[Q] Strange BlueTooth Functionality

This functionality has to do solely with my car, the Mazda3(2912). Now, I've tried a few devices and get different results. They all connect to the car, and I can hear audio from music, and phone calls. I'm not too crazy about the quality, that's not my prior concern.
The issue I am having, is the readout on my car's display unit. If it works, I can search through my device's music and select specific songs or playlist, and it will also read out what is playing. If it doesn't work, it will just show "BT Audio Streaming", and I can't search through my music or anything.
Devices Tested:
Nexus One: Works!
Samsung Galaxy SII(Sprint): Works!
Samsung Galaxy SIII(T-Mobile): Works!
iPhone 4S(Verizon): Doesn't Work..
LG Nexus 4: Doesn't work..
I find it odd, that the N4 is not working properly. It's the same music library on all the devices! I've tried multiple music players, including a few paid-for apps. All with the same end result. Is there a workaround for this? Is there something wrong with my bluetooth module(or whatever)? I understand this car model seems to be picky when it comes to bluetooth, and one of the biggest reasons I came back to Android was because the iPhone just did not cooperate with the Mazda3. Like I stated before, the audio works, and it's fine, but I can't access it or see whats playing on my car's display unit.

Bluetooth calling / contacts in-car

So I took delivery of my shiny new Nexus 4 yesterday at work and as soon as I got in the car I paired up the bluetooth. Then somebody called me and the steering wheel controls wouldn't answer the phone. I've tested this several times now and that seems to always be the case. If I initiate a call from the phone though, it does relay the call over the bluetooth.
Secondly, the car cannot see the contacts in the phone. It just either tells me that 'no phonebook is available' or 'the phonebook is empty'. The car has never asked me for permission to read the phone book, even though I have unpaired, factory defaulted (the car B/T) and re-paired several times.
I had similar issues with my HTC Sensation when running 4.2 but the Sensation and car worked flawlessly together when using a Sense-based ROM.
Does anybody have any fixes for these issues? Not being able to use the car controls is a bit of killer to be honest. Not displaying the phone book is not great but at least if the car can control the phone I can use it to answer calls. I tried installing Bluetooth Phonebook but it didn't seem to make any difference.

Radio out car if using stock radio would really help here. I have JVC in the double din in the Saab and an eclipse in the wrx. JVC works as designed most of the time after the new update. Eclipse does not support PBA protocol. But controls work (minus pause on Google play app)

This one is still frustrating me. I have discovered that if I initiate or answer a call on the phone itself, it plays through the car speakers perfectly but it isn't possible to control the phone from the car controls.
I believe the problem is at least in part that I haven't had the pop-up on the phone with the car asking for permission - I did see it once after leaving the car but when I sent to activate it, the prompt disappeared.
So my question is still: Is there a way to force that permission setting, and if not does anybody have a workaround?

I'm in the same position
I've had my Nexus 4 for about a month. It worked fine 100% with my car till (coincidentally??) I went from the stock kernel to faux123's.
I have a 2008 Audi A6, which only allows voice - no option for streaming music across unfortunately. The phone paired, I Ok'ed the request to share call history, checked the "don't ask again", and I could make and receive calls from the car's controls. So far so good, just like my previous Gingerbread phone.
I don't think the new kernel was to blame - could it have been a google apps update? - but since then I can delete and re-pair the phone, I OK the share call history and "don't ask again" option, BUT the car's controls don't initiate or answer calls.
I went back to the stock kernel, tried Franco's, just moved to ParanoidAndroid's latest ROM+kernel - with all the necessary wipes - still no luck with getting the car's controls to work. I can start a call from the phone, or answer an incoming call on the phone, and it will play through the speakers, but it's a royal PITA, as well as illegal and dangerous.
So, I guess it ain't the kernel, but I just can't work out what changed. I have frozen Google+, Google Search, plenty of reboots and wiping the pairing off both devices.
I've done a good few searches, and it seems Google have never had a really clean bluetooth stack, and Volkswagens/Audis seem to suffer more than others.

