My aim was to make a desktop dock that has audio out. No need to hook up the headphone jack to the top of the phone. My other aim was to get it working on my S3 and my Wife's S2 (Epic 4G Touch to be precise).
A lot of the info I used came from http://cleanimport.xda/index.php?threads/1754102/
Parts:
I used the ZENiS desktop dock http://www.ebay.com/itm/110893901462 Paid for it on July 31, it arrived Aug 9. I actually bought two of them because I'm making two of these docks.
I wanted to get going on making the dock so instead of waiting for my local *REAL* electronics store to open, I ran over to radio shack and got a resistor multi-pack http://www.radioshack.com/product/index.jsp?productId=2062303 Great thing about resistors is you run them in series and they just add up.
While at Radio Shack I also grabbed a two pack of stereo plugs http://www.radioshack.com/product/index.jsp?productId=2103452 Big win - these can be flush mounted and make the whole thing look professional-ish
A little bit of wire. I yoinked a couple inches of CAT5e from a spool and pulled out some individual wires so I could hook up the audio plug.
Multimeter. I think I got the one I used free with a coupon http://www.harborfreight.com/7-function-multimeter-98025.html Couldn't find my auto-ranging one. The multimeter is so you can make sure you're getting the right resistance.
1/4 inch drill bit. For the audio plug hole.
Soldering iron and solder.
To start off I opened up the dock and found that indeed it was perfect for this: lots of empty space, exposed solder points, conveniently labelled pins. Perfect. Now using my multimeter I went through the resistors in the pack and put together a combination that came *really* close to the 365k ohm needed to trigger desktop dock mode. While at it I also made one that's 619k ohm so I can make one of these http://cleanimport.xda/index.php?threads/1321491/.

Car dock resistors on the top (4) desktop dock resistors on the bottom (3).

I did quite a bit of testing to make sure I was getting the right pins, right resistance etc... In the end you simply solder one lead of the resistors to pin 5 (the ZENiS pin labels are accurate) and the other to pin 4. You can do it on either of the little boards. I chose to do the resistors on one board and the audio on the other. The "tip" on a stereo connector is left, the middle is right and the bottom is ground.

The 1/4 inch hole I drilled in the casing. The audio plugs have a thing you can screw off then on to hold it very tightly in place. Works perfect.

My Galaxy S3 (with extended battery and in a case for the extended battery) fits perfectly. It also fits with the normal battery/back/case. My Wife's S2/E4GT also fits... if she takes off her case. The E4GT is wider than a normal S2. I guess my next modification is to widen the hole just a tiny bit so hers will fit in the case.

Front view. The orange arrows are pointing to a little on-screen button that switches the phone between audio out over the dock and audio out over the phone's speakers. I'm assuming that in the latter it would go out over the normal headphone jack if I had something plugged into that.
As noted on http://cleanimport.xda/index.php?threads/1321491/ you can also change the audio output mode in Settings > Dock Settings > Audio output mode
Thanks for the guide. I've already added a resistor to my zenis dock for dock mode, but might add an audio port now as well
I just bought a couple of 500K multi turn pots and tuned one to 365 k ohms
As a fairly cheap alternative for peeps who cannot be bothered modding, I received one of these docks the other day, which already has audio out and dock mode:
http://www.ebay.co.uk/itm/120948670614?
man, I looked for something like that for *weeks*!
you're not the only one, lol
if i had seen these docks first, i would not have purchased the zenis one
i prefer it to the zenis one too as there are no sides to rub on the cases
i ended up filing the sides of the slot on the zenis dock because of the rubbing.
i was using a case similar to the rock ones and noticed the coating had worn off one of the sides right where it was making contact with the dock.

I installed the car dock app from the nexus on my desire a while ago. Today as I was going out I plugged my desire into my 9.99 mobile fun car charger / holder, like normal. However this time I didn't plug the micro USB in enough and a notification appear that said it had been connected to a car dock and it launched the car dock app and started charging.
I thought that the nexus one had metal terminals that told it when it was plugged into the home dock or car dock. I am wondering if the desire has something in the micro USB port that has the ability to do the same.
Can you get it to do it again??
It might be detecting something on the ID pin on the micro usb, if it is we may be able to modify chargers to enable dock mode
On the droid, it's simply a magnet in the car dock that tells the phone where it is, maybe it's the same here?
Nope, tested with a magnet. As the OP said it started when he plugged the charger in its more than likely the ID pin. We just need to find what the trigger was on the ID pin.
I can pretty much get it to do it on demand yes.
I saw it pop up while I was driving and then stopped to see if I could get it to do it again. Wiggled the usb a bit and sure enough the notification came up.
I suspect from some things I've read that HTC are releasing a dock for the Desire, I would hope that this notification message goes some way to confirming this.
http://www.mobilefun.co.uk/trailblazer-universal-car-charger-and-holder-p22954.htm >> This is the charger if any one is interested.
I'll try and get a screenshot some time over the weekend too.
Which cable are you using to connect from the charger to the desire?
The standard desire cable or one that comes with the car charger?
Can you get the notification with the standard cable too?
(sorry for the amount of Q's but i'm interested in getting this working for my phone too, and i'm sure others will be aswell!)
Hi, this is an adjacent-related post, for those seeking a car dock. I like how the dock illustrated in this thread is a general purpose car mount vs. all the "customized for one particular phone" types which I think are overkill and not very versatile.
The one you show here is neat because it's attached right to the cigarette plug.

