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.

[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!

[Q] Two Bluetooth in Car (One Apt-X)

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 .

Connecting via USB to processor/DAC - Eonon GA8150 Android 7

Hi Guys
I have been searching and researching for hours but can't get this to work the way that I want, although I don't see any reason why it shouldn't work.
I recently purchased one of my dream cars, and promptly changed the headunit to a more modern unit, to allow me to have spotify, google maps, etc etc. I purchased the Eonon GA8150A for this purpose, and it sounds OK.
I was always planning to upgrade the sound, namely using a Helix DSP and amplifier, upgrading the speakers, etc etc.
Since the helix has an optical input, I figured I could maximise quality by running a digital signal to the unit - to this end I purchased a Behringer UCA202, as its a class compliant USB DAC which has optical out.
I connected via USB, and went into developer settings, and changed the "Select USB Configuration" to Audio. I plugged in some headphones for testing, and....nothing.
After some research, I downloaded the Onkyo player, and this worked! I was getting audio via my USB dac, through the headphones. But spotify, bluetooth, radio, nothing else worked.
Was wondering if what I am trying to achieve is possible?
The only other alternative it to sell the uni, and purchase an AVIN Avant 3 unit - this comes with high quality 4V pre outs but its a lot more expensive and i really dont want to do this. I could use the RCA outs on the Eonon to feed the processor, but as mentioned, these leads to many stages of A/D D/A conversion that will markedly reduce quality.
Thanks
Saad

Ok updates - it now works - the inbuilt audio player via USB, spotify, both work, however the radio doesn't send audio via the DAC, and nor does it send audio to the dac from my phone via bluetooth.
Not sure why this works now, maybe I had to turn off the car a while so the unit could properly reset?
The head unit volume control however doesn't work to adjust the volume of the audio coming from the dac.
Any way to get radio and bluetooth working via the dac?
Cheers

Head unit with fully working bluetooth?

Does anyone have an recommendations on an double din android based head unit that has a fully working bluetooth module? Something that can pair with and control an Alpine PXE-0850S amplifier. Does such a head unit exist?
Thanks

I would also like to know if such a product exist.
With new headunits including plenty of memory, storage, fast a75 cores and 4g -but high noise floor and only 2 slow usb ports+crippled BT is such as letdown :-(

I noticed the Atoto units have two bluetooth modules and support bluetooth tethering. Any chance those will pair with generic devices?

Well, I answered my own question by buying an Atoto S8 and trying it out. The second bluetooth module seems to be a normal fully working module and does pair with the Alpine amp and allows the amp settings to be configured using the Alpine app. However, since the amp also supports bluetooth streaming, whenever the head unit connects to the amp over bluetooth it routes audio output from music apps (but not the radio) via the bluetooth connection (instead of spdif), bypassing the head unit volume controls. So whenever I want to change the amp configuration I have to pair it with the head unit, run the Alpine app, make the changes, and then unpair the amp. Grrrr.....