I have no problems with bluetooth, calling or music streaming, in my 2013 Ford Focus using Ford SYNC. I'm stock 4.2.2.

Check tune2air BT adapter from viseeousa.com. My mom let me use her car and I want to stream music in it but I can't seem to do it in her car. So I found a solution, bought the WMA3000A with built-in AMI cable and i have BT steaming, and able to control, read, ,display music using original steering wheel and head unit controls. You can also check and try the 30pin WMA1000 model which plugs into any 30pin iPod integration cable.

[Q] LG G2 Bluetooth PROBLEM please help.,

I have a toyota Camry 2011 which has a bluetooth system. No entue, just bluetooth. When I connect to it with both call and media audio enabled. DIsplay says streaming audio and immediately starts playing Lg Music app. Now if I switch to spotify or pandora, my car immediately pauses the music and then won't let me play spottify or pandora audio. I need help. I love this phone but I can't seem to get this work. I love streaming music.
Its almost as if Toyota keeps trying to connect to Lg Music app despite stitching to pandora. This used to work when I had and SG3. In that I could switch to pandora and no problems. I think the problem is that as soon as bluetooth connects LG Music app starts playing but I don't want it to.

If you're rooted, you can always freeze that app. I wouldn't delete it in case it's tied to something else. You could also try deleting all of the songs that are in LG music.

I don't want to get off topic, but you're right. This is the real problem. You can see it whenever engineers with "just show up" degrees are tasked with anything. The idea is a result of just getting something to work in order to pass a QA check. QA will typically have a couple of scenarios to run through and if the code makes it through the scenario, it's considered gold. No effort is extended to actually understand the context of the code being written, or the spec being written to.
If everything was written per the specification, there would be no interop problems... But writing a complete implementation might cost a bit more, so eff it.

I actually have a similar problem with my new LG G2 and 2010 Camry.
I can pair it as a phone device, but not properly as an BT audio device. It pairs as a phone and makes calls just fine, but as soon as I try to set it up as an audio player, the phone all of a sudden can't find the car's bluetooth. BUT it will still play audio through the car stereo with apps like Pandora, however, I have zero control capabilities from the car and it playback will stay connected. Stereo just says "No devices found".
I also came from a S3 and it worked fine as a phone and audio player with this car. Seems like the new phone doesn't mesh well with the stereo?

The audio quality of the G2 over a2dp is horrible just like the two phones by LG before it, not sure what the deal is

OP have you found a fix for this? Just disabling the stock Music Player?

Is any news or solutions?

The A2DP audio is great. Enable Apt-X? There is a prop trigger. This phone IS Apt-X capable, confirmed through logcat. Research before you down a product. Different paired products will always behave differently.

I have the same problem in my 2012 FJ Cruiser except Poweramp automatically starts even though the BT settings are set not to. Anything else pauses after 2 seconds.

True, but "there is an app for that".
Modified Spotify client with included TrackID fix. I use it in my VW Golf with my LG G2.
Use the latest version in this post http://forum.xda-developers.com/showthread.php?p=44108915#post44108915

I still couldn't find any solutions until now. Could you?

ask your audio manufacturer to update software, unless its old bluetooth and thus not feature supporting.

Spotify - no sound, no track info (steer buttons ok - play, pause).

Bluetooth metadata?

Can anyone confirm that song metadata shows up on their car stereo when streaming over Bluetooth? I have a Kenwood deck that pairs and streams fine, but metadata are never displayed. Before I take it up with Kenwood, I want to confirm that the feature does in fact work with other units (and thus isn't a problem with the phone). Thanks in advance!

Works with my Toyota Avalon.

It depends on the car stereo. In my work truck (300 series Hino) my Bluetooth connects automatically & I can just press play on the stereo to start music & the album art and other metadata show no problems.
But in my 2013 KIA sportage, I have to manually connect to the phone every time & open the music app I'm using & start playing music from the phone first. And I get no info about the music at all.
Frustrating to me, because the KIA stereo is by far the better of the two & a year newer.

So frustrating. This is the fourth phone I've tried with this deck (Nexus 5, Moto X, Nexus 5X, Nexus 6P) and just can't get metadata. Grrr!

