This is EXACTLY what I've been waiting for. One less cable to attach to my evo

$80 is WAY too much for this. You can accomplish the same thing with a $20 BT3030 adapter, or any headphone adapter.
Here's a tip:
Grab one of these and one of these, and you'll never know the difference.

i just bought one on these and i'm liking it. Maybe it can be done cheaper but I know this works well.

It will let you stream to anything with an audio input.
EDIT: I'll have a full blown write up on this method in a few weeks hopefully. I'm waiting on a bunch of parts to come in and I'm hooking mine and my father's car up.

That doesn't look like it charges and outputs at the same time. The scosche appears to do this.

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.

[Q] Desktop Dock Line Out Electrical Noise/Static

After the release of Froyo I picked up the desktop dock. However, I found that when both line out audio and the micro usb charger are connect to the back of the dock, electrical noise/static comes out from the speakers (connected to line out).
I have replicated this with two different micro usb chargers. The wall charger that came with the dock and a car usb charger. The audio is perfect when only the line out is connect to the dock. But, as soon as a charger cable is connected static/noise immediately starts up.
Has anyone here both charged and used line out audio without any issues? Suggesting that I may have a defective unit, terrible power, unshielded audio cable, etc.
Thanks for any insight you might have on this issue.

Have you tried connect to a different setup of speakers or use a different audio cable? It sounds like you are having a problem with poor shielding on the audio cable connected to the back of the desktop dock.

I have the same problem, and I'm using the ear buds at work. I'm highly disapointed with the quality of audio coming from this device. I waited all this time and I get static!

same static with my dock

try samsung support.
their products, their problem...
its obviously a hardware design flaw, where the internal wiring/ components are picking up interferance, from itself or the phone.
WARNING SIGHTLY EDUCATIONAL: i dont have a dock but i cant set my phone within 1.5 feet of my alarm otherwize the alarm will "chirp" every few minutes. This is due to the alarm having a transistor radio and capasitors inside, the radio picks up the waves from the phone, and that energy builds up in the capasitors until it reaches max capasity then discharges to the speaker, chirpping.
chances are that they built the guts of the dock too small and compact, probably running the 3.7V power wires right along the auido wires which use less than a Volt, millivolts actually, and all wires with flowing electricity create magnetic feilds, the power wire would have a much stronger feild than the audio wire and could interfere with it, because inversly, magnetic feilds can create electricity in other wires (known as induction).
or it could be a culmination of the two factors.
back to topic, If it is the phone causing interference with the dock, it should have been built to be sheilded, if its the internal components of the dock it should have been designed different, EITHER way it would be samsungs fault or cheap overseas labour. I would gladly pay an extra (5-10%) on an item if it were made in North America (Can/US). Not mexico they take enough of our manufacturing jobs down there and might as well be overseas labour for quality and price.
if you dont care about the warranty pop it open and take some pictures for us, might be able to see/ possibly fix the problem.

At the time I tried with two different auxilery input cables, one well shielded for car audio and the other for a logitech speaker set; they both produced static. However, after restarting the phone it has yet to produce static. This phone and it's accessories are temperamental.

Ground loop
You have a ground loop, You need one of these.
http://www.crutchfield.com/p_127SNI...e-Filter.html?tp=2653&tab=review&rvm=ShowAllt

that is actually EXACTLY whats needed to filter out the interferance! nice i never saw a headphone one before...

Can anyone confirm that this device (noise filter) in the link solves the problem?
Anyone know of any other solutions, other than returning the dock? Shame because it is a great idea and is nice when it is working properly.

I just imported one of these docks, and the static on it really sucks, totally disapointed.

I haven't experienced static on mine due to the fact that I haven't gotten the headphone jack to even work in any capacity (media or calls). Has anyone had this problem at all?

I just picked up one and had the same issue. First few hours it worked great then all the sudden the volume went low and static started. 2 different power cords and 3 sets of headphones/audio cables later and still there.

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.

Best 3.5mm Bluetooth adapter for my car

I got the scosche by adapter from walmart for $36. It plugs into the 3.5mm jack and works well for audio streaming. Calls not so much.

All bluetooth adapters suck. I've tried 10+ different A2DP capable adapters over the course of 2 years and all simply ruin the high frequencies. Nothing beats hardwired Aux cable if you actually care about sound quality...

Google "tunelink"
A little pricey, but worth it for the audio quality. Plus, it is only for streaming audio.... No speakerphone function...

