3.5 Audio Jack Issues - EVO 4G Q&A, Help & Troubleshooting

Searched but didn't see my issue dealing with the EVO, so here it goes.
Bought a 3.5 audio jack adapter for my EVO to work with my new vehicle. First time owning a vehicle with this type of adapter so I thought I'd give it a try, since I have Rhapsody and can listen to any song/album/artist I want at any time.
However, when I use it, there is a ton of "feedback" so to speak. A high pitched noise that gets higher the faster I go for example.
So, I tried to figure it out. I tried my wife's EVO, same thing. Well, I thought it was a cheap adapter or maybe the hardware in my Terrain was really not compatible.
Turns out, my brother sits in the back seat, pulls out his IPod to test it out, and it works perfectly! No background noises, no hissing, or anything. Just pure great sounding audio.
So, I guess my question would be to those who are hardware literate about the EVO.
Did they skimp majorly on their audio out/3.5 audio jack?
Both phones are running 2.3.3 GB, but it did the same thing on 2.2.
Any thoughts, answers, or suggestions?
Also, could it have something to do with using 3G or streaming the audio through the adapter since his IPod was basically just a straight feed?

My guess is the line noise is caused by poor shielding in either the cable or the device. If you're saying plugging the adapter into the iPod made the noise go away, then I'd blame the Evo for picking up EMI from the engine, or it's possible you have a ground loop.
Either way, not much you can do about it except find a way to ground your adapter (don't just go splicing wires, you could fry something) or find a new adapter. Was the adapter made for Apple products, generic, other? Sometimes the TRRS setup of the audio jack can be switched in different devices, so maybe it lines up correctly on the iPod but not your Evo and that could be the source.

It was generic. Bought it from a K-Mart. It may very well have been made for an IPod though.

With a DC electrical system (like in your car), that's a tell-tale sign of interference or a bad ground. Try a new cable, if that doesnt help, then your radio isn't properly grounded.

Audio fans- Suggest waiting for 3.5mm jack version

Seems like everyone but the first runners and (Tmo) are getting the version with a 3.5mm jack. I think Tmo will also get this version too once they bleed out stock. My guess is the next production runs of TP2's will have the jack for Tmo.
Makes sense from a production standpoint in regards to sub-assemblies. HTC's decision to finally bail on usb audio happened during TP2 production.

Eh, I'll just get my 1st gen TP2 replaced under warranty or something when the new 3.5mm one comes out for T-Mobile. Until then, I'll be perfectly happy with what I have.
I really don't get this whole 3.5 debacle. HTC has been making devices with their proprietery USB audio connection for years. All of a sudden some high profile blog sites start clammering for 3.5 and everyone feels they cant live without a 3.5mm headphone jack.
I'm not trying to rant; I rarely use my phone for audio since I have a Zune. Could someone please explain to me why this is such a big deal. They way I see it, if you are buying a WinMo phone purely to listen to music you are wasting your money.

Just because you listen to music on your Ipod or whatever mp3 player you have doesn't mean that we all should do the same. On a side note, I think everyone has the right to spend on things they want.

My biggest reason for wanting a separate headphone jack is so you can plug your headphones in at the same time as a power cable, so you can listen to your MP3s on power while keeping the battery fully charged.

I have to carry a cell phone. I need to carry a PDA. I want to carry a music player.
I don't want to carry more than one device and besides, wearing more than one headset at a time makes me look strange.
S
That's why A2DP is soo great. I love using it especially since cables always die out on me. My headphone jacks used to get caught on whatever and I'd be buying a new set of headphones for my discman back in the day at least once a month (one month I actually ended up buying three pairs). Which is why I don't care about the 3.5mm jack.
well .. first off bluetooths great but i get iffy reception sometimes when attached to my body lol and of course the sounds not great good but not great... also i personally did not buy this phone just for music because then ide get a feature phone .. but i love music and require it a standard in a 600$ phone. second you can use the adapter but.. it sticks out of your pocket and when you whip the thing out youve got this glorious phone with a hideous alien brick sticking straight out the side ... and last note... in my experience with any form of mini usb, it wears down and pretty qick dep. on usage .. if i constantly plug in and disconnect for charging and syncing thats bad enough but many many times a day when you using headphones and this usb port will be lose in a few months where you haver to wiggle it to make it work . this happened on my kaiser, mogul and a blackberry i had (on kaiser i had to eventually use a piece of folded tinfoil in the port just to get it to charge under a year old..) ... on topic- i really hope us t mobile users can eventually get a 3.5 mm like through warranty/insurance because i am PINING for it! lol

