[Q] Note II music/charging in car adapter?

Hello everyone! I guess you can call me a "noob" on here. First post. I am currently an iphone 4 user and am going to make the switch to the Note 2. I'm really excited about it! So, i'm trying to stock up on some accessories for it before it comes (waiting for ATT). I have a 2011 Hyundai Elantra that comes with an 3.5mm/usb cord that plugs into my car ( ebay description GENUINE FACTORY IPOD CABLE FOR 2011- 2013 HYUNDAI ELANTRA) and it works great with my iphone. It charges and can play my music through the stereo system and shows the songs on my built in GPS and can change songs through my steering wheel buttons. I like the simplicity of the one cord but I know this won't work with the new Note2. I found an adapter on ebay and was wondering if this would work with the new Note 2 and my existing cable? (ebay description Apple ipad Iphone docking 30pin female to Micro usb 5p male data charge adapter) Sorry I can't post links yet. Thanks!

CableJive samDock Question

Hi,
Does anyone have this device? I would actually like to use it with my Nexus 7 on an Ipod capable car stereo but wanted to know if this utilizes the Galaxies MHL capabilities or if it is simply using usb audio?

[Q] USB Audio..

Hello guys!
I've just bought a Nexus 7 to integrate in my car dashboard. Actually I didnt had so much knowledge about it before I bought it, (I only wanted the best and I hate apple so) but I didnt thought it was junk. And that's the only thing I wanted, a non junk tablet that could play music and works as a navigator without hardware-buttons.
My old stupid Iphone 4s worked perfectly for playing and streaming sound from spotify trough a regular usb cable to my headunit, so I didnt even reflect that googles new flagship wouldnt be able to do this simple task. But it seems like it doesnt work..
I've searched for answeres but the only thing I can find is to buy a usb DAC that converts the digital audio to analog audio but then I lose the whole damn point. I want digital audio in to my headunit. And my stupid old Iphone do it great, why the **** can't google flagship do it? Feels like I have bought a extra thin rock from the stone-age.
Please tell me I'm wrong and this is possible somehow. Otherwise I gotta throw this stupid f***** sh*t tablet in the garbage as fast as ******* possibly..
Sorry for my rage.. I just feel so fooled.. I've just bought a 400$ angry birds game. :silly:

You have a couple of options:
1. Use headphone output jack from your Nexus. Hopefully your car audio headunit has an auxiliary input.
2. Bluetooth! This is what I use in my car. If your car audio headunit has bluetooth built-in, then you don't need any cables at all. Just pair your car audio to your Nexus and start playing music! If your car stereo does not have bluetooth, then you need to purchase a bluetooth car kit. These connect to an auxiliary input on your car stereo (just like #1 above). There are bluetooth kits that also stream through an FM modulator, but that should be used as a last resort as sound quality suffers materially.
I installed an Alpine bluetooth car kit and integrated it with my factory car stereo system in a 2005 Honda Accord. Since I did not get the factory CD Changer option, I had that one input open to use with the Alpine Bluetooth. I'd post a link to my YouTube video showing this, but I'm now allowed to post links yet since I'm new to this forum.
The two options listed above are the only ones I'm aware of. I'd love to hear from others if there are other options. The only drawback to both options is that you use the DAC built in the Nexus, you don't get to pass through to a better quality external DAC. The only way around that is a Slimport adapter which uses HDMI. I don't know of any car audio units that have HDMI inputs.

What you want is achievable. Nexus 7 2012 works best with Timur Kernel however Nexus 7 2013 with an AOSP build or stock with Elemental X kernel can have a USB DAC with an OTG Y cable that will simultaneously charge.
If you have Cyanogenmod you may need glitch kernel which does the same thing.
I have a HiFiMeDIY DAC and OTG Y cable (at home) but no reason I couldn't run the same thing in my car with a car charger.

I use a fiio e7 on USB and it works perfectly on cm or carbon, no extra apps or kernel required. By the way, otg works fine with Franco kernel on either Rom and hotswapping is supported. I have not yet found another rom that supports it, but I have been using just carbon for quite a while now.

Some car head decks support android USB then it would charge and do audio. Just make sure it's android compatible.
Good, then we shall fight in the shade!

Well i can tell u most of those android compatible r meant can be connect n read as a mass storage,but not as ios.
Unless someone can make a custom rom like the one for 2012 model.

