ad2p streaming with carGeneral


  1. I test drove a few cars today, two Acura's, and a 2013 Honda Accord. On all of the cars, I paired them with my phone and played music through the cars audio...

    In all three cars, the signal was a mono signal, and not a stereo left/right signal. It sounded horrible....

    Can anyone verify that the Note 2 does in fact stream music via bluetooth in stereo. I suspect it was the cars, but hard to believe it.

    I used the Foo Fighters song, "Rope" as my test. The guitar starts on the left hand side.

    Thanks!!

    I am curious too because this would be a deal breaker

    I've been using an bluetooth 3.5mm adaptor I purchased from ebay and it's hard to say, simply because I made adjustments on PowerAMP, using the equalizer, so the sound is still pretty darn good...and still seems to transmit in stereo (possibly because it's still connected to the 3.5mm adaptor vs. going direct bluetooth to the headunit).

    That said, there was a brief moment where the USB connecter was not allowing the unit to charge and I had to use direct 3.5mm input. When I did that, I did notice the sound jumping up significantly from bluetooth. Again, not an issue for me because I can make the adjustments through PowerAMP's equalizer, but it might not be acceptable for many people.

    Were there no equalizer settings on the OEM headunits (on the cars you test drove) that would allow for Stereo bluetooth transmission via A2DP?

    It was the cars or bad pairings. The Note 2 uses AD2P. I use it with my Car (using Griffin's Blue Trip) and my Pioneer Receiver in my living room and it sounds great. No adjustments or equalization.

    "Rope" is a great test track to quickly check the stereo split and dynamics as well as just a bad ass track, period.

  5. I suspect it may be because I had a setting set in accessibility settings. The setting is supposed to make the signal mono when paired with a one earphone earpiece. I have a feeling this was the culprit today. I suspect the setting is applied globally to all bluetooth pairings once set. Ill have to go back and bug the poor salesman...

    I have a 2012 Acura TL with tech and own an iPhone 5 and stereo works fine on my car. Mi ordered a note 2 now and will be my phone to use with the car. It better work stereo or it goes back. It's not the cars.

    In some cases, it may be the cars.

    A lot of audio in cars are made for iphone/ipods. They don't care about android, so they don't build for them.

    As long as your car has some kind of bluetooth capability, you'll be fine.

    I have streamed a Note 2 to a 2013 Mercedes and Lexus in stereo. I verified this because I adjusted the panning / balance. In an older Lexus I use one of these and it works perfectly with Note 2 / iPhone 5:

    Auto on, auto connect, small, cheap, loud and quality audio. I can't say enough good about it.

    Sorry, can't post links.

    No problems with 2012 BMW X3. Syncs up fine with good sound and stereo.

    Keep in mind that if you choose to use Bluetooth to connect to your car stereo that you are likely giving up voice input to the phone. When I use Bluetooth in my car I am unable to use S Voice or Google Voice Input... both tools that come into play when you are driving. I'd make sure that direct line aux input is an option in any car. I switched to that primarily for this reason.

    On my Acura when I used Siri on the iphone 5, it stopped the music and did the beep in the speakers and used my mic on my car to listen. Worked great. I hope this isn't a downgrade on the phone with the way it works with my car.

    I stream bluetooth music to my Pioneer DEH-9400BH without any problems, except that it doesn't display any track info. Bluetooth calls work fine, as do voice commands when background noise isn't a problem.

    Actually, now that you mention it, you are correct. It will depend on the bluetooth set up of the car. It will use the vehicle's microphone to pick up your voice. In my case, I have a 2007 Toyota Camry Hybrid where it only has hands free calling. It will not work with the phone in this manner. Newer systems using both phone and media profiles will.

    It will "work" with my Griffin BlueTrip adapter, but because it is little more than a blutooth device built into a vehicle power plug with the mic located on it. .. it picks up your voice too poorly to work.
  14. Very true....I hate that using bluetooth breaks voice input. My research has shown this was fixed in the Google OS update...but no telling when Samsung and the carriers will push that out.

    I think the mono feed was coming because I had under accessibility mono audio for single earpieces. I bet this setting still applied hooking up to the car. I decided against buying a car anyways.

    It's not the car, it is something with the Samsung BT stack.

    While I have no issues with the output being stereo, neither the GS III, Note 1 or Note 2 will maintain a connection to the BT in my car or my wife's.

    Every time I turn the car on I have to go to the BT settings, find the car, click connect. If I turn the car off, I have to repeat the procedure. It is a major inconvenience and something I have not experienced with any other phone.

    Every other phone I tried it just remembers the vehicle and if I start the music player, it starts playing through the car speakers.

    None of my Samsungs have ever done that.

    You need to revisit the issue because it does sound like the problem is your car. I have absolutely none of these issues with either the Note II or GS III. I get in my car. .. The phone automatically connects to both the built in hand free bluetooth and the Bluetrip adapter. The only issue I have has to do with voice commands/input. It tries to use the mic on the adapter which is inside the dash compartment. The car mic only gets used on calls.

    What car are you driving?

    I have a 2011 BMW X3 and it automatically pairs everytime I start the car.

    Went and hooked it up to the car (2012 Acura TL) and everything works great. Bluetooth Stereo streaming from Pandora, or my MicroSD card. Phone calls also. It disconnected and reconnected fine too. Downloaded the address book like a champ. :)