Wow! If everyone is planning on replacing their TP2 on warranty then it might make monetary sense for T-Mob to stick to only the USB versions. wow! wow! wow!
Sure, you get a built-in headphone jack, however, from what I read online, CDMA versions will not allow phonecall + data at the same time. Only once the 4G network comes out will this be possible on a CDMA phone. So all of these CDMA touch pro 2 future owners are giving up simultaneous DATA + voice for a headphone jack. Then again, those that are already on a CDMA network will notice no changes from before.

Then I'd be able to keep the phone charged... while and the bluetooth headset batteries would be going flat.
Andre
This is all a non-issue to me. From what I recall reading it is Tmo that specified they wanted their TP2 to be 3.5mm-less to HTC. So that is what HTC built for them. I wouldn't hold my breath for a TP2 from T-mo being 3.5mm inclusive at any point.
If I am in a location where I can charge my phone, I'll play the music through the speaker. It'll go through a headset if I'll be away from a power source (aka desk). And I have two options there, either the RC E100 remote (from my Kaiser days) which has a 3.5 jack or via A2DP with a Sony HBH-DS220 (3.5 jack), feeding a pair of Etymotic ER4P's with a 5" lead. Both have built in mics, keeps the phone holstered and out of sight.

Evo to Ipod Dock Adapter DIY

I would like to be able to connect my Evo to my car so that I can listen to Pandora using the car stereo. Unfortunately my car only has an Ipod dock connector.
Would it be possible to create an adapter that will allow you to connect an HTC Evo to an Ipod dock and output audio?
I have seen something similar being done with a T-Mobile G1.
webnetta.com/2008/12/27/hack-connects-t-mobile-g1-to-ipod-dock/
Is it just as simple as getting a Ipod dock extender cable like this one:
monoprice.com/products/product.asp?c_id=108&cp_id=10831&cs_id=1083101&p_id=6828
and cutting off the male and of this cable and soldering it to a male end of microusb cable?
Any help would be appreciated.
this is a huge area where android needs improvement.
There's no audio through the Evo USB port. I was searching for the same thing last night. I have a logitech ipod speaker: (can't post links)
I also have this ipod bluetooth adapter:
What I'm thinking about doing is to hardwire the bluetooth adapter to the inside of the speaker. Then get the 5v from the dock and make a cable or adapter to go to the Evo's mini usb port. It's not the best solution, but I do have all of the parts already. If I didn't, headphones would suffice.
find the schematic for the ipod dock and solder a headphone jack to the audio inputs on the connector and you're done. I have done the same thing and it worked just fine for my friend that I did it for.
the thing that sucks about that is you will need an extra cable to charge the phone.

Hence my bluetooth idea.
I did some digging around a couple weeks ago and came across this

It sucks you need the 3.5 adapter, but better than letting letting a perfectly good dock sit and collect dust.

I just ordered a couple of these last week. My car has an ipod adapter, and this should let me connect to that and connect the 3mm to my EVO.
It's coming from Hong Kong so may be a bit longer before it's delivered. I'll report back when I get it.

I had the same problem, I think the best solution is to go Bluetooth. This will future proof you for phone changes down the line as well. Long story short, here is the best solution I've found and it works great! Just connect it to your ipod cable and stream over Bluetooth. So far it has worked with everything ipod, iPhone and iPad that I own, especially my custom installed iPhone stereo connector.

Step 1: Buy some Sugru or ShapeLock
Step 2: Buy Cheapie $1 headphones
Step 3: Buy iPod female Dock connector and MicroUSB Male end
Step 4: Use Pinout.ru to connect the points appropriately (iPod dock connector pins are pretty small and you must work quickly or your will melt the plastic, do not forget the internal resistors if needed for your application)
Step 5: Wrap it up in Sugru or Shapelock (use hairdryer to smooth it out with your hands)
Step 6: Paint and Enjoy!
Creating custom cables and docks and such is really not that difficult, just need some decent soldering skill and patience.
You could also just buy this:

FIPO Bluetooth
I use this in my BMW for streaming over the bluetooth to the stereo. Works great and convient to just start the car and the Evo start playing music/podcast/etc.
FIPO Amazon Sprint search will turn up the 20 dollar adapter.