Sorry, but this is just a gimmick for those without knowledge in my opinion. Other than the bluetooth function, which there are a million of those out there, a person could just plug a male to male 3.5mm stereo plug into the phone to the AUX port in the car if its available.

I actually own it... I get WAY better quality over the bluetooth connection than I do with a direct line in. The headphone jack on your phone is designed for just that... headphones. Lining in directly reflects this. Wish there was a way for you to give it a try. I am kind of a sound snob, and I love mine. Plus, all you have to do is get in the car and once the bluetooth pairing happens, the app will open your music app and start playing.
Not trying to push this thing on ya. Just wanted you to know, I own one, and I am not "without knowledge"

Motorola Rokr T505 is small, does well with calls and music playing through blank FM stations to your car stereo. Best $40 investments plus NO CHORDS!

I had this one and used it with my EVO. Worked pretty well.
http://www.amazon.com/Miccus-BluBridge-Mini-Jack-Bluetooth-Bluetooth-Enabled/dp/B0038MA11U

I tried an AUX cable on three different phones. There was always a high pitched whine through my speakers. I started using a Samsung HM3500 plugged into the same AUX jack and got better quality music with no whine. Plus, no extra cable running through my car to the dash mount.

Did you guys all just have a car stereo that had bluetooth built in? I have an '05 Bonneville GXP but the stereo has neither a aux port or bluetooth capability...Major sad face...I really don't want to replace the stereo either because it's nice and fits the look of the car - would look stupid with anything other than a big touchscreen replacement and that's just too expensive.
Any suggestions?

You could get an FM modulator that would allow you to add a line in via your radio antenna, but they don't have great sound quality.

Yes, just swap out the headunit for one with bluetooth build-in. Just make sure it supports A2DP (music streaming over bluetooth). I got mine from Amazon for $140, Sony MEX-BT3900U, and it been simply great. A2DP for bluetooth streaming, Aux port for wired 3.5mm audio, and it has USB port for charging the phone.

High Pitched whine is a POWER ISSUE

Not all the time. My car had that problem and there were many other factors at fault.
Here are few things to look out for:
If your car has an amplifier in the rear, make sure that the headunit-to-amplifier audio cables are at least few feet away from power wires (aka, run them on the opposite side of the car than the power cables).
Make sure that the headunit is properly grounded. If that still doesn't help, run both headunit's + and - power wires directly to the car battery.
If problem still persists, repeat #2 but for the amp (if you have it).
If all above failed, it's time to invest in a better headunit. Your old one sucks and can't suppress the noise generated by the chassy/alternator.
I had crappy stock headunit and weaka$$ stock amp that would always make the static and constant whine problems. Ended up completely redoing the car audio system. Now, even with the headunit not grounded audio quality is PERFECT.
Here are the prices for my audio remodeling, all items bought brand new:
- Sony MEX-BT3900U. Headunit with CD, Aux, Handsfree Phone, Bluetooth A2DP audio, USB ($140)
- Hifonics ZXi80.4. Amplifier with 4 channels, 80W RMS per channel ($134)
- Alpine SPS-600 speakers. 6.5" 2-way speakers, 80W RMS ($50 ea)
- Stinger Pro 3 Series Snake. 6-channel, 20 feet RCA snake that goes from headunit to the amp in the rear ($35)
- 2x22' 8AWG battery-to-amp power wire
- 2x18' 12AWG amp-to-headunit power wire
- 4x18' 16AWG amp-to-front speaker wires
- 4x2' 16AWG amp-to-rear speaker wires
- 30A fuse in the engine bay
I ran the power cables on the left side of the car and ran the RCA snake on the right. everything was exactly $525 and I did all work myself (it's quite easy if you ask). now the sound quality in my used-to-be-audio-hell car is dam near perfect now and has absolutely no noise/static at all. you can jack the volume up crazy high without any distortions for like 80Hz+. 80Hz and below can be a problem when maxing out the volume as the speakers are only 6.5" and weren't meant to deliver bass. don't get me wrong, they do make nice bass but just don't handle it too well when playing it very loud.
after years of running this setup I'd say this was one of the best investments i've ever made. my car is built for drifting so it is setup very stiff and shakes/jumps like crazy when dailying (300mi/week) and when i do take it out for a spin the amount of stress it sees it crazy. after all this time you'd think at least some wires would come loose but nope, everything is still running perfect.
so yeah, if you actually care about sound quality in your car and would like it to last, just redo it from scratch. it's fun and is totally worth it

