[Q] Two Bluetooth in Car (One Apt-X) - Galaxy S 4 Q&A, Help & Troubleshooting

Hello All,
Galaxy S4 user x1 month and I absolutely love it!
I'm installing an aftermarket stereo head unit in my car, with bluetooth (Kenwood KDC-X896). I chose this head unit for the reviews and sirius-xm and a few other options available on it. http://www.kenwoodusa.com/Car_Entertainment/2012_Car_Entertainment/KDC-X896
Along with the install of the head unit, I am installing a Rocketfish Bluetooth Receiver with apt-X capability. The reason I'm installing the Rocketfish Bluetooth is to make use of the apt-X on the Samsung Galaxy S4. http://www.bestbuy.com/site/Rocketf...11138&ref=39&loc=01&CJPID=6149808#tab=reviews
The plan is to pair my phone with the Rocketfish play my music collection off my Samsung Galaxy S4 through the bluetooth Rocketfish (using apt-X) which is power-sourced to the car battery (switched) and plugged into the Kenwood head unit's AUX plug. This should provide brilliant sound from my phone through the car speakers.
QUESTIONS
1. Since the Kenwood head unit has bluetooth functionality as well, do you foresee any interference or issues with music playing through my phone?
2. Is it possible to pair the phone to the Kenwood head unit (to use phone via car speakers) IN ADDITION TO the Rocketfish (for music)?
3. If number 2 doesn't work, is it possible to go through the Rocketfish for audio and then switch to bluetooth on the Kenwood head unit for incoming calls?
Thanks for any help you can offer!

I guess it depends on the profiles offered by the Kenwood. My setup is to connect to the BMW inbuilt Bluetooth hands free, connect to an aptX Samsung receiver with a headphones out port plugged into the aux port of the car audio. When I get a call, it switches to the hands free automatically

Check out an app called sound about. You can choose what device different audio uses. For example you have media to be played through head unit and phone calls through you're other bluetooth device

Hi, thanks so much for a fast response! It sounds like what you're doing with your BMW is similar to what I'm wondering if my new setup can do.
A few questions:
1. The headphones out port you refer to - is this from the aptX Samsung receiver to the aux on your car audio head unit? (That's what I'm hoping to do with my Rockefish device). (Or are you referring to your headphones out port from your phone to the aux on your car audio?)
2. What kind of aptX Samsung receiver do you have in your car? (Can you post a link?) Is it similar to the Rocketfish?
3. Are you using specific apps on you phone to help in this situation, or is it as easy as it sounds?
Thanks again!

1. The former. Headphones out port from the apt x receiver to the head unit. The phone has nothing physically attached
2. HS3000. Google brings up loads of results for it.
3. No specific apps. Just regular bluetooth, with Play Music running .

Does anyone have a pioneer deh 7900bt?

Hey guys,
Does anyone have experience with this head unit?
I am getting this head unit in the mail and i wanted to know if it works as advertised with the mogul. I want to use it as a BT speakerphone and stream sirius.
Are there any tricks or tips for use with this head unit?
I am REALLY excited about it but I want to be prepared for it in case there are things I need to know.
Thanks guys!
Pioneer Premier DEH-980BT
I have the DEH-980BT (first model with bluetooth). Make sure you pair the pioneer head unit with your phone and after pairing register the phone in the pioneer unit (read the pioneer instructions) if you still have problems change the following registries in your phone
HKLM\Software\Microsoft\Bluetooth\SYS\COD
Change to 5898764
HKLM\Software\Microsoft\Bluetooth\AudioGateway\BTAGPBModule
Change OEM to \Windows\BthAGPhonebook.dll
HKLM\Software\Microsoft\Bluetooth\AudioGateway\BTAGExtModule
Change OEMAGW.DLL to \Windows\vcbthag.dll
You might still have problems setting both hands free and wireless stereo at the same time. I only have only hands free set on my phone and its works great.
I have the DEH-7900BT and it works flawlessly. I have to initiate the pair from the phone in order to get things setup, but once I have paired them the phone auto connects every time I get in the car and both the handsfree and stereo audio work as advertised. AVRCP even works correctly.
speaking of pioneer HU
has anyone tried the OEL screensaver studio appz ?
is there a site of people's creation available on the net ?
i can't find anything about it.
BTW, i have the 980BT unit and its top notch !
wait, so this radio has bluetooth streaming music right??, because i bought the Pioneer DEH 6250 BT and it doesn't have that function so i sold this 6250 to my friend and i was looking for this one 7900 because i thought it would bluetooth streaming music audio
why would one not use a cheap FM transmitter to do the audio to stereo? They charge the phone, use less power, and are like 4$ on amazon?
FM Transmitters SUCK!
1. Audio quality is crap compared to BT2
2. No A2DP support with a FM transmitter (on screen track info on your stereo, track fwd/back control, etc)
3. Noisy interference with other cars, towers etc.

Connect to car stereo

How do I connect the hero to the car stereo so I can listen to music through the speakers?
first you are going to need a bluetooth adapter or stereo that supports BT. Then pair them up and play. other option would be an aux connection.

Is there an adapter that uses cigarette lighter?
any mp3 player device that plugs into headphone port will work. Like the fm transmitter devices, that do plug in through the lighter. Just go to the mp3/ipod section at wal mart or best buy, they'll have it

DO you have an aftermarket stereo? If your stereo is stock, what is the year make and model of your car and i'll to see if you have the direct hookups. If you want great sounding music through your phones mp3 player, pandora, and ect.. this is the only way to do it (plugging split rca's in the back of the stereo and the other end into the headphone jack)
If your not so much into quality and just want to hear the music in your car a simple bluetooth device that someone reccommends on this thread would work - if your head unit supports bluetooth music streaming. Just because it has bluetooth on ur stereo it may only be limited to incoming and outgoing calls.
Then your only left with an FM Transmitter (worst sounding quality) not even the most expensive one will come close to the first two options you have above.
Post more details and I can help you. I'm very knowledgable with car electronics and installation.
Good luck

Thanks, It's for my wifes 2003 Honda CRV with stock stereo. I don't think there are any connections we can use. I believe we will have to use the cassette adapter (puke), but they are cheap...$5-$6 on ebay....
well, a cassette adapter is better than an FM transmitter.