But depending on your car's interior layout, that could place your device really far from your line of sight... especially if you want to use the Desire for google maps or turn by turn directions.
I just want to show another example of a different type of auto mount, though there are hundreds of them. In USA, in state of California, we are prohibited from having those windshield mounts that use a suction to attach the phone holder. So a variety of Dashboard Mounts emerged. This, to me, is the best. It is a bit more expensive than others, but to me the value is there in total functionality and versatility....
The method of attachment is this weighted "plate", and it attaches to your dash by way of strong double sided tape or strong velcro. The weight is focused on the back side of the platform. The pltform is shiny smooth like glass, but plastic, and a suction mount attaches to it, and it is super strong, does not come apart, unless you release it to reposition.
The arms adjust in various ways and a swivel head allows you to angle the device so that it optimally faces you at the correct height and angle so there's no reflection.
It is Universal, so it'll mount just about any smartphone, and it's bottom "feet" slide either side to account for connector locations. The gripper is strong, but soft on the phone, and has minimal side contact, thus enabling volume controls to be accessed. And the whole thing rotates to horizontal positioning with a twist, while you're driving, and it's rock solid, nothing to unscrew, it just is designed really well so that it can be easily adjusted from vertical to horizontal display position.
I am just saying all this because I have used this same mount for my T-Mobile Wing, my HTC Hero, and now my HTC Desire, and all have worked perfectly and flawlessly, with total positioning control.
To me there are times and places where getting cheapest of anything is a good call. But when you envision yourself driving, and using google maps, or the phone, of switching music to next song, or, dare I say it, viewing an incoming SMS (not sending one), you cannot take your eye off the road not even for a split second. To me this is an example of where an extra $10 or extra $15 is well worth the cost of your life -- to give you the full extended capability of using your DESIRE in the car... where some of us spend a lot of time.
So, here are some pictures -- from 2 years ago with my WING... so, just to emphasize, it's constructed well too, and will last many years and not lose its rigidity of placing the phone exactly where you want it. That was important to me.
**
It looks like it is too expensive to ship these internationally from USA, but maybe you can find similar types of dash mounts in Europe.
The USA accessory provider is Arkon - here: http://www.arkon.com/iPhone_Car_Mount.php
hope this is of use
It's the ID pin that needs to be connected to the ground pin as indicated here:

This is my variation of a 3 pin pogo charging car dock.
I noticed the spacing of the SD sliding contact prongs from an old multicard reader were very close to the spacing of our 3 pins on the Gnex.
So I took it apart, pryed off the reader, and bent the prongs up slightly to make contact. I filed off as much extra plastic as possible. I snipped & striped a USB cable and soldered the red and black wires to the respective prongs.
Im in Norway, so I didn't have access to a VZW dumb dock to make this nice and clean. Instead I used a universal car mount to clamp down on the bottom half of a clamshell gnex case for repeatable contact. I put an NFC tag in the mount to trigger NFC Retag app to launch Torque app and enable bluetooth communication with the ELM 327 ODB2 bluetooth transmitter. These are cheap, and I highly recommend them to anyone interested in car tuning.
My next step is to flash the full amp pogo charging kernel, and actually mount this in the car when my wife gets back with it.

A shout out to elleshoo for the inspiration. Geaux Tigers!
ok, reuploaded pictures that fit on the screen now.
Nice, this looks simple enough. I'll have to try this out with my dock.
If you are rooted you can charge much faster than the default 500amp limit on the pogo pins if you use a kernel with chads fast charge mod(like Franco kernel)

Definitely on my to do list. Right after mounting in the car and educating myself on flashing kernels...
Sent from my Galaxy Nexus using XDA
Nice mod! And Geaux Tigers! I'm actually attending LSU as an undergrad right now!
Friction fit mounted to the swivel AC vents using an IKEA L bracket cover.
This allows easy reorientation at the cost of 1 blocked vent.
Running off a kensington usb plug with D+D- soldered.
Sorry for bad pics, my good camera was at home.
Gonna rode test on the drive home today, I know all the parts work seperate, so it should work together.
Just a little worried about the vibration pivoting the vent b/c phone is not perfectly balanced.

