So I am planning on getting the Infuse dock for my S3. I want to hard-wire it in my truck so it is a clean install and wires are not everywhere. My options that I see right now are to splice in a cig lighter socket to the current one or the head unit power and then just plug in the car charger to that and run the wire behind the dash up to the mount.
I am assuming the power adapter that gets plugged into the cig lighter steps the power down from the 12v+ to the 3 or 4v to charge the phone correct? Or is this built into the part of the actual dock/mount that slides into the phone? If this is built into the dock/mount I could just run a wire straight down to the fuse panel and wire it in there without having to use a cig socket and adapter.
And another quick question....if I got a new head unit with a rear USB port I could just run a longer USB cable from the dock behind the dash to the rear input. Assuming this provides power, I could charge, use MTP, and stream pandora correct? Would this also replace Bluetooth hands free calling? I guess it would just be simple to pop the phone in the dock and have all those features and not have to worry about turning Bluetooth on and off and pairing. Plus I would assume audio quality would be better via a wired connection rather than Bluetooth.
Anyone?

The dock needs a micro usb connection, which is 5 volts. You have lots of options, from just plugging a micro usb car charger into the dock and lighter socket, to opening up that car charger and wiring direct to fuse box, to wiring a new lighter socket under the dash to the fuse box then getting the little adapter that looks like a rocket that plugs into a lighter socket and gives you a usb port. Combine that with a micro usb cable and poof. I did this last setup and it works great...

Does anyone know of a good, working airline charger that I could buy that would plug into the armrest on an airline so that I can charge my A101IT?
I'd prefer one that hooks from the armrest directly to the A101IT without the need to attach and/or buy 1 or more cables to the initial airline adapter to get the A101IT to charge.
Basically, like this but without the car adapter part.
Looking to spend no more than $20 USD.
You could also get this - http://www.newmp3technology.com/mc101.htm which will work with the other part.
But don't most planes have USB ports these days so you could use this - http://www.newmp3technology.com/adc101.htm
I don't know if planes these days have USB ports in the armrest because it's been a while since I've been on one but I did happen to already buy the 2nd cable with the usb part so I could charge it through my laptop.
As far as the 1st one, I already have the car adapter for my vehicle and do not want to buy another adapter or continue to take it in and out of my vehicle to then take it on a plane and return it back to my vehicle once I'm back. So again, I am looking for one that goes directly from the Airline Adapter part in the armrest directly to the A101IT WITHOUT connecting more cables like the car adapter to it. Just 1-to-1.... if it something like that exists for airlines?
Like so: http://www.newmp3technology.com/airlineadapter-a101.htm
(without the car adapter part, just have the 3.5mm barrel connector on the other side of the airline adapter).
I've just watched this video...

If you look at the charging cable for it, it has a 3.5mm headphone jack (so that it can be plugged into the aux in on a stereo)
Is there any way to buy just this cable so we can have audio over usb? Or even a way to hack one together DIY style?
Thanks.

Have you tried plugging usb in from the charging cable to see if you can put into mass storage mode and read files like a thumb drive? I would check that first.
That would probably work but I just have never seen a cable with the 3.5mm jack built in. I don't have my atrix yet, just doing some research into different things.
Should have it by late next week

Yeah, just so there's one cable coming down for charging and audio aux. Unfortunately, I don't see a way for a stereo or processor to read the phone properly until Harman's Google Open Protocol project gets into the market.
I have the dock/cable
One cable goes into the dock which the usb on the phone plugs into.
The HP jack comes out of the other end to connect to the AUX input in the car.
There are two labels on the cable, one says not to plug directly into the phone on the mini usb end and the other says not to plug into a PC (both in pictures)
I have the car dock and the usb cable supplied with the 3.5 mm does not work as a sync cable.

It's a dock dependent cable. Great question and perhaps abthird party will step up and manufacture a micro USB charging/ audio combo cable that can be used without seperate dock. Alternatively, contact your local rocket scientist. Lol! Actually, the multimedia dock does exactly the same thing, presenting an audio out jack.