Having the same issue with the Sony double din unit in my Ford Escape. None of the players I've tried show any song info on the deck. It works find in the iDrive in my F30 though.
Never had this issue with my Xperia Z3.
I hope someone comes up with a fix.

Both my 2013 Subaru BRZ HU and the Pioneer AVH-X2700 in my Sequoia work just fine with Google Music. Neither display album art but I don't think the HUs support that.

Works perfectly with my '14 Ford Fusion SE

I have the 128gb 6p and it connects just fine on my Pioneer FH-X720BT. Phone calls route thru the system and caller info is displayed just fine. However, my problem is that it shows the track info for the first song but when the next song plays it still displays track info for the first song. I can play through 20 songs and it's still stuck displaying the track info from the first song. It does this with Google Music and Amazon Music. That's sort of similar to your issue, anybody else have that?

I have that same problem with my Nexus 5x on my Pioneer DEH-8700BH. I noticed it only does the no song update only with music streamed via internet radio through several apps. The song name works, however, when the music is physically saved to the phone. Weird...
Interestingly, I have the prior version of this Pioneer radio in my other car and it works just fine at all times. It's the DEH-8600BH.
No fix that I know of. It's very frustrating, I called Pioneer and they blamed the phone, then I called Google Nexus and they blamed the radio. I am very angry and hope it has something to do with Marshmallow. It works just fine with my brother's Android with Lollipop...
Hopfully a patch comes out soon.

Works great on my 2012 Honda civic.

I was looking forward to a solution..
My stock Nexus 6P shows no metadata in my 2012 Volvo V50, however, when I flashed CM13, metadata shows just fine.
Honestly, I dont know if caller ID worked in neither roms but I'm going to try it out this weekend.
I guess the BT driver is the issue?

That happens to me on occasion. When it does, I pause the music ( I use the button on my steering wheel or radio panel) and push play again, and the current song comes up. I also had this problem with my Galaxy S4, but it happened more often.

fixed!
It's fixed! I flashed the February 2016 update and now my phone displays metadata on the car stereo!

I"m not rooted. Just unlocked the bootloader and ran flash-all from adb with the feb2016 update.

I just got my 6P beginning of June.
First thing I did was pair it to my Kenwood radio in my car (KDC-BT858U).
I am seeing the same issue where all the controls work fine, there is just no metadata on screen.
My 2 BlackBerry phones have not problems (Passport and Classic). Both these show the metadata always.
I then paired the 6P to a Parrot Mki-9200 and on this device the metadata does show up...
Unfortunately it looks like it is a compatibility issue...
I thought BT metadata is supposed to be a standard... should be backwards compatible...
or is there some settings missing somewhere in the code for certain radios??

Issues with Bluetooth Audio

I'm starting to think my phone is defective... Anyone having issues with Bluetooth audio? Paired it to 2 different cars of different manufacturers (obviously not at the same time) and the phone randomly disconnects and/or "lags" when it's playing offline Spotify songs. Rebooted and it didn't make a difference. Anyone else?

had no trouble pairing with my car and it connects extremely fast. way faster than my note 7 or note 4. using the phone as well in the car works great. might be your phone

No problems in my Acura as well. I like how you can quickly choose what device to play A2DP with. Very convenient. Try to re-pair the devices in both cars. Also, remember to clear the devices (as well as all past devices no longer in use), from the car's computer.

I am seeing some similar issues. PocketCast randomly pauses and restarts while streaming, Spotify instead experiences random volume increases and decreases. New 2016 Ram with updated uconnect.

No issues with my 2012 Mazdaspeed 3 - it actually works bettr than my Samsung phones

I had some issues at the beginning to connect to my Golf 2015 but after it worked out everything works great now.

No problem connecting to my 2012 Chrysler. Only problem is now I can not see any info streaming. Anyone have a fix for this. Spotify, Pandora or mp3

No problem with my subaru

same issue with my volvo

The last two versions of Spotify have been terrible (6.3 and 6.5) they both have bluetooth issues. I suggest trying to downgrade to 6.2 and see if that resolves the issue.
I couldn't control music at all with Bluetooth under version 6.3 or 6.5, they would work for 5 min then stop working if you need more directions on how to do this just reply here.