Got the force charge Franco Kernel going, and confirmed it in the pogo charger.
It takes few seconds to recognize its docked now, but it does go full AC.

What case did you use for this setup?

What case did you use for this setup?
Click to expand...
Click to collapse
Its a crappy rocketfish from bestbuy, I linked to it in first post. but I wouldn't recommend using it as a case, its nearly impossible to get off and leaves weird marks.
Here is the charge SS from my drive. I did get a batt lvl increase with blue tooth, gps, syncs and light browsing in use. So it works.
Did you ever get that fast charge working thru the pogo pins?
Yes, it worked beautifully on the fast charge kernel from faux and Franco. Im m the JB builds now , waiting for that feature again. It makes a big difference.
Hi All,
As Promised I am putting a little a guide here.
Any Suggestion, Question, curse words keep in Thread only.
This MOD is not hard anyway. So here we go.
Sometimes ago I posted THIS, Its a nice little Dock for about $7.
Only Down side is it dosent do MHL or USB OTG. The Reason is pin4 and pin5 are shorted together. But unfortunately there is no way just to use one extra wire and solder it a two ends.
So I boutht THIS, Its true Micro USB cable Extension for about $5.
** You can use this Guide to MOD any DOCK to make it work with your MHL or USB OTG cable.
All You have to do is, Open the Dock (There are 6 screws in the bottom of Dock) take the existing micro USB Male to Female extension out and replace it with the Motorola SKN6258.
I have used THIS dock for this tutorial. But you can MOD almost any Dock this way.
1. Unscrew the Dock from bottom. To do that you have to peel off the Rubber Pad stick to the bottom. Do it little Slowly so you can stick back the Rubber Pad.

2. Take the 3 pieces apart and take off the Micro USB male to female part. Which is almost useless. And also remove the part shown in Circle.
3. Take the Bottom piece and using Knife cut the Groves as Shown for the Back Female Micro USB Connector.
4. Now Take the Motorola Micro USB Extension Cable and remove the Protective Plastic Ends.
To do this Cut along the line where two part are stick together. Please refer to the pics below.
And also remove the Black outer cover around the wires. You can do this later too but this gives more flexibility while working.
5.This is the ONLY HARD PART. Be very careful and remove the WHITE plastic part around Female USB connector PCB covering the wires soldered to PCB. Please be Very patient
while doing this. Use the sharper blade(The Sharper the Safer). Removing all the plastic really helps putting it in place with bottom of the Dock.
Also as shown in the pictures, trim the plastic Under and on Both Sides of Female Micro USB Connector so it fits perfect in the place.(See pictures)
Otherwise it will not align with bottom edge.
6. Be little Extra Careful. As you can see in Pic 1 our new Male Connector is thicker and little shorter compare to the original Connector came with Dock.
So Using pliers we are going to take the Metal Housing around the Male Micro USB. This will lessen the thickness of the end so we can slide it easily
into existing housing without further modifications.
7. Cut some rubber pads to keep things in place. Use the two tiny pieces as shown in picture to place it around Male Micro USB Connector.
8. We almost there. Now as show in pic below you have to make another cut to make space for Male connector to fit right. Also Cut a little piece of rubber pad
to put in that groove to give cushion as shown. Also remove the little T like plastic under the tiny female connector Cover,
9. Put Everything in place and Carefully close the dock. Put couple of screws and check to see everything works as it should.
10. In my case I had to open the Dock again and trim the Front Part of Female Micro USB connector. Because if you have MHL or Micro USB cable with short length Connector
it dosent stay connected in the Dock. And this way removing unnecessary plastic housing, you can connect the cables firmly. Refer to pics below for better understanding.
The Only Reason Stock Dock dosent work is pin4 and pin5 are shorted together.
And there is no way to use an extra wire because they are shortened right on the tiny PCB attached to both the Ends.
Enjoy your New MHL and USB OTG compatible Dock.
the guide is ready to go guys.
i bought this docks from the deal you posted. opened it and was thinking about how to make things work. so thank you so much for this guide.
how long dose it take to get motorola micro usb cable?
So, you have a shiny new Galaxy S3 and you know that you're prone to dropping it into caves, diving into oceans with it in your pocket, or running it over with your tank, so like any smart individual you opted to buy yourself a super protective case like Otterbox Defender or similar. Problem is now you've just taken out the possibility of placing it in a charging cradle, or some sort of desktop holding device, right? Not Anymore!