Not trying to pick a fight but lets be clear here
If your car has an amplifier in the rear, make sure that the headunit-to-amplifier audio cables are at least few feet away from power wires (aka, run them on the opposite side of the car than the power cables).
Which is a power issue
Make sure that the headunit is properly grounded.
Which is a power issue
If that still doesn't help, run both headunit's + and - power wires directly to the car battery.
Which is a power issue
If problem still persists, repeat #2 but for the amp (if you have it).
If all above failed, it's time to invest in a better headunit.
Which is a power issue
Your old one sucks and can't suppress the noise generated by the chassy/alternator.
Which is a power issue
See what I mean?
Cars make a lot of "NOISE" this noise is a power issue. it comes from your alternator and your coil and your spark plugs IE "POWER ISSUES"
if you have bad grounds or are lacking noise suppression (cheap equipment old equipment etc.. etc..) or an older car making a TON of extra noise etc.. etc..
Power inverters (especially cheap ones) are notorious for "dirty power" that lets in noise.
when I power my phone off the USB on the cheap inverter's USB port I get big time whine noises painful even.
use the USB port in the radio and I get no noise (but then it tries to "READ" the phone instead of just charging it and won't let me use aux hehe
Sometimes you can get a coil thing to add to power to reduce this noise but usually its just cheap equipment ($7 power inverter
plug a 110v to usb adapter into same inverter and no noise. The 110v adapter isolates and prevents the noise leakage.

haha time to clear up a misunderstanding here. my reply was referring to the "unplug your phone and it should go away" statement and thus assuming that you, by saying "its a power issue", were referring only to the inverter that was powering the phone at times getting a better quality inverter (aka, one that has capacitor or capacitor-pack to smooth out the voltage spikes and noise) is sufficient and at times it is not. I've experienced both. it's also worth mentioning that after redoing my sound system even the crappiest of crap inverters works just fine

Yes, just swap out the headunit for one with bluetooth build-in. Just make sure it supports A2DP (music streaming over bluetooth). I got mine from Amazon for $140, Sony MEX-BT3900U, and it been simply great. A2DP for bluetooth streaming, Aux port for wired 3.5mm audio, and it has USB port for charging the phone.

Yeah, I've looked into those kind of replacements...plenty out there for reasonable prices but they would completely mar the aesthetic value of the nice interior of my Bonny. That's why I was saying that only the touchscreens that would fill the whole double (might be 1.5) din stereo spot in my car would do.
Thanks, both of you guys, for your responses...guess I'm stuck waiting till I get a much newer car

I'm not saying that you're wrong about it being a power issue, but the BT headset I mentioned came with an adapter for an AUX jack and that solved my problem. So, either solution works.

the issue is the radio is connected to the same "power source" that your "phone" is now connected to.
so if any component in that chain does not control the power noise (that is what the noise is coming from your power system)
you INJECT that noise into your audio stream the moment you "link" the devices together (power not audio)
this is why if you use a seperate battery pack to charge the phone you will not get this noise. your battery pack is "isolated" from the car's power system literally physically.
I am only talking about the typical whine pop crackle high pitched noise you get the moment you plug in your charger. IE clear no noise plug in chargers Head burster sounds start coming out of your speakers
that noise is a "power issue" you can't eliminate the power issues (except by eliminating your alternator??) but you can filter it. some devices (chargers) do this better than others
the BT unit works because you "broke" the chain. (no audio cable going from the PHONE to the RADIO)

Again, I'm not denying what you're saying. You're absolutely correct. However, OP was asking for the best BT unit to plug into the jack, not how to solve the issues with cables and power sources. I was simply providing my opinion and experience along the lines of what he was asking for.

Samsung SGH-T989 Vehicle Mount

Anyone bought and have any reviews for this guy ?
Samsung ECS-K1F4BEGSTA T-Mobile SGH-T989 Vehicle Mount - Car Kit - Retail Packaging - Black
Listed for $33ish bucks on Amazon.

Looks like a good buy just wana know if anyone had bought this and liked it?

Looks like the one I bought from Best Buy. I like it, the only thing that I would warn about is that the phone can be a little difficult to take out. It doesn't want to just snap out like it should.