Some of us do have the necessary skills, but do not want a ugly wire staring us in the face. Also the components themselves tend to get expensive when ripping apart 3 different cords for parts... not to mention when someone tries this and melts something, then you have to go through the hassle of ordering more components. That is the main reason we come here, because someone may already be on the job.
Now..... if your offering to do it, and you have a pricetag and are willing to offer support in case it doesn't work or kills our phones or car stereos, then I am all ears. But definitely thanks for the link.
As far as BT goes, the one poster is kind of right, I think the phone industry is betting on bluetooth, although its been 15 years, and BT performance is still at best Mediocre.

True, But there are those of us with drive to do something unique and have something that fits our needs exactly. DealExtreme.com is a great place to buy the cables to be ripped up and dollar stores can be a real treasure trove. Craft/ART stores also have a lot of things which can be easily repurposed.

I used to be a person who did his kind of work in college, but it is time consuming and repetitive. Plus, this is likely a market of people who are not willing to spend great amounts of money on handmade products. Even if someone charged $30 each it would not be worth the average techies time, but a worthwhile effort for a high school or college student with the drive to learn and perfect.

You are correct in MOST scenarios!
It is more of an issue not with the BT technology itself rather the way it is popularly implemented. BT does have the ability to send out very high quality audio streams and many of which are nearly lossless in quality. The issues are with the device that streams and the device that receives. The chosen connection type between the two devices must be mutual. Problem is that most BT devices streaming A2DP use only SBC coding of varied bit rate and quality.
Now if you have a really well done setup that is very thought out you can have your EVO sending out a pure 320kbps MP3 or AAC or other compatible stream direct with no conversion being done in real time to a BT receiver which is MP3, etc. stream compatible and has an excellent, typically non-chip integrated, DAC with a nice buffered output. Problem is that many BT receiver chips are made to be as cheap as possible, have crappy dacs, and push out very little power (or simply have no buffer at all) to even crappier speakers. When you combine that with real time conversion of MP3 and other formats to SBC at an even lower bit rate, you have an even worse experience.
IMO, the headphone output on the EVO does not sound that good and if you have a car that does accept MP3 320k BT streams and you use an alternative media player like meridian that allows that kind of behavior, then it should be fine for even above average car audio.
Have a Great Listening Experience!

Well, that was a mouthfull. Thanks though, it helps a little. I did spend quite a while researching different Bluetooth headsets. But alas, as you have pointed out, although most of what is considered to be high end headsets, still only use bluetooth 2.0. The EVO also doesn't do a very good job at streaming bluetooth. Pandora and Music Player skip horribly. I was not aware that Meridian did a better job. I guess, that might have been another option.
As far as the bluetooth headsets go though, if your looking for A2DP, the selection is still limited, unless you want a dongle type headset, which IMO, you might as well use a wire. The Motorola, Rocketfish and Jabra headsets of top end just don't do as good a job as seating properly, unless you spend 50+ dollars on a custom ear piece.
There really are a lot of trade-offs in audio performance, but a good set high quality ear buds or headphones are hard to beat. Then comes the Car audio as well as home audio into play. I use mine as a MP3 player both on the go and in the car. My car has a Audio In jack, so I am happy with that.
I ordered a E5 Amplifier to go with mine, it should be here in a week or two. While my headset has finally broken in, I could do with about 10-20% more volume, but I am hoping for a little improved base since it will have the power to push my Vmoda Remix.

Yeah, The E5 is a decent beginner set. You may want to look at building a CMoy at some point, make sure to use slightly larger electrolytic caps and good film caps (resistors don't matter as much). If you make one with good parts and socketed chip, you can roll in to your flavor and it will take portable amps that are $100 or more to beat it. As far as kit amps go, its hard to beat a Mini3 for $100 to put together yourself.
I only say this as a person who actually owns a $450 Portable Amp and $575 Custom triple driver In-ear's. Don't even get me started about the stuff that is at home (I have way too much audio crap!)
BTW - you can make your own custom silicone ear pieces by using some Sugru or if you know an audiologist, you can get some of the Westone two part silicone that they normally use for getting impressions. As with everything, be careful and YMMV.
I wish i had the time to work on getting a USB host for the EVO so that we could use external USB DAC's (like the very small alien and grub).

$80 is WAY too much for this. You can accomplish the same thing with a $20 BT3030 adapter, or any headphone adapter.

I just used that as an example as how cheap you can go. Personally, I'm making a cable that does both.
If you want one that charges and plays at the same time out of the box, try this for 20 bucks:
http://cgi.ebay.com/New-Jabra-BT303...uetooth_Wireless_Products&hash=item4aa3833d38
It's the Jabra BT3030. One end is the audio output (which plugs into your audio input) and the mini USB port is on the other for charging.
Looks awesome but quality of sound is probably ****...
How is bluetooth sound quality now adays. I listen to flac, which is lossless audio, so if it isn't really good - great sound quality wise I will just keep using a 3.5mm cable.
I'm not an audio expert (nor is my ear sensitive enough to pick up subtle differences), but I definitely wouldn't call bluetooth audio ****. I can't tell the difference between the bluetooth connection and wired connection. I've heard accounts saying flac sounds beautiful through bluetooth, but then again audio is something that has always been subjective.
Thanks for your opinion, i appreciate you taking the time to respond
I got a motorocker or something like that yesterday at walmart. It was like 90 bucks regularly on clearance for 60, but i got an extra good deal on it.
When i get my evo back I'll post my opinion on it. I have audiophilistic ears lol. It also fm modulates, so i know frequency is going to limited on the upper end to 16kish. But much over 16k doesn't contain much musical content depending on what you are listening to anyways.
Not that great over FM, glad i didn't pay much for it. I am sure the device you listed would sound very good though as it goes through a regular aux port instead of fm modulation. There didn't appear to be any bluetooth related noise, just fm garbage.
I bought a new Sony desk (BT2800) with Bluetooth built-in, and the quality is near flawless. It seems like I actually have less distortion than when it was physically plugged in. There was a ground short or something when I had it plugged in to charge and to the aux input ( but you only could notice if u turn the volume up with nothing playing). I don't know if that's with all cars or just my older car.
scl23enn4m3, you don't know what you are talking about. I hope people don't follow your ****ty advice.
First of all, that BT thing you linked to on ebay does not charge and stream at the same time. It has been covered in the comments section on dealextreme.
Second, I have yet to find any bluetooth reciever that I can add to my stock stereo system that will auto-pair. Auto pairing is a huge deal. If you have to screw around with the bluetooth settings on your phone every time you turn your car on, you might as well plug in the damn aux cable.
I am excited to check this product out.
so mine came in i couldnt get out of my car lol
i think im going to buy one for my home surround sound so i can stream music from laying in bed from my phone (my best tunes are always on my phone even though i have a 2tb and home server running boxee setup on my tv)
But seriously this motormouth btaxs is amazign (for you cheapskates out there stick to your long wires or jerryrigged stuff and leave this toy for those who want it all done right without soldeign and running wires all over)
Yes it charges while in use (I have mine plugged in all the time now and i have it setup so once i put my evo in my dock it auto ons my bluetooth and connects automatically to it)
call quality is good i just tested in loud car on speakerphone and no reverb and works flawless with one button touch then speak the name u want to call
love the damn thing i cant wait to go to work i use my phone all day while driving around and havign to plug in two wires everytime i get in and out was askign too much
now only need one wire and thats if my battery is dead ill add pics in a bit

Too bad my '07 Porsche 911 doesn't have a Aux/MP3 input jack.
Woo-Hoo!
Ordered mine from Hawk Electronics on Wednesday night - showed up on the front doorstep today (it helps that their warehouse is here in DFW).
This thing is amazing. Sound quality for music over BT far surpasses what I was getting via 3.5mm jack, and there's no 25% sound reduction just because you docked. In combination with my Sprint car dock, this is just exactly what I've been waiting for. Cool thing about car dock mode: it turns on BT, GPS, and 4G when you dock. It paired without issue, and it fires up the second I dock it in the car.
I used the extension thingy for the microphone, because my AUX port is over on the passenger side in my Element.
Road trip tomorrow.
Here'sa pic comes with charging cable too with car adapter

This device looks nice but too bad my aux input is in the glove compartment...

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.
Something like this should work fine: http://www.amazon.com/GROUND-LOOP-I...QTRI/ref=sr_1_2?ie=UTF8&qid=1322958491&sr=8-2

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.
