Made mine!. what a BEEP it was to SOLDER. oh GAWD.

but it works perfect. i even created my own custom Angle connector and its so awesome. i used a 1/4w resistor though because its all i could fine, QUICKLY. it fits, but was a real beep to solder. haha.

i used 28 AWG 6FT Micro usb cable, chopped it up, and soldered the audio connector on the USB A End, and resistor on the "new" micro usb port.

Works great. was a real hassle to solder such tiny wires though. haha. well worth the trouble though. Works wonders on my note 2, getting audio, music, GPS instructions out all at the same time on top of dual screen recording live whats happening with caroo pro.

i used stereo test from the play store to test left/right. works GREAT.

Hey guys :)

Just made mine for my note 2 and is not working, all my connections are fine (check with an ohm Metet), even plug in the wall with the original charger.

What I'm I missing?

Thanks
[AT&T Samsung Galaxy S II SGH-I777] dragonfly14:
you probably messed up somewhere or are using a non samsung based custom rom.

other than that you are missing information for anyone to help. other than "I did it perfectly and checked its not working"

[AT&T Samsung Galaxy S II SGH-I777] dragonfly14:
I hope that it's not what I think you did. plug in your original charge cord. does it still charge?

if it doesnt you probably mixed up or completely went backwards and have toasted your phone explaining why it doesn't work anymore.

well that means its definitely something to do with your phone as you've confirmed your cable works.

did you try a full wipe (after doing a nandroid)

is your resistor value measured with a multimeter? i think if its not spot on it can do weird things.

Has anyone had issues with the Deal Extreme micro usb to usb & aux cable on the Galaxy S4? I would post a link to it but I am new to the forum. Or any issues with homemade versions of the cable?

I just received it today, and cannot get it to work. First I had to shave the plastic down on the micro usb connector so it would insert fully into the phone. Got charging to work, but it would never go into dock mode / output sound. I decided to take the cable apart to see if there is a resistor installed. There is a 620k 5% resistor connected to the correct pins. Could it be that the tolerance is too low on the resistor? I am concerned that maybe Samsung changed the resistor value the phone looks for to hold onto the exclusivity of dock related accessories.:confused:

I'm going to try and source a 619k 1% resistor tomorrow locally, but I may need to order the linked one in the DIY...more waiting to get this going:(

DO NOT BUY THIS ITEM - http://www.ebay.com/itm/Micro-B-USB...Phone_PDA_Cables_Adapters&hash=item5d3fc1f5df - DO NOT BUY THIS ITEM

That might be the one he was talking about. It's actually about $6.66 after shipping. It comes from China, but it comes from a reputable seller. I purchased it, and will update this thread when I get it to tell everyone how it works. Fingers crossed!

EDIT: Just received my package today (the 19th, so like 16 days after ordering it, which is good considering it came from China). First impressions: I had to buy an adapter for the 3.5mm plug, as I don't have an auxiliary port in my car, so I have to use an FM transmitter. That said, when I hook up my transmitter, the adapter, and the cable, it doesn't do audio. At least it charges. Even when I try with desktop speakers, the cable/adapter duo won't work. That isn't to say that the cable is bad, or doesn't work: it may be the adapter that is wrong or bad. I have more testing to do, but will report back here when I can get everything working. Until then, be skeptical about this cable above, but you can try it if you want to.

EDIT #2: Don't bother buying that cord. Not only does it not work, but it fell apart within a 24 hours of me getting it. The build quality alone should tell you not to buy it, let alone the fact that it doesn't work as advertised.

Car Dock audio output noise

It is not the alternator noise (sounds usually like a whine and changes with RPM) that is heard but the phone charge current superimposed on the USB ground return path. The internal phone battery circuit does not charge with a constant current but with PWM modulation. These chirps are heard when the phone is in dock mode and the audio output comes from the USB send/receive data pins. My solution was to use as audio ground not USB ground (dirty by charge currents) but USB shield.
[AT&T Samsung Galaxy S II SGH-I777] googlefreak408:
For galaxy s4 users the only way your going to get audio out is to use a 365k resistor as a home dock and just disable desk dock screen.

For Galaxy S3 - I have bought this cable and it works just perfect.

http://www.ebay.com/itm/231019843024

Fortunately, Samsung has re-enabled Cardcock mode support on SGS3 starting from XXEMC2 firmwares

I'm happy with the quality of the cable. Solid and well made for $3.50

(I have not tried audio-out since I do not need it)

In fact these cables are sold on Ebay and Alixpress by a number of sellers, but the items they are selling are all the same - they are manufactured by ChenYang Cable Adapters: http://www.connector.cn/english/ProductView.asp?ID=918&SortID=254

They have black and white designs available

Cheapest offer I have found directly from the manufacturer starts from $3.50:

http://www.aliexpress.com/item/U2-1...-music-audio-AUX-out-cable-for/818031853.html

My idea was to customize stock Brodit Holder and make car-dock mode activated automatically (I use CarHome Ultra) with TouchWiz auto rotation (unfortunately, smartdock does not enable TouchWiz rotation).

http://www.brodit.com/product.html?id=513409

Fortunately the stock cable on this holder is not hard-glued to the frame and can be easily removed (in fact it is a custom angle micro-usb cable)

I have removed the stock cable, replaced it with Cardock cable I have received. In order to make it fit I had to remove the little plastic cover of MicroUSB plug - this was enough to make it flexible enough to fit the holder in "angled" position. With a help of some tape - it was secured and fixed as tight as the original one was.

Now, having this woderfull app installed, I have Cardock app and TouchWiz rotation enabled automatically upon installation of my SGS3 into the holder.

