Official Vehicle Dock Kit

Hi all.
Just took delivery of my dock kit, and it's very nice. Well built, but whether its worth £35 quid is another story.
Anyway, that aside...
When the default "Driving Menu" is enabled, is there a way to change it, especially to use CoPilot instead of Google navigation?
I have had a quick search in this section to see if anyone else asked the same question.

Im in the same boat. It would be nice if someone could do a workaround. Nice bit of kit for the price.

How do you get audio to come out of the rear connector. I plugged my 3.5mm cable into the socket and the sound still comes out the speaker!
Have you tried it?

Yep! I should have read the booklet, it did tell me in there ;-)
RTFM!

I struggle to take the phone out cleanly using on hand - always hit the power button. Dock mode seems pretty poor to me, seems to get all voice activated with road noise - is the google one any better? (we have a samsung 'special', I think?)

Another thing I've noticed is the terrible engine whine from the loudspeakers when its charging.
Now I tried headphone out socket too, and the same problem occurs.
To me it's a lovely piece of kit, but if you have it connect via Aux then u need to listen to the whinning noise from the charging.

Anyone conquered the noise suppression from an in car charger? It's doing my head in!

have you checked it's not your car? Will try and remember to test if mine does this...

i also have the whining problem when charging. after some investigation, it appears to be caused by poor connections. in my case i suspect the head unit, as i didn't connect the rod at the back to the car frame with the bolt and nut.
you can get a ground loop isolator for about £15, but they just mask the problem - should really get it fixed if there is an electrical problem

Interesting. I have a 2008 Ford Mondeo from new. I'd hope that is electrically correct, but who knows.
I am awaiting delivery of a new car (Audi A3), so I will see if this has the same issue.
It's a real shame because the AUX out on the device increases the volume limit sent to the head unit and it makes a massive difference all round, this limit set by the poxy EU rules on the headphone out socket of the phone is really low (83% of max volume) and when you compare the two on the device its obvious the car kit is better.
BTW it makes the whining noise out of the headphone socket too, when plugged into cradle.

from what i've read, the noise when charging is usually from the alternator. do you notice the whine change when you speed up. if so, i'd get it checked out.
There is a method of basically powering the head unit direct from the battery, bypassing all the other connections and wires the juice has to go through to get to the head unit. probably what i will do if mine doesn't work after i've installed it properly.

I plugged mine into the radio today. From the headphone socket, no problem apart from a lack of volume (even on max gain, it is only just loud enough against the road noise). No background noise though.
Plugged into the connector on hte back of the dock is a completely different story. A ~10khz whine, which is present even with the 12V lead disconnected, and worse when it is connected. Sounds like breakthrough from a switch-mode power supply to me. Makes the audio-out on the dock not fit for purpose. Time to add my review on a fre sites selling them...
The other complaint I have is that it doesn't grip well enough to the windscreen.

I agree, although I get noise from the headphone socket when in the cradle and charging.
I have raised a returns to send my unit back for a refund. It's a waste of time having it if you cant listen to music on it! Imagine listening to the SatNav with all that silence and "whine" on the speakers, it would drive you bonkers.
It's a real shame as the overall quality is pretty good, but it is not fit for purpose in my opinion.
Will update this thread if I get any more news.

Just posting a review on Amazon... found this review too

This review is from: Samsung Vehicle Dock Kit for Galaxy S II (Electronics)
For the price, this does not do well enough. Yes it fits well, and holds the phone, with an integrated dock connector. However:
It is a push-fit corner grabbing design, and I find it almost impossible to release the phone with one hand.
The windscreen suction mount is feeble, so maybe 20% of the time rather than removing the phone, I end up with the whole thing coming un-stuck.
Dock mode on this phone is almost useless, so plan on replacing it if you think it is a good feature.
The audio-out functions, but there is a very poor electrical design - even if the charger is not plugged in, the signal picks up a constant high pitched whine (even with the car engine off)
Buy a cheaper one, and you'll feel less hard done by.

