at some point, maybe in a built-in or OEM nav system that might have a USB port that would work with the Galaxy Nexus, but I haven't found any model numbers yet. There have also been rumors that some upcoming cars (Tesla Model S, maybe?) will use Android for their infotainment systems, but nothing specific, and that doesn't guarantee MTP support.
One article mentioned using Bluetooth instead, but I'm not sure how that would work with the car's built-in Bluetooth. Possibly means pairing with a portable Garmin/TomTom nav device that supports Bluetooth A2DP, though higher end portable nav devices have flash storage for music files and can play music directly.
There are also several aftermarket head units that support MTP. Alpine, Sony, and Kenwood have some, I believe, and there may be others.
EDIT: As far as built-in goes, I think BMW has supported MTP devices on their stock audio systems for at least 3-4 years. I haven't looked at Audi or some of the better Japanese/Korean makes/models, but wouldn't surprise me if some of them did as well.
This is not the same.
This is USB host functionality, where GN can access external usb disk attached to it.
What we are talking here is GN attached to something an recognized as usb disk.

Well, doesn't clockworkmod recovery already allow you to repartition your storage the way you want?
And since the OS does actually support usb mass storage, it should be fairly easy to create a FAT32 partition for sd card usage. (Similar to Nexus S, which has no sd card slot but comes with 2 partitions: 1 GB internal storage apps, 15 GB for usb storage)

[HELP] Mount as USB HDD

Hey guys, so here's the situation, I need to mount my galaxy nexus as a hdd. I don't know how to do it in Jelly Bean, but I remember when I had my Nexus One, there's an option to mount the phone as an hdd.
The reason I'm trying to do this is because I have a movie stored in one of the folders on my phone, and I need it for a presentation at work, the only thing I can connect my phone to is a Roku 2 XS, which supports playing videos from a portable HDD.
Any help please
I have the latest version of Jelly Bean, completly stock and not rooted
you cant do it.
there's NO USB mass storage available on the nexus.
You can't mount the GNex as USB Mass Storage. You can only do MTP for file transfer.
wow that sucks big time
My old Nexus One was able to mount as usb mass storage, you'd think that such an advanced android phone as the Galaxy Nexus can mount that way...shame on whoever is responsible for removing that feature

its not a feature. there's no SD card. if there was an actual SD card, you could mount it has USB storage.
your nexus one has a SD card.
the omission of a SD card in preference to a unified storage has been known about for a long time.

Why? Whenever you mount the storage it's unavailable to the phone. This makes much more sense. I hated how the phone couldn't access any files on my DInc when I had it mounted and transferring files from the PC (ringtones, pics, apps, etc).

[Q] HELP: any way to enable the mass storage mode on the galaxy note 2 ?

can any one help me and suggest a method to enable the mass storage mode in my note 2 , when connected to my laptop ?
Firstly why? MTP is better when you get it working as you don' t need to unmount anything from the phone first!
Secondly, it is likely to be possible yes probably very similar to how it was hacked to work on the s3, however it only worked for external sd and caused lots of corruptions to sd cards... so it is far from perfect.
My advice would be to get used to MTP.
i was need it to let my stereo car read mp3 files i solved by installing an s3 hack that can make the extsd a mass storage unit take a look here http://forum.xda-developers.com/showthread.php?t=1711009 it worked for me i'm with omega v4 rom

I understand what you mean but. ..it becomes virtually impossible and frustrating to transfer stuff to internal memory or even external memory because it is slow. ..Very slow
External memory I can manage by taking out my card and using an adapter to plug it into my laptop card slot..
Is there a way to mount internal memory as usb mass storage? I don't mind if I have to turn my phone off or something

Did you try Airdroid?
Sent from my GT-N7100 using xda app-developers app
try Kies over wifi...
it transfer data using local connection and transfers GBs of files in some minutes definitely MUCH faster than MTP and prefer it to AirDroid, but it hasnt been working lately (last time i checked was a week or two back)
This is a problem for those like me using Ubuntu. I never managed to make MTP work on it.
Wi-Fi transfer of files can be done with X-Link, but the lack of mass storage is a nuisance.

