Bluetooth issue in car

Whenever I connect my phone by Bluetooth to my car's stereo, only the front speakers work, nothing from the 2 rear speakers. I've tried adjusting the fade and checking settings in poweramp but still nothing. I'm not sure if this would be an issue with my phone, the ROM, or the car audio system. I'm thinking it's an issue with the car's audio but I figured I'd ask here in case somebody else has had the same issue. I am on liquid smooth 3.0 April 24th build with elemental x kernel but I had the same issue with my galaxy s4

I have no problem with nexus 5 and my car Bluetooth connectivity.
Make sure that your audio system, GPS and make and model are compatible with the bluetooth from the phone. Some other connectivity issues are that the car kit cannot decode the Bluetooth device that it is trying to connect. This decode means that the system cannot recognize the name. This is a frequent problem when devices have been upgraded. While your system may have worked fine before, upgrades can cause problems because the compatibility all of a sudden changes. This is an issue that has not really been addressed by the manufacturers.
Another frequent problem that can occur is that the Bluetooth will connect but then it will not stay connected and only one speaker is running,. Many times this can be a hardware issue.
So the bluetooth device can connect but it does not work properly. In this case there is an issue with the stereo connection to the Bluetooth unit. There is nothing actually wrong with the bluetooth or devices but this is a software issue. To fix it see if the manufacturer is offering any updates. If one person has had the issue then you can bet that many people will have the problem. This is a problem with the car kit software as no matter which phone or earpiece you use the audio will not play from the speakers. Check that the vehicle supports bluetooth audio as some only will support bluetooth phone calls. These are 2 very different things.
Most of the time, look into the settings for the bluetooth and the car system. If the car battery should die then the system may reset to the defaults. This means that all of the current settings will be lost and need to be reset. Not only will you need to check the settings in the car system but also in your phone or other bluetooth device. In order to correct the bluetooth settings the device will need to be connected to the computer.

I have an aftermarket Kenwood double DIN deck with Bluetooth 2.1. It connects perfectly fine, shows up with Nexus 5 when pairing, shows the song title, shows the name of the person calling... It works great when plugged in through the aux port, but of course doesn't show me any information that way. When I had the S4 it showed up as SGH-M919. It stays connected just fine and I had it playing for a while before I tried turning up the volume and noticed it didn't sound right and figured out the rear speakers weren't playing.
I just checked and noticed there is a somewhat recent update on Kenwood's site but it was still about 3 weeks before I bought the deck... I'll try doing that though. (edit) just checked again and the update isn't for my model, there's no software for it
Thank you for answering since I'm pretty sure now that it's a problem with the stereo and nothing to do with Android lol
Kind of embarrassed to admit it but...I did have Car Toys install it so... they probably didn't do a very great job. I knew I should have had either Best Buy do it or tracked down a friend that could do it. Oh well

Bluetooth Issue

Hi Folks,
Anyone had any similar problems? When my Z5 is connected to my VW Golf it constantly disconnects and reconnects, tried rebooting the phone, un-pairing and re-pairing still no joy
Just wondered if it was a bug sony needed to be aware, it's as if it's a power save feature that turns it off and on?
Cheers in advance.

Mine stays connected to my van fine

I use one of these in my car -> http://www.amazon.com/SoundBot-Bluetooth-Hands-Free-Wireless-Streaming/dp/B00RH29CJO
No problem so far, it stays connected

I´we got the same problem with my Z5 and Pebble Time

I also have bluetooth streaming issues. Connections initiated by the phone seem to work fine. Those initiated by the car do not. Have zero issues with a Nexus 5. I believe the issue may be related to the "Throw" service.

My Z5 only connects to my Nissan Qashqai 50% of the time. My previous HTC M8 would connect every single time, but Z5 has to have bluetooth turned on/off to work with the car. It's incredibly annoying and I hope it can be improved with software

Sony will probably have to fix it in next update...

I have the same issue with a garmin watch but only since the update I had yesterday, same with the car stereo again since yesterday

Tried disabling the "throw" function and it's still doing the same.... really annoying !!!
Hope Sony are reading...