With a few simple and cheap items, you can make yourself one that doesn't look like a 7 year old kid put it together during arts and crafts!
Here's a list of what you'll need, starting from most expensive to possibly free if your boss isn't looking
Logitech MX Revolution Mouse - you only need the charging cradle, but it'll be tough finding just the cradle without this fantastic Wiltron recommended mouse - eBay average pricing at time of posting was about $15-30 dollars for the mouse and cradle. We're going to be removing the guts of the cradle so the mouse wont be able to be charged any more after this.
USB Cable - The same one that came with your phone or an aftermarket one. Should have a good plastic head on it for stability, but the stock cable is fine too (that's what I'm using).
Tools - Drill, Screwdriver (+), Knife, Hot Glue or epoxy if you're fancy
(Optional) Expanding non-flammable foaming insulation - this is only for stability and additional weight, and is purely optional. I used it in one of the two cradles I made.
Once we've pilfered the office supply cabinet, it's time to get to work. Start by turning it over and peeling off the warning label and rubber feet. Save the little feet thingies as you'll need them later. There should be one or more screws to remove. My home cradle had 4 in a box shape, but the one I have at work only had one screw in the center. Once removed, hollow out the guts and kick them in a stylish fashion as you'll no longer need them. Seen in red below, push out that separator plate as that's what you'll be working with for drilling and gluing. Ignore the green part for now, that comes later.
You'll want to either stick the metal portion of the USB cable through a small drilled hole (or cut hole with the knife, depending on how badass you are), or if your case is substantially large, put a portion of the plastic housing around the USB head through a larger drilled (or cut) hole.
Once you've tested the seating of your phone with the position of the cable so that it will charge when seated, glue it in place in the red plate, and re-seat it into the cradle. Glue that plate in if it's loose. When the glue is dried, if you've opted to use the expanding foam, get foaming. Cut/file away excess foam, and then re-seal the bottom plate after 24 hours (so the foam is set and has stopped expanding).
Now, remember that green line in the image above? You can leave that as is, or file it down. I left it as is and it causes no ill effects. A little balancing game is required if I want to "dock" it in portrait mode, but landscape mode is fine (abet unable to charge in this fashion).
It does work though

This is a review of Monoprice Car Mount Cradle with car charger for Note 2: http://www.monoprice.com/Product/Index?p_id=10259
Let me start first by mentioning this is Monoprice branded accessory. As soon as you take a closer look you will realize this is actually KiDiGi Car Mount Cradle with a much better car charger in a more attractive packaging and only for HALF of the price of the original KiDiGi. Yep, its only $23 for the whole package including 1A Monoprice coiled car charger with LED light. It looks like Monoprice is branching out in their product catalog and now you can take advantage of a deep discount offered to us as part of their volume purchases.
For those not familiar with original KiDiGi cradle, it offers a unique mount where you slide your phone in landscape position and hold it in place with a secure spring loaded flip latch at the top. The cutout on the back of the mount opens a view to your camera and a flash for those who like to use it as dashboard cam. Also, it has 90degree micro-usb connector built into the mount for easier charging of the phone. The main charging cable from your car outlet goes into the back of the mount where there is micro-usb port which then internally connects to that external charging cable with that angled connector. Although not rated at full 2A, a provided 1A charger/cable should be adequate to power up and to charge your phone during long trips. The mount cradle is connected to an adjustable mounting arm with a suction cup. With a universal ball joint connection you can rotate it 360 degrees, which also makes it compatible with other types of mounting arms that have receptacle for ball joint. Also, the mounting arm has a joint nut to adjust the angle of the arm for a further fine-tuning of cradle position. Unfortunately, the suction cup is a regular non-sticky material which means you can use it on a glass or a smooth flat surface. Most of the other car mount manufacturers switched to sticky suction cup to allow better attachment to textured surface. To compensate for that, you get a disk with a sticky 3M side to position on your dashboard surface, or as an alternative you can use any other mounting arm with a sticky suction cup but you need to find one that has a receptacle rather then ball part.
Now here is a few very important points. Even so the box says support of Car Mode, Note 2 doesn't support that. Also, its a bit misleading that product description says it support Note 2 with and without a case. There is a spacer insert which could be removed. In theory once you remove it you should be able to insert Note 2 with a case. Unfortunate it will not work with anything as thick as Defender or Extended battery case, it will not even work with something like UAG or thin Case-Mate Tough cases, and it did not work for me even with thin TPU case. Maybe it could work with something like ultra thin air case from Spigen, but I don't have one to test it out. But it works well with a naked Note 2 and supplied insert.
Overall, its a good value considering what you are getting, but you have to be aware that you will not be able to use Note 2 in the case and also with included suction cup have to mount it only to a flat/smooth surface. Other then these limitations which might be a deal breaker for some, this is a solid car mount with a quality built and unique design.
Here are the pictures.