Yes, MTP is a big problem on Ubuntu. I have tried 3 implementations of MTP protocol on 12.04 and 12.10, no dice.
i'm searching for an answer. worst thing with mtp is the fact that it hides directories from you! so you can't backup everything properly. annoying
bump! MTP is too/painfully slow. Reminds me of 1995. We need an alternative. Whoever put up this technology without due consideration and testing, before deploying it on these popular devices needs to be consider a different job.
looks like I wont be getting this phone until mass storage mode is added

Unfortunately, there is no way to enable UMS mode without rooting the phone.
I had to find a solution for my car stereo be able to read mp3 files.
I just rooted the phone and install SGS3 easy UMS ( PlayStore ). Yes its working just perfect on NoteII.
I'm using Ubuntu at work and it works like a charm as well.
Don't forget to unmount the drive in Ubuntu before unplug, and stop the service on Windows.
Also, on the UMS app, switch back to MTP before unplug, to avoid files errors ( no problem if u are just reading, ie: car stereo)

Hello,
one question - how to make two-way sync folders between my laptop and SGN2?
I always did it with GoodSync, but now it is impossible...
thx
Haha isn't this a cool icon? ---->
Gah.... I was hoping there was a way to USB mass storage on this phone. I guess I should have done more research on the phone before I bought it. I'm still in my 2 week return it period, but that's not THAT much of a deal breaker. Just really stupid... Why can't I have it all?? I mean we finally got USB host (OTG or whatever; same same) from a stock phone, only to lose USB Mass Storage! Oh the frustrations!
Dramatics aside, will a custom ROM allow something different? I'm not clear on what layer this MTP mode is operating at. I did think it was funny that it popped up as a camera type device in Windows. Right now I'm only using internal flash. Usually I want to browse pics on the phone from the PC, and in this case, if I use IrfanView to open one on the device, it copies it local and then opens it, so I can't scroll through them. Silly, and mildly frustrating. :-/
I'm going to look into some networking options to see if those work (Kies, AirDroid, maybe FTP). Actually, Dropbox might solve this particular problem for me now that I think of it.
I saw the thread for mounting external SD as USB mass storage. I take it there's no way to co-mount the internal storage as a USB mass storage device?

Well, Samsung turned off the USB Mass Storage for obvious reasons. But anyway, I can access both memories from my computers, using MS Windows.
On windows, there's no problem at all as you can manage all the files directly from explorer.
On Other systems, the problem is different. For some reasons, like with all other systems (ie car stereo or media player...), the galaxy will not be recognized because MTP needs drivers. Then, you have to use UMS and the only way to install and use it is to root the phone. But keep in mind UMS will only permit access to external memory card.
Well, if I have to transfer files from internal memory through UMS, I copy the files I need to external memory before using it..... That's not a big problem , is it ? And because your phone is rooted, you can even find a script to copy some folders automatically.
Hope I'm clear enough and it helps.

UMS, MTP and car usb inputs...

I'm really missing UMS, my car stereo usb input just cant scan all the music on my 64g card using MTP from the phone.
Just sits for ages. It worked flawlessly on my old phone, but it was using UMS.
But UMS isn't support anymore by google, thus the option was removed.
* Guess I can use real usb sticks and not use my sg4 as a usb drive.
But still trying to backup the memory card in the phone with windows, crashes explorer, MTP doesn't like the amount of files.
* Guess I can take the memory card out and put it in an adapter and put it in the slot in the PC...
I hate MTP, and I hate that the general consensus thinks its better than UMS.
I think cyanogenmod has UMS, maybe thats the answer...
sigh, one of those, its broken by design, and you suck for trying to use it, go away, we know better moments. I need a drink...

Can't get external USB to mount

I have a Joying RK3188 with Malaysk's rom.
I have a 32gb usb thumb drive plugged into one of the usb cables I have ran into my glovebox. When I plug it into either one, it won't mount and immediately says "OK to remove media". I go into settings - storage and attempt to mount it and it just says "Safe to remove media". I'm wanting to use this for music with PowerAmp.
I've searched different keywords and cannot find the solution to this.
Formatted FAT32 right? Just making sure. I use a 64gb with no problems.
I have similar experiance with xtrons td101a.which has 3 of external usb cable from back and one at front panel.And each of them can mount USB strage anytime but 3 of back USB enable to mount only one storage as "USB2".This means HU recognize
front USB as "USB1" and 3 of back USB each of them are all "USB2".There is no "USB3" exist I believe.So this is not problem it's a specification of huifei type HU.I hope you can understand my poor english