My Bluetooth keeps my device awake, which renders my Android Wear kinda useless

I have a 2014 mini and the Bluetooth doesn't have any connectivity issues, but I definitely have bugs with music skipping, especially if I have maps open or something. Better than the initial 5.0 Bluetooth bugs but still really annoying. Probably my main gripe with this phone so far other than the fingerprint scanner

I have exactly the same issue as the OP with my garmin watch it connects then disconnects every 5min or so, whats weird is if i unpair and repair the connection is good for about 3hrs then starts playing up...
I also have a nexus 6 which i've tested with lollipop 5.1.1 and marshmallow and it works perfectly, my HTC M8 i used to have did exactly the same issue's as this sony, its got something to do with the trusted device settings i think the nexus doesn't ever ask about trusted devices both the HTC and this Sony do so it can't be just coincidence...
Is there anyway to disable the trusted setup on the device ? Garmin are saying to connect via there garmin connect app and don't actually connect with the phones bluetooth directly, i've tried that still doesn't work properly... frustrating...

I also have the same problem in my BMW.
Additionally, when I start call using built-in handsfree it suddenly switches to the phone's speaker then after 10 second back to handsfree.
Hope Sony fix this soon.

Does anyone know if its possible to install a apk or whatever it needs to be so that you get rid of whatever modifications sony have done to the bluetooth process the only reason i ask is i know through my nexus 6 that the bluetooth works perfect from google so replacing the Sony setup with the pure google setup should cure the bluetooth issue's or if there is anyway to disable the trusted devices issue that i'm sure is causing my bluetooth problems this is annoying me enough to consider getting rid of this phone... Excuse me ignorance i'm not clever enough to understand if this is an impossible task...

Don't know if this will work for others but last night i unpaired everything bluetooth on my phone switched the bluetooth off restarted my phone switched the bluetooth on and re-paired and now the 2 things i had issue with are working flawlessly since about 6pm last night... ???

Similar issue with pebble time, every so often it disconnects. My only doubt is which of the two is failing the pebble or the phone.
No problem with car in-calls or audio bluetooth.

I have a Z5 and I have pretty much the same issue with a 2010 Jag XF, phone connects via BT for a differing period of time then disconnects, sometimes reconnecting sometime not.
I've not had this happen during a call, and not with other Sony Xperia Z's I've owned.
Also I don't appear to have this with other items connected Via BT.

'I aslo have problems with the BT. The z5 will pair with my garmin edge 520, after that it can't find it no more and can't connect.
With my Stereo amplifyer, NAD D3020 it can connect as it does not require pairing but the connection is poor and i get alot of artifacts when i play music over it.
For the Edge 520 it stops everytime it ask for Trusted device.
My phone is in for warrenty repair, Was for a cracked rear glass, but i told them about the problems with the BT too. The phone is on it's way back now. Hope this will fix the issue. If the BT don't work, the Z5 won't be usefull for what i want to do with it.

I know with my garmin, garmin told me not to connect with the phone directly just the connect app, weirdly my watch has been working perfect for about 3 days and now this afternoon is playing up again I've installed nothing new or changed any settings baffling

Similar problem here with my Android Wear and my Cartio Strip. Continuosly disconnect, B icon on status bar disappear, then re-appear after 1 - 2 min.
Someone known how to disable throw?
Thanks

Xperia XA bluetooth software issues

I am encountering a minor problem in my XA. Whenever I connect to one of my two Sony music bluetooth devices, it just tries to connect to the other device I previously used. This is a problem because I cannot make it connect to the device I wanted because it just wants to connect to the other. This problem is worsened by NFC.
Any help guys? Thanks

Try using the smart connect app from the Playstore it's also on apk mirror under Sony mobile communications, it has various different options for connecting different Bluetooth devices and what to do upon detection. I use it so that as soon as my xa detects my sbh20 bt earphones it starts playing music with the music app

car bluetooth issues.

I'm wondering if anyone has problems with their car kit and xz premium.
I had a nexus 5X which always worked flawlessly regardless of android version or rom.
My car only allows headset connectivity, no stereo audio for music, just calls.
So here's the problem, since having the Sony I can make calls fine but incoming calls are troublesome.
I have to answer the call (car or phone controls) then switch from bluetooth to speaker (car keeps ringing) then answer again using the car controls, then swap speaker to Bluetooth on the handset. Then it stops ringing (car not handset) and the audio is routed correctly.
Any one have the same or found a fix?