If you don't want to run a car Samsung's menu
If you don't want to run a car Samsung's menu install aps from the store :
Dock No-Op .
If you want to restore the default you have to uninstall the application.
Samsung Cars Menu and that sucks and this increased volume of system sounds, it's up scares. I think everybody can hear it in the around car
And what this menu is, and so one can make your own card to use in the car.
Personally, I mounted the Launcher 7 menu that conforms to the Windows Mobile 7 and has the icon in the system ankles. Cubes as they rotate with the vertical grip twist at the best level for navigation. This arrangement works well in the car, because after docking nothing changes and I can continue listening to your music on the equipment in the car, not a hundred times to click to activate the music listened to on headphones before
Sorry for bad english, but google translator

I was a bit apprehensive about buying this dock as I'd read a lot of reviews complaining about engine noise and sub-par audio quality when outputting sound through the line-out but since receiving it I've been really pleased with it. There is no engine noise or unwanted sounds so I guess this varies from car to car and depends on how your stereo is wired up. I've also run a few low frequency speaker test mp3s through the line-out and headphone-out it as I'd read reports of the line-out cutting off some of the low frequencies but to my ear I hear no different and I get a good response from my sub with both. My only gripe is that the call audio is not routed through the line out. Although I knew this was the case prior to buying, I just can't understand why Samsung would have left this feature out. I've read that this was the case with other Samsung phone's official docks previously and in most of the cases I've read about a solution has been found either through a OS/kernel tweak or an app which sorts the problem out. I'm just hopeful that a helpful dev is able to have a look at this and see if a solution can be found for the SGS2. Otherwise it's a great dock

I have to say I am disappointed with this dock. Coming from a Moto Atrix dock, this is poorly designed. Love my phone, hate the dock.
At first glance it seems extremely well made but after using for a while it is fustrating.
One, they use to many materials compared to the Atrix dock. This thing is huge.
Two, its hard to get out of the dock. The atrix dock had a nice flip up latch that secured the phone.
Three, you have to run two cables from the dock for changing and audio. The atrix dock had one cable coming from the dock with an audio out dongle near the end of the cable.
Last, the freaking background noise is terrible. Dont even try to listen to audio at a low volume.
I like the flip up charger adapter. Also it works with the official extended battery. But thats about it.

Using for Media Player in Car = Buzzing Sound

I use the phone as my media player in the car. When I plugged it in to the AUX on the car stereo AND it is on the charger there is a buzzing and whining sound. This was almost an instant return. However it seems to be that it is only in that condition if the phone is not outputting any sound. Once I engaged GPS, or MP3s the buzzing sound goes away (not quite but actually gone). I need to test more for long pauses in between navigation prompts, but it seems to be ok as long as some app is planning to make a sound to the headphone port. Maybe a power saving feature?
I never had this with my EVO, my Wife's Epic 4G, or any other phone I have owned.
-

I experienced the same phenomenon on an LG g2x. Only would buzz when NOT playing sound.
EDIT: not in a car, this was on an A/C adaptor at home.

the noise you are hearing is from the alternator of your car.( the whinning) go in your car hook up your phone and charger and give it some gas, you will hear what i mean. there is nothing wrong with your car or phone, its actually something that is rather common, so dont worry. you can buy a '' 3.5mm ground loop isolator to hook up and it should take that sound away.
hope this helps

using it as a usb drive, is better than the aux input
the phone isnt grounded very well, and will cause some noise issues
and the headphone output really isnt that strong in comparison to the evo series, imo

What receiver are you using? I tried the C3, but when it was fully charged fro some reason the sound goes to crap.

Here is a video of the noise. Note the car is NOT running. All the noise you hear comes from the stereo aux and phone. When I plug in my EVO, or the wife's Epic 4G there is NONE of this.
http://youtu.be/YoqdwVlpBAQ
It really freaks when panning and zooming.