Has anyone tried USB audio on 4.4 yet? I recall reading they were making some changes to USB devices (may of just been mounting drives though).

When u guys saying otg works dor aosp or some kernel ,does that mean it works with an otg y cable aswell? Like reading files from flash n keep it charge while with flash drive on?
Sorry for the thread jack op.
U and i r on the same boat,i am doing a car mount too.
I am doing a 4g lte one.

I don't have a car, I have a scooter.
Problem fixed !

So it sounds like if I have the stock rom, with the elemental X, I can do USB audio? Do I need some kind of audio manager to specify where to send the output, or would the USB dac automatically disable the on-board headphone jack?

tried PAC rom 4.3 with elemental X 1.8
no go for the DAC audio.
sound is mute no matter what i do.

I bought the HifiMeDIY DAC and am using stock 4.4.2 w/ Elemental X Kernal. I don't get any sound out of the dac. What did you have to do to enable the USB sound instead of built-in speakers?

The Nexus 7 is way better than you described it.
You have lots of options for car audio, and they all have downsides, but just to name a few:
Bluetooth (if your car has a bluetooth receiver)
Auxiliary input (if your car has one)
Slimport (you'd need an hdmi-audio converter, but it would sound great)
Wi-Fi direct (not very common for cars, though)

Bluetooth (if your car has a bluetooth receiver) - I need the bluethooth to connect to other things, like an odb adapter and so on. Edit: The bluethooth connection doesnt always connect automatic whit the cars headunit either so that's another problem.
Auxiliary input (if your car has one) - The aux output aint that great, not good enough for my 3500$ audio system in my car.
Slimport (you'd need an hdmi-audio converter, but it would sound great) - Yes the problem is that I need to convert the audio to analoge. It needs a converter and it still doesnt give my headunit digital audio.
Wi-Fi direct (not very common for cars, though)- I use wifi to get my cars 4g connection to the Nexus 7
So in my case. This is just a really expensive angry birds game (Without sound)!

[Q] car dock with USB audio and charging

Does anyone know if one exists? I would love to have a single cable in my phone to charge and for audio. Unfortunately my car stereo (Audi rnse) doesn't support Bluetooth streaming.

I really doubt this will work for your nexus 5, but a search on ebay found this to be the closest to what your asking for:
http://www.ebay.com/itm/Micro-B-USB...Phone_PDA_Cables_Adapters&hash=item5d40faf05b
If your car at least has aux output, then you can either use a usb car charger as well. plug the audio into the aux port, the usb into charging port, and then the micro usb into your phone. The ebay listing states specifically for certain phone models, nothing even close to a nexus though. But for under $10, its worth a shot.

I have a USB charger and aux port but means two wires annoyingly. Does nexus 5 support audio out via USB?
Sent from my Nexus 5 using Tapatalk

why not use a bluetooth audio adapter which connects to the AUX port if you have one, i have no wires anymore to my phone , i use the OWL Carpad Qi charger (i have some issues right now but seems like hardware issue) and i use a Belkin AirCast Car Audio Wireless Bluetooth AUX Music HandsFree Kit, i normally wanted to go with the Kinivo BTC450 Bluetooth Hands-Free Car Kit but thats no available in my country .
So i go into my car just mount the phone in the car pad were i also use a nfc tag to enable bluetooth and turn off other stuff, and start the engine, now my phone gets charged then I press the belkin and i am connected and music is playing , i also use it now as my handsfree because i am absolutely fine with the quality.

For USB audio you will need a car stereo that supports audio over USB. I suggest looking into Bluetooth. That's how I do it and I love it.

Try them out, that is what I use and I simply plug the usb cable into the GROM Audio box, then into my phone, and enjoy music from my phone and charging as well.
For the dock, I just use the InfiniApps Slyde Magnetic CD Slot Mount($25 on Amazon)

I tried with my old GSII car dock and it's not working.

Does the Grom Audio box USB cable audio streaming works with the Nexus 5? I'm considering buying it but searching around I'm not sure it works with the Nexus 5.