I have never had any issue with the XZP for handling BT calls, switching music or any other apps in the Car. The only issue, though minor, is once in a while the Song info doesn't come in my car display.

Bluetooth music did not work in latest BMW 530i and Sony xz premium.
Sony xz worked good in the same car.
there is definitely something going on with Bluetooth and XZ premium

I haven't had any issues, I have been using it for both calls and music in my car and with various headsets without a problem. My wife has the phone too and hasn't had any problems with Bluetooth, connecting to either of our cars for calls and music.

My Mercedes BT media interface will freeze BT searching in XZP and stream doesn't work at all.

On my Kenwood unit, after pairing and allowing contacts share, some show up ok but I also have the majority showing name as blank and (No Number).
Not sure but going to try disconnecting and pairing again.

I have tried a factory reset of the Kenwood unit in the car but the issue remains.
Anyone got any ideas please? [emoji3]

There are some Bluetooth issues and it seems to be the phone. Had mine a week and a few times its not auto paired and on a few other occasions when playing music the track names are not updating on the car display. Never happened on my S6 with Nougat.
Bluetooth looks massively updated in Android O, hope Sony gets us the update quickly.

This is the problem I have. Got the latest 420d and the phone section works appart from no phone book access. No incoming call Ringtones. No connected drive app support and you cant play music from the phone using Bluetooth

Bluetooth issues have been bothering me since I upgraded from Xperia Z3 to XZ Premium. I have an android car head unit and the Z3 worked flawlessly for calls and media audio but the XZP will only give me media audio no matter what I try.

Bloody annoying or what?

I have the issue with my (both new) xz premium & renault megane. Phone connects to media settings, but not the phone settings then approx 3 mins later disconnects everything. It also won't show any album artwork/artist info. I hope Sony fix this soon as I'm about to scream.

Do the issues persist after the last updates? I plan to buy a XZP but I need bluetooth in my car so it will definitely guide my choice!

Hi. My XZP has updated to android 8 and now the Bluetooth works as expected ?

Oreo did not bring any change the problems persist

This did the trick for me: changed to BT AVRCP Ver 1.5
Spotify BT integration: Xperia XZ Premium G8141 (8.0.0 build 47.1.A.12.75) - BMW330e 2017
1. Enable developer mode:
system - about phone - build number - tap 7 times at "build number"
2. Set Bluetooth AVRCP to ver 1.5:
system - developer options - Bluetooth AVRCP Version - select "AVRCP 1.5"
3. Delete existing BT pairing and make a new one
Done!

Question BT audio trouble?

Anyone else finding that the Bluetooth audio can be a bit hit and miss, the audio has just fully cut out on me, but it displays as if it's still connected and playing via the headphones. I had no audio through either headphones, switching BT off and on, and rebooting headsets didn't solve it. Rebooting the phone brought the audio back, phew!
Out of the two headsets I have, My cheap Sony WI-C310's seem to work better, Using my jabra halo smart headset, it doesn't seem to connect media audio if it's also allowed to handle calls. I have to toggle calls off and just media to use Spotify with the headset (this could just be that headset being weird, think it got discontinued for not being great)
Anyone else having BT audio issues?
I've got a Huawei smart band 6 connected at the same time if that's a factor, it wasn't a problem on my original Nord though.

I have been facing the same issue for a while now, it's pretty random. There are times where it works perfectly and other times it either doesn't connect at all, or has a very weird delay, where it's fine in the beginning of say a video and gets a delay mid way through it. There are times where it only connects to one earphone, just issues all around. Also am using the oneplus buds z2, so honestly would expect it to work flawlessly with a oneplus device. The earphones work fine with other devices.

I've been getting random drop outs.
Both with connectivity with my car infotainment system and my cycle computer.
When I had my OP7Pro, never experienced anything of the sort when connected to these two same devices.
I've also tried enabling Bluetooth Gabeldorsche in the developer settings, and that didn't make a difference.
Will try changing the Bluetooth AVRCP version to see if that improves anything (currently set to the default of 1.5).
Has anyone else played with those settings and tested the impact?

Tested with 3-4 Bluetooth devices and no drop outs.
I notice that when I put the device in aereo mode the Bluetooth remain active, but in the latest days this problem doesn't happen anymore, maybe was a bug of the first fw, and after last update they have fixed?