I read this post this AM and decided to do my own testing. I used a Monster Cable 3, a generic Radio Shack cable, and something I found in a parking lot for the AUX, and 3 different car chargers and 2 different ones for the AC tests. I also tested with the music app, navigation, and no apps.
The results:
no apps - popping noises no matter what combination of cables or chargers I used
Music - popping noises when not playing music no matter what combination of cables or chargers I used
Navigation - popping noises when not navigation nowmatter what combination of cables or chargers I used
It seems that if you have something generating sound the popping sounds are gone (or at least mutted to the point where I didn't hear them). Otherwise, you get all sorts of odd noises as reported by other posters.
The car chargers were a BB charger, an iGo charger, and a Motorola charger and the test was repeated with both the engine running and just in AC mode (to keep the chargers active). The AC chargers were the out of box charger and my BB rapid charger.
I also repeated the tests with my wife's Evo and my old BlackBerry tour. Nether of those phones exhibited the same issue although both picked up some minor alternator whine when I was driving.

I can't tell what truck you got splashing through the puddle in your profile, but I am driving (having this issue) in a Nissan Frontier. I too tried several cables and chargers always with the same result. I even ran power from my Motor Cycle and Audio to the Truck AUX and still had noise.
So then I tested this in my wife's car (Chrysler Sebring) and the noise is not there, gone nada. WTH?
I took advice from someone else on this thread and hooked up a Bluetooth receiver to the aux and that works fine.
My conclusion is it must be something between my Nissan Aux and this phone when connected directly.

Car dock

Well, I got the Samsung dock, and as much as I like the E4GT, the dock is terrible. Here's my experience:
1. There's a ton of line noise when the phone is docked but nothing is playing, just like with the Epic. I'm using the OEM charger, but that's not the problem--using the same charger, the Photon's car dock is absolutely silent. Samsung must be using some cheap electronics in this thing, and it's simply horrible. (Sorry for venting, but seriously...)
2. The software isn't nearly as seamless as the Photon's either. First, on the Photon, when you dock an app starts that essentially takes over the home button. That means you can move back and forth between the app and the home screens easily. On the Samsung, it seems like once you leave the Vlingo app to, say start a radio streaming app, you can't get back to the dock mode. At least, not without unplugging/replugging the dock connector, but that's extra wear and tear. If I'm wrong about this, please let me know.
Then, the Photon app allows for 4 custom apps to be assigned. That provides a great deal of flexibility, and again it's easy to go from one app to another and then back to dock mode.
Overall, the Samsung car dock experience is nowhere near the Photon's. Motorola really did a great job with this, and Samsung makes it look like they gave actually using the phone in the car zero thought.
What's everyone else doing to make this experience more usable? I'm still choosing between the Photon and the E4GT, and the car dock definitely is a mark in the Photon's favor.

1) Use bluetooth audio streaming for zero noise. Are you connected by the dock's audio out jack, or the GS2's headphone jack? I noticed better sound with the latter, but using BT is easier and sounds so much better.
2) Ditch Vlingo for CarHome Ultra. Extremely customizable and lots of great features, including up to 18 app shortcuts and auto-switching day/night themes. I love it.

You could make a profile in tasker that recognizes when the phone is plugged into a dock. Or you can make one for when it is rotated in landscape and plugged in. Then, you can enable an app to run, or have a list of apps that you can choose from. This is what I do with my phone and I don't even have a dock. It's awesome how much you can do with tasker!

I'd love to do that, unfortunately my car doesn't have Bluetooth audio. And I'm going from the dock's audio out to my car's AUX in. That's an idea, using the headphone jack, but I hate adding wear and tear.

Thanks again for the tip, that app rocks. In fact, it's better than the Photon's car dock app.
Now all I need to do is find some way to clean up the line noise and I'll be a happy camper.

Go to radioshack. Ask them for a ferrite core. Should be a ring of "ferrite" or iron. Make sure it's big enough to put the plug on your audio cable through. Push it through and wrap it around a few times and see if that helps. Also, running a separate hot lead and ground from your car battery to the cigarette plug you use should help. But the ferrite core should be easier/cheaper

call audio routing
Has anyone else been able to get call audio to route to the output on the dock? media audio comes out the port so I can hear that on my cars speakers but when I make a call it comes out of the phone speaker....