I have also configured BT auto on/off when docked/undocked which makes mt life just perfect - no more need to think about enabling/disabling BT on the phone manually (I have stock BT handsfree in the car)

Sorry, no photos were made during the process. But it was really easy and straightforward with the mentioned above cable and stock holder.

P.S. This cable use 619kohm resisitor which activates Cardock mode. This is unfortunately not (yet?) supported on SGS4 (which supports only smartdock - 365k).

You have to enable audio output option properly in the Settings - Dock mode to make AUX audio output working. Have you tried this?
[AT&T Samsung Galaxy S II SGH-I777] lava2:
Hello Dusha999,

would it be possible you try the audio out? It would be interresting to know the output quality compared if you use a normal 3.5mm connector cable to an audio system or active speaker.

I bought a similar cable some months ago, but with an iPod connector, as that time I did not find anything with micro USB.Before removing the ipod dock connector and soldering a micor USB connector I noted that the audio out through the 3in1 cable was lower in volume. Maybe this is only related to the iPod, but would be good to know if it is not realted to a low quality of the cable build or something.

Would be great if you would find some time to check this. If not, I might get one of these to try myself anyway.

Thanks and best regards

I have also tried the aux audio out and it works just fine.

At least with my home hi-fi system.

But you have to enable Audio Output mode (external speakers) in the Dock settings to make it working

changing the BMW Y-cable

Hey I got a Mini Cooper and I would like to be able to connect my Galaxy S3 and my mother's Galaxy S2 to it via USB in order to listen to the music saved on my Phone. But as it was confirmed more than once that it is impossible to do so through a standard USB cable.

I used to be able to connect my old IPhone 3GS (using this cable provided by BMW (http ://f20.1addicts .com/forums/showthread.php?t=699811)(since I'm new I couldn't post a real link so you have to delete a couple of spaces)) and use my steering wheel controls to switch between songs, charge my phone etc.

So now since I switched to a GS3 I'd like to do the same. So do you think I would be able to replace the apple 30pin connector with a male micro USB port and keep all the functionally?

Is solvable just using hardware or would I have to add software support as well?
[AT&T Samsung Galaxy S II SGH-I777] tc3sean:
I just followed this tutorial, and dock mode works flawlessly with my sg3 running cm10.1. No extra apps, just enable daydream mode to initiate dock mode. I hardwired my charger and audio to the car, so it is truly just one cable visible. I didn't have a long enough USB cable so I just used some stranded cat5 cable! Works great, and is at least the same awg or slightly more strands than USB.

Also I accidentally switched pins 1 and 5... which was ground and 5v on the first try and my phone still works great!
[AT&T Samsung Galaxy S II SGH-I777] sunbaj:

Or you xcan buy one and cut/do not use audio aux if you don't want.

So basically a 619K Resistor between Pin 4 and 5 makes the Phone identify as if it has been docked !!! but why and how ??? What if the value of the resistor is lower than 619K
[AT&T Samsung Galaxy S II SGH-I777] masonsj:
Thank you & one suggestion.

Thank you for your post & I made my own cable with your instruction.

And, I modified your soldering as follows.

Now with the usb cable:

• Solder red wire wire to pin 1

• Solder white wire to pin 2

• Solder green wire to pin 3

• Do NOT solder the ground (black wire) yet

For Rapid Charging data+ & data- should be shorted and they are shorted in Rapid chargers.

With your instruction Normal charging is possible, but Rapid charging is not.

So I would like to suggest connect data cables like above or short 2 & 3 pin together.

If pin 2 & 3 are shorted, your phone will think he is connected to Rapid charger (i.e. > 500mA).

Thank you.
[AT&T Samsung Galaxy S II SGH-I777] HippoDan:
Not in this case. Pins 2 & 3 are the left and right audio, and it would not be good to short them together.

I believe it's been verified that in dock mode, rapid charging is automatically enabled. It certainly seems to be the case with the car charger/aux setup that I made.

Full power charge

I was looking at making one of these but then the other day read a post about original Samsung chargers.

Apparently the original Samsung chargers the Data+ and Data- pins connected to each other and if you don't have an original charger the current is limited to 350mA. (source: http://xdaforums.com/showthread.php?t=1384253)

What I want to do is make up one of these "car dock" cables but also want to achieve the full charge rate (for now my car USB adapter is 1A)

I was thinking about the idea of bridgeing the two data pins anyway and at the same time have them go to the two respective jack pins but would this actually work? I assume it would make the audio signal mono (maybe even a bit stronger?) but would it still activate full charge? Would I even get an audio signal?

Any advice?

Thanks

Justin
[AT&T Samsung Galaxy S II SGH-I777] HippoDan:
No need to join the pins. The phone already assumes that you have high speed charging when you are in a dock, so there's nothing else to do.

Of course the whole concept may be obsolete, but I did find that the cable still worked fine on my S3 with the AOKP kitkat rom.

You need a ground loop isolator. And I still need to use one even though I am now using the homebrew car dock connection. I use this one:

http://www.amazon.com/Kensington-Re...1ATQ/ref=sr_1_1?ie=UTF8&qid=1320844295&sr=8-1

Cheap and works pretty well.

As far as noise on the dock audio out.. I do hear a bit more than when I used the headphone jack to my aux input in the car. I can hear noise generated (very low static/scratchy noises) with screen updates and when the phone is doing cell data. Not much mind you.. but I can hear it. I liked the captivate better in the way it never shut off audio and never floated the outputs when no audio output is happening like the GS2 does. It's the floating that produces the noise. Wish we could keep it from doing that and would keep from hearing some thumps when the phone fires up audio.

Hope that helps.