But in the multimedia dock, I would assume that audio is coming through HDMI. This dock is much different than laptop dock and multimedia dock just because it conencts with phone only over USB but still gives an audio plug at the other end.
Also, I would assume that audio streaming is built into the cable and not in the dock because cable connecting to the dock is just a USB connector.
Now if audio is flowing through USB cable, the only question is if it can be played without using accompanied 3.5 mm audio jack?
To get to bottom of this question, it would require some USB debugging expertise which I dont have. Can anyone check with devs in forum?
There is no way audio is coming through HDMI because there is no HDMI port.
The car dock does something with the atrix where the atrix turns the USB port into analogue audio out/power. It's pretty much replacing data with audio out.
It specifically says on the cable to not plug into a computer, because the wires do not go where they are normally supposed to go (since it splits)

I have no reason to believe that the multimedia dock (not to be confused with the HD dock) and the car dock are any different in how the micro USB connector interacts with the phone. One thing that we do know is that the micro USB connector on the car dock is expecting a special cable. It literally states not to connect the car dock wire directly to the phone. Anyway, the bottom line is why does it matter, the key is that Moto engineered a product that will charge and output audio using a single connector. The car dock wire has the 3.5 mm audio out. The multimedia dock has the 3.5 mm audio out on the back... All appears to be the same to me. One thing worth noting is that the multimedia dock will not interface with a PC. I read a post that described the connection type, but can't remember what it was.
Im not sure how the he dock works, but the webtop hack has sound. If the he dock is just webtop/hd sharing, then yes, its hdmi. Charging via the usb port. But I don't own those docks, only the car dock, so im not sure.

The HDMI port is for video with audio only and used for the HD dock, lap dock and webtop hack. The micro USB port is used by the HD dock and lapdock to provide USB hub like functionality to the dock as well as a mechanism for charging the phone. This USB hub like functionality is the basis for the lapdock keyboard/track pad and HD dock wired USB keyboard and mouse. A Bluetooth keyboard/mouse can be substituted I believe, connecting via the phone's built in Bluetooth. The multimedia dock and car dock do not provide computer USB type connection capabilities, and NO video capabilites, as the HDMI connection is abscent. Instead they will charge the phone AND provide connectivity for analog audio out and that is it. The webtop hack is just a way of activating HDMIfeatures that are normally only triggered in the HD dock or lapdock.
Yes... I knew all of that... just too lazy to type that...
so... that doesn't really lead us anywhere?
I don't think you can use the vehicle dock cable with the phone directly unless someone reverse engineers the car dock.

I want to connect my note 2 to my car stereo via HDMI so I bought a cheap MHL cable for galaxy S3 assuming it works on note 2 as well.
The main purpose of doing this is to see the navigation on the car stereo screen so I don't need to attach my phone on the windscreen. However, every time I connect the MHL cable the phone loses GPS signal immediately. I have tried it at home on my TV, same problem. So does anyone have a genuine adapter from samsung can help me to test if you can get GPS signal with it connected to your TV via HDMI? If it works, I may buy a "real" samsung adapter and through that cable to the trash.
Same with S3

I have exactly the same issue with an S3 - cheapo ebay MHL, as soon as I plug in GPS signal definately drops.
My cable has a standard USB plug for power, and an HDMI plug for the screen and a micro-usb for the phone. To start with I plugged the USB power end into my cheapo £0.99 USB cigaratte adapter from china. Instantly the GPS signal disappeared completely.
I have today replaced the cheap power supply with a more expensive Gifford PowerBolt cigarette USB adapter and now I get more signal, but there is definately still a drop. For instance the phone on its own will Navigate when located near my gear stick, but will not get a signal when plugged into MHL in this location, but I can navigate successfully with the phone on the dash under the windscreen with the new power supply.
I'm wondering if this supply is somewhat better than the crap from China but still too dirty.
Does anyone have any recommendations of an adapter that will give a pure power supply.
The other issue I am having here is that although my power supply can output 1 AMP which should be sufficient to support MHL, GPS, Bluetooth etc and charge the battery, the phone is not detecting this supply as AC so only using 500MA from the supply, meaning the battery drains and eventually runs out on a long journey.
I know this is due to the middle two pins on the USB side of the micro USB on the phone not being shorted, thus telling the phone it's connected to AC and to draw the higher current, my MHL cable clearly does not have these pins connected.
Does anyone know of an MHL adapter/Dock/Cable that has full USB connectivity and MHL connectivity?
Hope this sheds some light, hopefully we can get some suggestions on good quality power sources to cure the interference and a good MHL adapter with every pin connected to the phone to allow for AC power mode with MHL.