I am experiencing the same issues when connected to my aftermarket car stereo. I find that it is happening with local audio book files in two different apps. The audio gets garbled and cuts out completely, but the app keeps going, so no pauses. This is driving me crazy! Hopefully LG has a fix soon!

I lost connection to my BT speaker when I went out on my deck yesterday. That was never an issue with my G3. Its only about 20 feet.

Pretty sure it's Spotify....I've had all kinds of issues with Spotify since the last update. I loose button control in my Camry, and on my lg tone platinum headphones. Also the the widget quits working and the album art screen quits showing up... No fix yet

Problem could be with nougat!! Pixel users are having issues as well.
I know most dont speak about 7.0 or the V20 but We are currently the only one with 7.0 and the V20 which dont get much press.

Couple of things to try and narrow down:
1. Bluetooth hardware (4.2 BLE for us), so software/hardware versions of both bluetooth and radio unit for the host is the variable...
2. Bluetooth music choice (spotify, music player etc.)
3. Is location of app and/or music files on external sd card?
4. Ensuring theres a "media audio" profile on your BT connection. This can be checked by going to the BT settings of the paired device on your phone.
Personally I've had a good experience with this phone compared to the v10 or even the s7 edge. Music meta data displays on the host unit (aftermarket Pioneer AVH-X4800BS in a '13 Chrysler 200 S type). Audio and mic sound better than the other phones but i have no testing to prove it...
Please post your info and maybe we can narrow it. I have some tech experience dealing with this so I'll try and help
Here's my setup:
1. Pioneer AVH-X4800BS. BT hardware 3.0, software C406 (stock software, needs updating) and radio unit firmware 08.15
2. Spotify and LG music player
3. Downloaded to internal sd card. Streaming as well.
4. Media audio profile present and activated.
Cheers
Edit: I also was experiencing the audio skipping and music player unresponsiveness prior to the v20. My initial guess is the music app goes in the foreground and doesnt get almighty priority treatment that nougut should be giving it if all the above is setup correctly.

An update to my issues as well as my setup to help things along:
On travel last week, my rental car was a Nissan Versa (puke), however, streaming bluetooth with spotify 6.5 worked flawlessly.
Came back to my beloved Ram, cleared both my phone and Uconnect bluetooth connections, repaired my device, and now I am seeing no issues with bluetooth streaming, either spotify or pocketcasts, with the exception of no album art or track time counting. It shows total track time, just no progress.
I believe my issues are with the UConnect system, as it has been a pain in the rear since I bought it last month. Sirius XM resets constantly, cannot connect via USB and Bluetooth at the same time and select USB as the source, etc. (was the same with my iPhone 6 Plus)
My setup:
1. UConnect 5.0 (RA2) Not sure what version of Bluetooth
2. Spotify 6.5 and Pocketcasts
3. Downloaded to internal SD card and streaming
4. Media audio profile present and activated.

I have a 2014 Buick and have the same issue. Works fine then will beggin to studder. Doesnt matter if is local mp3 or streamed from google.. However, as i type, it is the same app. But I am doubtful that is the issue as i get delayed text messages on the vehicle as well. If it is a defective unit i am bummed cuz I just dropped it yesterday and it now owns a a gnarly scuff, took the drop well tho.
I have an LG Urbane as well that also experiences some lag with inbound alerts.

Having streaming issues (DI.FM) in my 2016 Mustang. Stutters, and skips. I'll try to re-pair and see if that works. My S7 Edge worked great, kinda frustrating with the V20. I've also cleared the s& from the Ford Sync. LTE is very strong during my whole commute.

So after I googled a bit more I found a suggestion and it worked for me. Basically go to settings > apps > system apps > bluetooth and force stop the service and clear cache then reboot.. Been smooth since, not sure if this is a permanent fix but if you are having issues its worth a shot.
