Bluetooth not working in the car - G4 Q&A, Help & Troubleshooting

Hi,
I bought a new LG G4 after using galaxy s2 for 3 years. I have ford focus 2012 car, the galaxy s2 has no problems with connecting and playing music in the car, but now I can't connect the LG to the car, when I am connecting it(with a bluetooth) its works only with calls, its not playing the music in the car systems,I tried to "forget" to car from bluetooth, tried to clean the cache, tried every thing that I found, maybe someone has another way to fix it ?

[Q] Car Bluetooth Audio Problem

I have a LG Nitro HD running on AT&T. The phone came pre-loaded with 2.3.5. The bluetooth phone part works as I can make and receive calls with my car (Suzuki Kizoshi 2010), but the audio over bluetooth doesn't work. The phone part works as I can make and receive calls. This is very important for me to be able to play the audio over bluetooth as I have a long commute to work and like to listen to my music. Any help is greatly appreciated. Thank You.
It's been about a month and still no solution. Has anyone else come across this problem?
I do not have this problem. I have a Pioneer X930BT headunit in my car and my Nitro streams audio over bluetooth (A2DP) to it perfectly as well as phone calls.
Have you tried streaming Sirius or spotify over bluetooth? I found that the only app on the phone that streams audio to my car correctly is the pre-installed audio app that comes with the phone.
I can confirm google music and napster stream great over bluetooth. I have not used spotify or sirius for android.
Are you sure your car supports audio profile?
I stream spotify, tunein radio every day through bluetooth.
Spotify actually pauses when bluetooth connection is lost which is great for getting out of the car. I wish TuneIn would do it.

I have had the same problem with my nitro, it will automatically connect the phone but the media (A2DP) seems to drop automatically after connection. I've found if I manually re-connect to the receiver both will stay connected.
(settings > Wireless & Network > Bluetooth settings > *tap device name*)
I, like you, use it every time I'm in the car so it's annoying but it's a fix until there is a valid solution like a update or properly built rom.
In your case I would delete all the phone profiles from the car memory and re pair them. A lot of cars have a seperate a2dp profile for streaming music and if you pair them seperately the car stereo thinks that it needs to be paired only with the cell phone while the phone says that is paired with phone and audio.
It is not a LG Nitro 4g issue. Updates/firmware would not fix it.

That seems to be your problem JoTomlin and Kaiser. Before I installed my new headunit in my subaru I had tons of issues with my captivate playing music over bluetooth because the car had seperate profiles for A2DP and handsfree. When I got my new headunit which has a single profile containing both A2DP and handsfree it all worked without headache on the captivate and now the nitro. This is a problem with your car stereo. If its anything like my subarus, it would prefer to connect to handsfree and it would have to physically disconnect handsfree to connect A2DP (I would have to manually connect via the bluetooth menu). I solved it by getting a tunelink bluetooth audio receiver so handsfree would connect to the stereo and to the tunelink at the same time. Eventually I got tired of that and bought a new headunit.
Apparently a lot of people have swapped out their factory Kizashi factory head units for something better. But again, you'll want to bug Suzuki about something like this.
FWIW, I can stream Pandora just fine over a VW headunit with factory bluetooth. I do have to sometimes to a reconnect/pair though.
Has anyone figured out this issue? I stopped using my Nitro for about 5 months and then just recently updated it with 4.0.4, but still have the audio issue. My Samsung Galaxy SII doesn't have this issue. It's frustrating because I really like the Nitro. The Bluetooth audio is a huge issue though. Any help would be greatly appreciated. Thank You.

Did you factory reset after updating?

Problem with 2 simultaneous bluetooth devices

I have been having a problem with using 2 bluetooth devices simultaneously and was wondering if there is a problem with my phone or bluetooth devices or if this is normal/expected.
I have bluetooth in my truck (2012 GMC 2500HD) that only works for phone calls. I also have a bluetooth adapter that I plug into the cigarette lighter for music. The adapter is capable of playing music and working for phone calls, but I have the headset profile turned off in my phone for that device so only the headphone profile connects.
On their own, each device works fine, but with both connected the vehicle bluetooth continuously connects and disconnects. Has anyone seen this before? How can I go about troubleshooting and fixing this so I can use both?
I have a stock GSM Nexus on 4.0.4.

In my Camry I use built in BT for phone calls and plug in a BlackBerry Gateway into AUX port to stream music. So 2 BT devices are connected at the same time.All is working well, meaning when music is playing and the phone call comes in, Nexus switches to the correct BT device. The only issue I'm having is that sometimes I have to manually connect to the Blackberry gateway.
Thanks for the reply. I was kind of afraid of that. Unfortunately it seems like it is the vehicle bluetooth that is the problem, the one that I really can't replace or do anything with.

Thanks for the feedback. I will do some testing with other bluetooth devices and my wife's iPhone to see if I can mount enough evidence to convince the dealer it is a problem with the truck and not my phone.

Motorola! You have a serious Bluetooth issue with the Moto 360! Please fix!