So, I've tried a variety of power adapters, USB cables, and audio cables, and the line noise remains. I'm going to try the ferrite core around the audio cable, but I don't think that's the issue--if you unplug the unit from power, the line noise disappears. So, I think it's just bad circuitry in the dock.
One would think that Samsung would have received complaints about this with the Epic dock (at least) and would have fixed it. Motorola managed to make a dock with excellent sound quality and zero noise, so it's certainly possible.
Otherwise, the E4GT is decent in the car with that Carhome Ultra app. Although, that doesn't really help with my decision between the E4GT and Photon, because with the Photon I could have the same dock app but also outstanding audio quality.

I can only assume the noise you are hearing is due to a Ground Loop/Hum.
It has to do with the fact that your power source is grounded to a different point than the stereo/speakers. the hum you hear is the difference in voltage's between the 2 grounds being represented as noise in the line.
for instance. I recently installed a new head unit in my truck, the unit has an AUX in and a USB port. If i plug my E4GT aux cable into the stereo and plug the USB charger into the port on the stereo - NO Noise. However, if i plug the phone to charge in another outlet (say, the cig lighter) then there is Line Noise everytime. The same principle applies when plugging your phone audio jack into any electronics.
Hope this helps shed a little light on the noize.

I hear you, except that I have two different docks that display entirely different behavior. Actually, I have two docks from the same manufacturer (Samsung, for the Epic and the Epic Touch) that have significant line noise, and one (Motorola) that does not. Note that these are all plugged into exactly the same power adapter and outlet and using the same USB and audio cables.
So, you'd need to account for the fact that the Motorola signal is perfectly clean in precisely the same circumstances while the Samsung's signal isn't.

I believe every word of it.
From what I know about Ground Loop Hum there are many weak links in the chain, and certainly some products behave better than others. The problem is still most likely the Ground.
One possibility would be that the manufacturer of the Moto Dock has included an isolator in the power supply line (or even in the audio supply line), and the manufacturer for the Sammys didnt.
My experience in this subject is with my Laptop/DJ setup making noise when plugged into audio equipment. when the power supply was plugged into the lappy, 60hz hum. Unplug it and it goes away. More than likely the problem was inside the computer or the power supply was just poorly manufactured as other models may not have the Hum. In my case i purchased a small isolater solved the problem. It may be possible to find one for a 12v car electrical system.

I actually hooked up an old RadioShack groundloop isolator to the AUX cable, and it got rid of the hum.

Well, the salient point is that Samsung uses inferior components. It's possible to make a device that doesn't suffer from the problem, as Motorola has shown.

most times I've had line noise, be it from improper grounding or from cellular interference (namely from ground issues) the ferrite core fixed it. If it doesn't, the power isolation will. The reason the USB Ports on the head unit doesn't create line noiseis because it has isolation circuitry built in. The core is cheap. If that doesn't work, isolate power.

Okay, in the latest saga with the Samsung car dock, I noticed this morning that when I received a Bluetooth phone call, the TuneIn Radio audio I was playing didn't stop. Or, rather, it did stop once the stream buffer ran out, because I was on 3G and of course 3G data isn't available during calls.
Is this really how the Samsung dock works, that audio doesn't give way to Bluetooth calls? Or is that perhaps the CarHome Ultra app?
Still a bit frustrated with this aspect of the Epic Touch. The Photon's car dock works perfectly, including muting audio while on a Bluetooth call.
Grrr. I know, I know, if I like the Photon's car dock so much, why I don't I just stick with that phone... But seriously, Samsung, how hard is it to get this right?

I wonder if it might be the phone or the application. When listening to Sirius/XM radio without a dock, and I get a phone call, the radio keeps blasting away.

You don't stick with that phone because this one is superior in every other way. Its a minor issue. Why would you even have the aux input selected when there is no music playing? I have the noise too so I get it but ...yeah I just change the input when I don't need it.