We must be using the same product. My one comes in red cable. Actually, I really like the design cos one single cable solves all issue: charge+HDMI. If I use the genuine Samsung adapter, I have to connect both HDMI cable and USB charging cable.Now I use the aluminum foil from my kitchen to wrap all three ends of the cable and it makes the GPS signal a little bit better. I have ordered some ferrite core clips from eBay hope this can solve the problem.
Stupid GPS!!

Any update on this from your end? Did the ferrite core clips work? I have found some more info that this could be caused by the fact the HDMI do signal is grounded to the external lcd display, which in turn is grounded to the cars chassis (either through wires in a harness or directly) and then the phone is also grounded to the power side of things, and because both are grounded to different points on the car this creates ground potential difference. I don't really know too much about this but am told that this will almost definitely interfere with the signal. I have been advised to ensure the lcd display and the power cigarette adapter are grounded to the same point on the car. So I have hooked up a cigarette lighter socket behind my LCD and then grounded both the LCD power and the cigarette socket to the car radio harness at the same point then plugged in the power adapter into this new socket, unfortunately this has not made a difference. The next step I am advised is to ground them directly to the car chassis to achieve a better ground connection.
The problem still could remain due to the fact the circuitry in the in the lcd may cause resistance and cause ground potential difference regardless of both the phone power and the lcd power being grounded to the same point on the car.
I am wondering if connecting the ground of the hdmi port on the lcd directly to the chassis whether this may help?
Do you understand any of this? Does it make sense. Doing my head in!!!
If your ferrite cores helped let me know or if you have found a better MHL adapter that would also be good!!

No, unfortunately the ferrite core clips don't work. I cannot find any better solution than the aluminium foil wrap now.

hi all,
I have the same issue with my S3 and MHL that I got from Samsung.
When I just connect to MHL I see instant GPS signal drop and also data GPS/LTE drop as well
Any ideas how to solve this issue?

yes, I solved this issue by replacing black 1.0 MHL with new white 2.0 MHL I got directly from Samsung.
Samsung tech told me that for 1.0 MHL it is expected to cut signal when it's in HDMI mode as TV doesn't expect any GPS
plenty of people have modded the original XOOM docks for USB host, such as here.. and here...
i also dissected the standard and speaker docks this past week, just wanted to share my observations:
standard dock:
- uses a regular charger and just passes through the ~12v to the dock charging pins
- the micro USB connection uses 200k ohms between the ID pin and ground to signal the tablet that it's in a dock
- the audio adapter circuitry (which provides the line-out) connects via the micro USB port and is powered completely via that port (not via the external charger connection)
speaker dock:
- uses a separate charger that comes with the dock, rated at 19v and 1.58 amps. the extra power is likely needed to drive the amp for the speakers
- the internal circuitry steps the voltage down only to ~13.3 volts for the tablet charging pins. interesting that they didn't need to be more precise, i guess the tablet's own internal regulators can accept a bit of a range (not just 12v)
- the micro USB ID pin to ground connection is at 200k ohms just like in the standard dock
- the audio adapter is connected via the micro USB just like in the standard dock.
- the HDMI port is completely a pass-through to the external plug on the dock, it provides no functionality to the dock circuitry
i converted the standard dock's microUSB connector to a USB OTG cable for a carputer project. of course by doing this i lost the audio adapter functionality. so i then tried to convert the audio adapter into a regular USB accessory and hook it up via the OTG cable and a powered hub (to enable me to get USB host AND still use the audio adapter). this didn't work and i'm really not sure why. it just wasn't seen at all (nothing new in the dmesg output). i at least expected to see an unrecognized accessory from dmesg if nothing else.
Hello all,
I just purchased the ONE and as part of a promotion from T-MO US they gave me a free car adapter. I would like to hardwire the car adapter to my car, but the connection cable they gave me was just a Micro-USB charging cable.
I do not want to have to dock the phone then have to insert a 3.5mm headphone cable into the top of the phone and have wires running all over the inside the car.
I can modify the bootom of the dock to accept an MHL cable instead of Micro-USB, but I need to find a product that break off MHL into USB (hardwire for charging) and 3.5mm headphone jack that I can then plug into the back of my factory stereo behind the dashboard, thus only having to dock the phone and not have to plug anything else into it.
Any suggestions on such a product?