If anyone has another Bluetooth device connected while using the moto 360, it causes the other Bluetooth device device to act very odd. My example was tested on 3 phones and 2 different cars and that while my phone is connected to the moto 360 and cars Bluetooth, the sound is all choppy and horrible from my phone. (not Bluetooth audio from my car) You can't even get directions from Google maps or Here because the moto 360 causes the volume from the phone to become all choppy. Even when the phone rings the volumes are choppy from the phone. Once I unpair my moto 360 everything is back to normal. Looks like others are having odd behavior as well when connecting Bluetooth speakers and using the moto 360 at the same time but I have not tested Bluetooth speakers.
Please help Motorola cause this watch is awesome
Maybe you shall email their support group to give the issue report. I plan to get moto hint.in furture but this issue may stop me.
That's a Bluetooth/Bluetooth Low Energy problem. I had the same issue ever since I started using a fitbit with my LG G2, which syncs via BT LE. The 360 compounded it. I recall someone suspected it had to do with the ble implementation in the android bt stack, but I don't recall the specifics
Using the 360, fitbit and uconnect car bluetooth all day yesterday with no issues.
Google play music streaming.
CBS streaming radio
On device music.
No issues.
Try doing that again but using Google now or Google maps and report back
Using LG G flex, Motorola DECK BT speaker and moto360 and wasn't having any audio issues either. Played music for hours at work.

Every morning I drive to work with my Nexus 5 connected to three devices and stream music without issue.
Audi BT for Phone
Griffin BlueTrip for BT Audio
Moto 360
On the way home, I stream MLB games (well, up until last week). I check traffic via Google Maps to see the fastest route and I never lose Audio.
In following these threads, there have been a few other things to keep an eye on:
The #1 culprit seems to be custom ROMS and Kernels.
Others have mentioned leaving wifi on. Android tries to connect to open wifi networks, even while driving, and that can cut out signal.
Not one issue with Bluetooth on my end,and I'm paired to my LG tone all day everyday.
S4, cm11, play audio through speakers w/o issue. Most likely an issue with phone/ROM/kernel/car system rather than the 360. I've had three different 360s so far (various RMAs) all work/worked fine with car Bluetooth audio.
No issues here with BT connectivity. I have M360 connected to my phone, and my phone connected to my car BT audio.
Stream music via Amazon Prime Music app, audio came out great
Navigate using Google maps and the direction was spoken via car audio clearly while M360 does prompt and vibrate for direction as well.
I have no issues. Nexus 5 connected to my Moto360 and factory head unit (2011 Camaro). I stream Pandora, Google Play, and have spoken notifications.
I had my 360 for 3 weeks every day I connect my HTC m8 to my car radio via blue tooth. At work I connect to Bluetooth headphones and listen to music for about 4 hours a day. I have not had a single issue like the one you describe.

I have the issue, but not playing music. Mine is with phone calls. This is with the watch paired to a stock LG G3. The phone calls start out okay but a minute or two in it gets all garbled on both ends.
No problems here with my Sprint note 3. Actually navigated a few days ago with maps and it was fine
Can't Bluetooth-tether my tablet to my phone while the watch is connected. Also, if I walk out of Bluetooth range of my phone, the watch either doesn't reconnect when I come back in range, or takes a very long time to do so.
Same issue..
I do have the same type of issue with intermittent audio over bluetooth while in my car. It's find if my moto 360 is turned off, but when it turns on it causes issues. I had the problem on the old Moto X and the newest Moto X. I found other threads reporting the same issue.

I connect to my cars bt to and from work every day and have not experienced any issues. I'm using a stock 2013 Moto X 4.4.4 no root/mods.

Bluetooth issues after Update

My phone (LG G4) updated last night. Now when I try to connect via Bluetooth to my cars head unit the Bluetooth connects, disconnects, and reconnects over and over again. I tried restarting the phone several times and upaired the devices and paired them again several times with no help.
Any ideas??
Thanks
Phone is an LG G4. Forgot to put into original post.

I had this problem when I had more than one device paired over Bluetooth at the same time. For example, when I had my Fitbit paired with my phone and then I paired my phone with my car stereo, it connected and re-connected 3 or 4 times before it stuck. Since the update, I haven't re-paired by Fitbit. As a result, my phone pairs easily and the first time with my stereo.
I am having Bluetooth issues as well. Calls that I make from my car using the handsfree bluetooth built into the car (a 2015 car too) sound awful. It is garbled on both sides. It was fine before the marshmallow update on my G4. My wife's G3 got updated to marshmallow too, but it works fine in the car. My bluetooth headphones work fine too with the G4. Playing music over bluetooth in the car works too. It is just phone calls that are the problem. Unfortunately, it is a pretty big problem for me.
Any ideas on how to fix this?
Is there anyway to roll back without rooting?
Have you guys tried full factory wipe and repair everything again? There are a lot of things that could go wrong with Bluetooth. I have no problem with my 2013 car and my android wear watch. It was acting a bit weird before I applied the update!

Issues with bluetooth in car

Hello,
I recently got the P2. Awesome phone, even better battery.
I only have one issue with it. I always listen to music in my car with my phone, but for some reason it always has problems with bluetooth syncing.
When I get in the car, I check the settings and it looks like the phone is paired, but only the phone part (to make calls), but not multimedia. Music will still be playing on my phone speakers. I have to manually try and pair it 2-3 times for it to connect.
My previous phones were the Nexus 6 and Nexus 5X and they would not have problems pairing, they would usually pair within 5 sec of getting into the car and the music would transfer to my car speakers.
Does anybody else have this problem? I'm running the latest standard lenovo ROM, 7.0.