Official Samsung 3-Pin Car Dock - No Call Volume after Removal Bug

Hello all,
For those who have the official 3-pin car dock, have you experienced this problem:
After removing the phone from the car dock, if you get an incoming call you are unable to hear the person calling you. You have to hang up and call them back in order to hear them properly.
I have experienced this on ICS and now Jellybean, it is extremely irritating. I had someone call for a job interview and I could not hear them, but they could hear me.
If anyone has a fix/workaround, that would be great.
UPDATE: I suspect the issue is with having it connected to the car via Bluetooth with music playing via auxiliary via the pogo pins , after that you are unable to hear the first call through the handset after leaving the car.

Have you checked your in call volume? Since the phone fits so tightly in the dock, sometimes when I remove the phone it presses the volume rocker down and lowers all of my volumes. You might want to check to see if that's happening to you.

Thanks, I'll try check that today. I would feel ridiculous if that were the problem, but I'm fairly certain its not since hanging up and calling right back fixes it.
It's interesting that you don't have this problem, are you also connected to the car via Bluetooth? Also what ROM are you running.

Do you mean that the Official Car Dock uses Bluetooth to transfer audio? I remember that there was a teardown of the desk dock in this sub-forum (I'm having trouble finding it in, for some odd reason...) that came to the conclusion that there was no Bluetooth and the audio was transfered using the pogo pins, like it is on (as far as I know) all the other pogo pin-equipped devices. (HTC Nexus One, MyTouch 4G, Rhyme, One X, etc.). For some reason the Android blogs and these forums spread the idea that Bluetooth is used, but it appears otherwise.
In other words, would you please clarify how you are connecting an external audio device to the phone.

Hi,
Here is the set up in my car:
Phone dock is connected to the audio auxiliary port on the car stereo for music. (The pogo pins on the phone send audio from the phone to the aux port on the base of the dock). The Phone is also simultaneously connected to the car hands-free system via Bluetooth. In my car, music goes the the auxiliary but calls come in over the bluetooth. (My car does not have the package to support Bluetooth audio streaming, only voice.)
I hope that makes it clear?

static noise when plugged in car

when i plug my phone into my car to play music its fine. when i use my car charger and play music at the same time tis fine but the second the music stop i hear a static noise from my speakers (which is attached to my galaxy)
this static noise is an imitation of whatever my car is doing at that moment (if im reving the engine the static will resemble the revs, same with turn signals)
anyone else experiencing this problem?

It's feedback from the car electrical system. Usually a bad alternator ground or corroded battery cables, or even the cables going to the starter.

i get that same thing =/

Damn, I was hoping this wasn't a problem on the gs3. It is probably the only true thing I don't like abut my skyrocket.

I'm assuming it isn't a stock deck? Check your ground and of possible try a new location.
All in all though, Androids micro USB is a horrible horrible connection. Every Android phone I have ever owned makes some sort of hissing sound while charging and listening to audio through the headphone jack. Even the Google Nexus does. But the iphone doesn't. Go figure.

I only get it using the cigarette lighter outlet.

On my i747m, I could not use the USB port to listen to music while I was charging via cigarette lighter. There is a definite design flaw. I bought an Ibolt dock and am not able to use it the way it is intended. Even when I wired it myself from scratch (I'm a sound tech) it failed.
Not only does it make white noise and static between songs, but there is some kind of GATE that kicks in 1 or 2 secs after any music pause....it cuts the noise in half but it still remains...and the act of cutting, is an irritant in itself. Further more, even when your playing music, the NOISE is fighting for sonic real estate. I can hear it. I am trained.
So for me, I am running the audio out of the headphone jack. It's 98% better but still not 100%. I don't get the classic REV issue...which has to do with grounding and/or cable shielding. But, if I was you, I would go to The Source store and pick up a Ground Isolator. They have one specific for car issues like yours.

Its a ground loop.

Is there a way to fix it?

It MIGHT... be a ground loop.
It might NOT.
Read my post #7.
If your using USB audio, there is an internal design flaw NOISE issue independent from any GROUND issues. (at least with my i747m) I can reproduce the machine like noise in the car, on a desk dock, on a separate stereo system. The Ground Loop isolator did not help my issue but it's worth trying if you get the hum/car interference noise from usb and/or headphones.