Thats what I thought as well. Think that is what we will do.....
Yup you do have one connection that you can plug into. Its the cd changer port in the back... Theres an aftermarket harness that connects to a converter which comes with a cable that has 3.5mm tip on the end. This would be your best and actually not to difficult option. If you want to go with the super simple route then yeah cassette adaptor is what is used by many and its actually not that bad. Better than using an fm transmitter.

Car stereo that allows simultaneous bluetooth connections?

Does anyone know of a car stereo that allows (2) simultaneous bluetooth connections? Ive searched and obviously, they will allow multiple connections... but not at the same time.
Here is why I ask. I would like to use my Tab in its new Samsung car mount for media playing. But since I also still need to have a phone, I would like THAT to connect also.
Im asking for too much arent I? Anyone try a 1/8th inch audio plug to RCA cable? I guess I could plug the TAB in via the AUX port on my car stereo when its in the dock.
Anyone had any success? Any ideas? Am I crazy?

My Sony DSXS300BTX connects to both my Captivate for phone and my GTab for music. It will switch source when a call comes in, and resume playing when the call is done (can't recall if it pauses or just mutes the music though).
My girl's Kenwood DNX5160 can also do dual BT connections for phone+music.
Thanks guys, I will check these out... I was dreading having to use the wired aux output!

[Q] Using galaxy 7.7 as headunit + hands free calling

So here's what I wanna do -
I want to use the galaxy 7.7 (preferred this model just because its the only galaxy with call function) instead of the stock head unit in my car. I was thinking of going completely wireless and streaming the audio to my car amp via a bluetooth receiver. But what would happen when I receive a call? the sound will be streamed to my amp, but what happens with the audio in / microphone ?
Would it be enough to speak straight to the tab's microphone? will the microphone be enabled at all?
The other option, which i prefer less is to run wires to my amp rather than using a bluetooth receiver, and via bluetooth connect to a hands free car kit (but this means I would have to plug in the audio each time as I wont leave the tab in my car ever)...
Any suggestions on how to get this done?
PS is there any hack available to use the call function on the galaxy tab 10.1?
Thanks!!
Unless you have some sort of amplifier that received power and signal wirelessly, you're going to need some kind of line output converter to get audio out of the gtab 7.7 and into your amp. What you're talking about doing, if I'm understanding you correctly simply can not be done.
Work well with audio cable ^^ tested calling or streaming from 7.7

well, using an audio cable to extract the audio would be along the lines of a line output converter, like I said before
what the OP is talking about is having something that's completely wireless, that will act as a source unit and interface with his amplifier ... wirelessly. Simply just won't work that way.
I have considered doing this (just ordered a GT 6800) but see now that there are android head units starting to come out. Still, you can always use bluetooth to connect the GT to your sound system. It will have good stereo sound and also have the mic input.
Here's my set up: Tab 7.0 plus wifi only but I use a hotspot on the road. I'm using cables to connect audio but thought about bluetooth, but I think you get better sound with cables maybe not! why buy a head unit $800.00 that doesn't give you a 1/4 of the functionality you get with the Tab.
Sorry forgot to post picture
i use bluetooth for my audio because i like the way i can use my steering wheel controls to do next/previous track on the tablet.
The audio is fine for me, but current bluetooth still not as good audio-wise as a real cable. If you use a cable and power the tablet at the same time you may get a hum - if so, put a PAC SN1 to reduce the ground-loop interference.
Bandzdaddy - It looks like Torque app, am i right? I use that as well because my turbo car didn't come with a boost gauge and Torque let's me have a virtual one!

Android Head Unit + Pioneer DEH-PRS80

Hello everybody , I'm owner of Ownice C200 Chinese head unit and i hate about audio quality and Bluetooth. I was using Behringer UCA 202 Usb dac but few months ago it stopped to work. Dac working with other devices but with head unit it is not working. When i use USB audio player, I can hear sound via headphone but from stock car speaker , no sound. For this i bought line converter to connect directly RCA from USB dac, but then i learned it need amplifier to power speakers. ( if i am wrong , please correct me)
I search a lot of topics in XDA and i saw one message using two head unit in car but there is no more information. I want absolutely same things. I want to use Pioneer deh-prs80 ( i will hide it somewhere in car) and will continue to use Android head unit for navigation, watching movies, rear view camera purpose. Is it really possibly ? I don't want to install any amplifier to my car, i don't need loud music, i just need clear and crystal music. I have hertz esk 165.5l as speaker.
If it's possible how will be connection ? Car battery enough to make power for both head unit ? ( i will connect speaker wire to directly pioneer) , is it possible to connect android head unit to pioneer via aux or Bluetooth or what ? I wish when i use android head unit, sound will go to pioneer and this head unit amplifier to speaker quality sound.
I also wonder if it is possible can be sound quality difference playing directly from pioneer or through android head unit to pioneer ?
I hope this topic will help to people who suffer from audio quality expect other features in android head unit..
Nobody can help ?
Well I would connect it via Y Splitter and the Front RCA out on the HU would go to the AUX in the Pioneer deck and connect your bluetooth to the Pioneer HU instead of the Android. You would have to zero out the sound from the Android and adjust your EQ settings from the Pioneer to get the best quality needed.