Nexus 7 as Head Unit help needed

Hello everyone. I am new to the site, and fairly new to car audio.
I was hoping I could get help figuring out what I need to buy so that I can setup my audio for my car,
I have a 1998 Mitsubishi Eclipse GSX with infinity sound system( Minus the stock infinity amp, and oem radio/headunit)
I want to run all new wires to each of my speakers. I was thinking I need 14gauge wire.
I want to use a Nexus 7 Tablet as my head unit.
I would like to use a wireless charger for the tablet but I don't know if that's practical. If not then I will need a solution for charging the Nexus 7.
I want the tablet to be removable. I want to be able to tune into local radio stations.
So what I am not understanding is do I need to keep my current headunit and connect the nexus tablet to it via auxilary cord?
My headunit does not have bluetooth, and it was designed for use with an iPhone.
If I keep my current headunit how will I adjust the radio station from my nexus 7. I don't really want to be pulling the tablet out each time I need to change stations.
Then my other question is, do I need to keep that headunit to use a nexus 7?
I think that keeping the headunit paired with the nexus will probably be easiest because then I know I have a receiver for radio stations, and cds.
Also I need some help deciding what amp to get, what sub, and new set of tweeters.
I think I need a 4 or 5 channel amp
A 10 or 12" sub
I dont really know much about what brands to get, if I do or don't need crossovers.
Also some sound deadening. - which to get.
This was put in by local audio shop but they screwed me over. So I want to do it right this time myself. I am new to car audio, but I am familiar will basic electrical.
This is what is installed currently.
Deck (Pioneer DEH-6300UB)
Front Door speakers (RockFord Prime Full Range 6.5" 4ohm 3-way)
Rear Speakers (Rockford Prime 6x9" 4ohm 3-way)

best thing you can do is to split your project in to smaller parts. get them done in the order you think you can do it.
i recommend you get an N7, get the Behringer UCA 202, get a DAB stick and get SDR touch working. then figured out other parts as you have the time. it will be time consuming.
research what others have done.

Thanks for the suggestions!
I picked up google nexus 7 32gb 2013 version from bestbuy.
I will look at the other items on amazon in a little bit.
If you know a good thread that describes the process to help that would be great too!

I'd recommend getting a compatible amp and linking your nexus straight to it. Also, if you have a wifi hotspot, you don't need a radio, just use tune-in radio. it has all the local channels.

Thanks for the video! Anxiously waiting to see the rest.
I decided that the wireless charging is not going to be practical seeing as the tablet basically has to be touching the pad anyways. So hard lines will be fine.
Here is list of parts I think I am needing. Let me know if it looks good.
Nexus 7 32gb 2013 edition (Have)
Double Din Dash kit for my car ( I can't seem to find a kit that is made for my car? 1998 Mitsubishi Eclipse GSX) I have a single din dash kit maybe I can modify it to work...
Right Angle Micro-B to Micro-B Female - 5 wire
Micro USB Host OTG Cable with Micro USB Power for Nexus 7 Galaxy S III & Galaxy Nexus
PowerGen 4.2Amps / 20W Dual USB Car charger Designed for Apple and Android Devices USB
StarTech.com Mountable 4 Port Rugged Industrial USB Hub (ST4200USBM)
Fosmon Snap-On Hard Rubber Protector Cover Case for Google Nexus 7 - Black
Behringer UCA202 Audio Interface
Audio
Rockford Fosgate Prime R300-4 300-Watt Multi-Channel Amplifier
Which sub (or different)
12" Rockford Fosgate P2D4-12 Punch P2 DVC 4 Ohm 12-Inch 400 Watts RMS 800 Watts Peak Subwoofer
10" Rockford Fosgate R2D4-10 Prime R2 DVC 4 Ohm 10-Inch 250 Watts RMS 500 Watts Peak Subwoofer
Tweeters:
I don't know suggestion please.
Sound Deadening :
Some cheap but reliable: Suggestions
Wiring:
Anything special I should use or just some 14gauge?
Accept for what goes to amp which I will use 4gauge
I want to make this a removable install so I can attach it when I get in the car and take it out when I get out if I want to.
Also I decided that I will keep the current headunit I have because I do not have a dedicated hot spot for wifi and my cell phone plan only allows me 2gb per month. (AT&T)
So I will need to figure out how to push my current headunit further back.
Does anyone know if there is some app that will allow me to control my current headunit through auxilary or usb from the nexus 7? All I really want to be able to control is radio station, and volume.
Also I have a plan for making the tablet removable I just don't know what would be required. I want it to be a push in push out motion. You press it in to lock in and press again to release it.
So any suggestions for what to get would be helpful.
I was looking at another site and a guy made a box out of plexiglass. That would be good. Then figure out what i need to make the push release work.
Suggestions are needed and appreciated.
If I am missing anything let me know :good:
