[Q] Bluetooth, Car stereo, track names not appearing

Hi,
I have recently switched from an S4 with 4.4.2 installed to the new note 4. When connecting to my car stereo with the S4 via bluetooth the track names of songs playing in the music app and pandora would show up on the deck.
On the Note 4 i have no issues connecting to the deck but now theres no track names.
Is this to do with android 4.4.4?
Any ways to fix this?
Thanks in advance.

Seems to be so many variables in getting this to work. Always had problems with my Note 2... Works perfectly with Note 4 and Ford Mytouch Sync.
Try deleting the pairing on both sides and recreate it.

I thought i tried that but ill give it another go.
No one else have this issue or can say it definitely works with pioneer car stereos?

Didnt work

my pioneer head unit was the same, also i couldn't control it with the head unit.
I ended up updating the firmware on the head unit and it solved the problem, check to see if there is a firmware update for your headunit.

The problem is actually with the car stereo. It probably still runs Bluetooth 1.2 or something. I have the same problem in my 2012 Mazda 3. It has a dated Bluetooth. All I see is BT Audio, however it works fine on Ford sync and cars with more recent BT versions.

I have... inconsistent performance with this. If I am using the Play Music radio functionality, everything seems to work well. If I'm playing through an album though, it seems to get "stuck" on the first track played. The track duration updates but the track name does not. Pausing and resuming will get it to update.
With the same car and my Nexus 5 running the same Play Music version I do not run into this issue.

I've got a 2012 Honda Civic EX with the factory iMid (not navigation) system.
Was using an HTC Evo 4g LTE with a custom 4.4.3 ROM and was able to get track names and control music from steering wheel and connected via bluetooth.
Got Note 4 and lost abilty to see track names / artist info. I can still control the phone via steering wheel.
Unfortunately, Honda issues no updates for my factory stereo. If I go 3rd party unit, I loose steering wheel and bluetooth integration with the onboard mic, etc.
I am hoping that Lollipop will correct some of these things or that Samsung will issue a fix. I've seen a lot of posts around the web where people are having the same issue: prior phone worked fine. New note 4 phone lost track names. This was affecting lots of car manufacturers, factory stereos, 3rd party stereos, etc. Hard to narrow it down to one issue, other than all new notes having a new BT stack.
Just throwing my experience in the mix.

dlitwin,
Take your car to Honda, some Civics/Accords/CR-V, etc have an update for the Handsfreelink module.

Well, a quick update here. My T-Mobile Note 4 received a system update yesterday, and after that the Bluetooth works as expected with my car.

Not really a stereo problem if the thing that changed was the phone. It should be backwards compatible.
Hopefully theres an update in the works to make it come back. Its illegal here to touch your phone while driving and showing the track names on the deck helps with not having to touch it.
Might have to look at using NFC on my cradle to make the screen stay on, turn on bluetooth and connect the music app.

Awesome! In australia we get updates late usually so maybe by the time you have lollipop ill get that update

Still nothing. I got an update but it didnt work. pandora has updated and no good.
Anyone found a fix?

First off I apologize for bringing up an old thread. I recently purchased the Pioneer DEH-4800BT head unit so that I could leverage the Bluetooth capabilities. Everything works great, with the exception of the unit reading my music library via Bluetooth. If I restart my Note 4 and then connect it via Bluetooth to the Pioneer head unit, it reads the library and allows me to browse my music as it should. However, if I turn off my vehicle thus disconnecting the Bluetooth connection, the unit will not read my library without me having to restart my Note 4. Has anyone ever encountered this? I have a feeling there is something on my Note 4 preventing the unit from reading the library a second time without restarting. Unfortunately hours of Google searches on this subject have left me with no solutions. What can I do to fix this? Thanks in advance!