I have one. It holds the phone very well, but only without a case; absolutely no worries about the phone coming loose, and the phone doesn't bounce or vibrate, so the image is always quite readable. The only possible downside is that you might find the arm a bit short if you're driving a vehicle where the windshield is far forward, but then there's the adhesive disc, although I wouldn't want to go sticking some disk permanently to the dash of *my* car.
Leaving the charger and audio cables connected to the dock is very handy.
The phone recognizes that it's in a dock right away. There are a number of car dock launchers available (I like CarHome Ultra) as well as a car-specific voice mode.
The auto-plug charger that comes with the dock seems OK, but if you're using Navigator plus Pandora, your run-down battery won't get charged. I have yet to experiment with other high-amperage car chargers; seems like all the ones I have don't have USB conductors 2 and 3 shorted together, so they're pretty useless for this until I crack 'em open and solder.
I keep mine in a Toyota MR2 MK2 (little car) mounted at the bottom left of the windshield, and it's basically perfect there.
Oh -

Have it on my crv I can't live without it. Its easy to put in. Audio and charges are usable with one push. If you go caseless and are going to keep the phone for a while the price Is definetly worth it. Third party ones make you manually plug in charger and headphone Jack this makes it way more convienent.

It's pretty unfortunate that it doesn't work with any case though...too bad they didn't make a case combo that would fit that mount specifically.

for the price you can get other mounts that are so much better, look at Micro Center

For what it's worth, I have the Samsung OEM car dock as well and I absolutely love it. One thing I've found, though, is that the phone will occasionally go nuts thinking that I've pushed the button for voice recognition. It'll endless loop repeating "What would you like to do?" until I close out of the car launcher.
Not sure if this happens on the stock OS, I have Synergy+Bombardier loaded on it (rooted.)

I bought it. It's amazing, the dock mode syncs directly with my car stereo Bluetooth.
the only down side is you can not have a case on with it..

does it fit the phone with the Tmo D3O case on?

I'm definitely in the friction mount camp for car mounts. This one works great for me:

Bonus: works for your future phones and works with cases

Are you guys able to get call audio through the car speakers with your docks?
If so, please post how. I cannot seem to get call audio to route through the car speakers. Media plays fine, but no call audio. Almost a deal breaker for me. Thats what I bought it for. ;-)
Any help would be greatly appreciated.

Slap it on you dash and put the phone on top.

Try "car mode" in the market...

How to disable car mode for T-Mobile Samsung Galaxy S2 / SII T989 Hercules car dock
This is mostly useful if you use Bluetooth audio for your car stereo. This method renders your car dock's USB audio-out jack useless, and you would have to use the phone's headphone jack for an audio cable (untested, since I use Bluetooth audio). The only thing I want a dock to do is hold my phone and charge it. I automate the rest myself. Proceed at your own risk...
Car Mode Ultra is great for overriding your stock car mode, but I wanted to disable it entirely. I didn't like adding another layer of car modes and letting them wrestle for control.
Anyway, since I couldn't find a way to 100% disable the stock car mode software, I did it in the hardware (in the car dock itself).
On the back of the sliding part of the dock, take off the two small stickers and remove the screws under them. Carefully pry the slide apart at the seam to reveal the circuit board inside. Remove the tiny resistor between pads D- and ID. No more car mode!
Apparently, no more charging, either. Or at least not enough current to keep up. Maybe the car mode resistor tells the phone to charge at a higher rate, I'm not sure. Either way, the next step gets the charging to work again, but first, there's a warning:
If you don't want to burn your car down, make sure you have at least a 1 amp (1000ma) rated charger for this next part, otherwise, don't do it. This step increases you charge rate from 500ma to about 800ma (some people with custom ROMs go even higher). If you do this, and your charger isn't powerful enough, it could fry your charger. I have no idea what your charger will do if it fries. Maybe nothing, maybe light your car on fire. If you're not sure about it, don't do it.
On the side of the printed circuit board opposite the audio jack, there are two pads labeled A/R and AL/D. Shorting them to each other will put your phone into "AC charge mode", which means higher charge rate, no USB data, and no USB audio out. Now reassemble the dock.
With Car Mode Ultra and NFC task launcher installed, you can do all kinds of cool stuff. I set Car Mode Ultra to activate upon connecting to the stereo's Bluetooth. This starts the program without activating stock car mode. I stuck an NFC tag on the back of my dock for even more automation. Bluetooth turns on Car Mode Ultra, which unlocks the screen, which enables NFC, which reads the tag, which toggles more settings, starts Pandora, etc. Pretty cool. Full automation.