Eonon Android 5.1.1 bluetooth issues & canbus issues

hi guys
new to the forum, hopefully someone will be able to help me
my unit has stock MTCC-KLD6-V2.97 Aug 02 2016 with a RK3188 and 1024x600 screen
Firstly the Bluetooth is not working, quite a lot of apps hang at the part where it try's to turn the BT on, especially one app i really need to work.
I honestly don't know what model of BT chip is installed in the head unit, apparently its BT 4.0 as listed on there website
I have been into the factory menu and changed the BT from WQ_BC6 to WQ_BC6B (as suggested somewhere in this forum) but it has made no change and the BT is still hanging at powering on.
Eonon have told me that the Bluetooth only work with devices that don't require a pin and the radar detector device i need to connect does not require a pin but still it does not work.
Not quite sure if eonon has set the setting wrong and i need to change it or i need to goto a custom rom or I need to pull the unit apart to find out.
Found someone else having trouble getting there ALPconnect app to work aswell on these units, in know ALPconnect wont work on older unit like the 4.4.4 as they only had BT 2.0 and the ALP BT only supports 4.0, but this android unit has 4.0 so it should not be a problem but it is.
sterod said:
The app I use, ALPConnect, does the exact same thing. Fortunately, the hardware on mine includes a hardwired speaker and GPS setup that work standalone. The benefit of the app was to get a nice big visual notification of a trap, as it would come into focus, duck the audio and play an alarm. It would also report the frequency of the radar and the type of laser hitting me. While I can get by without all that, I can't have the music blaring like I usually do, as the little speaker is only so loud and the Joying head unit doesn't have Mute Input wire to duck the audio.
While this is going slightly off topic, you may want to look into the AL Priority, it can interface with your V1 too and you will also gain laser protection. This thing has saved my a** countless times and paid for itself already many times over.

Secondly the control menu in the android head unit for accessing the cars buttons via cambus does not work, all steering wheels button seem to communicate back and work, but i cannot set my clock on my mazda 3.
Also have noticed that the radio wont mute when notification occur or when using other apps like google maps, no way to set the different volumes in this stock rom. Have played around with the factory menu volumes but it makes no diffidence.
Is it viable and worth changing to a different ROM, like Malaysk? or should i message eonon?
any help would be much appreciated
thanks

I'm having exactly the same issue with a Pumpkin MTCC-KLD6-V2.91. (RK3188/1024x600)
The device I want to pair with appears in Bluetooth settings (with a phone icon?) but connecting to it does nothing. It's just a Bluetooth SPP device, like so many other devices.
Malaysk's ROM (from 7/25) doesn't change anything here.
Any suggestions would be most welcome.

Waiting on a reply from Eonon, but initial news is not good.
Some serious BT issues in this model the MTCC
Anyone know if any Malaysk's Rom's avalable for the MTCC-KLD6-V2.91 that have no BT issues

I'm having the same issue, though my unit (MTCC KLD6) does not show any devices at all to pair with, and the car unit does not appear on my phone.
I'm wondering - if I take a usb BT dongle and attach it to the usb cable, would that work?

I think it might be another issue with your BT, it should connect to your phone at very least.
Have you had a look in your factory menu to see if the MCU has the Bluetooth option set?
Password for me was 126
Unfortunately the unit does not support external USB Bluetooth and probably never will, unless the manufacturer MTC/Klyde adds the required drivers to the unit or a Awesome developer by some stroke of luck here adds it to the unit. I doubt to see the feature in this unit

Thanks for the reply. Yes, i checked to make sure Bluetooth was enabled in the system settings. I've tried a few of them (change setting, reboot, attempt pairing), i guess the next step is to try them all one by one to rule that out. I've sent an email to the seller to see if they have any ideas.

The vendor told me to connect the Key-1 & Key-2 wires from the canbus to the car, not sure why they'd think that would solve BT issues?

Did this fix the issue? I'm unable to see any Bluetooth devices and other Bluetooth devices don't see it.

Sorry to dig up an old thread
I have the Eonon GA2180a (android 10) - and having similar issues to here
I want to pair a bluetooth remote (read, steering wheel controls) to the head unit, but the bluetooth search just shows blank! I can connect to it using my phone but it appears some things are hidden to connect to with these android units? Looks like the bluetooth 'app' is the only way to connect too, theres nothing in the android settings to access a bluetooth menu or anything.
Did anyone get anywhere with this ?
cheers

I experience similar issues with the song info...on multiple devices, ranging from each major Android version since KitKat (I use my Evo 4G LTE from time to time). That's more of a Honda issue, honestly.

GS7 Edge was working fine though. Both on marshmallow and 7.0. Either there's something up with this phone or it's 7.1.1. My dad's iPhone 3gs works in my car fine as well.

Call choppiness on Nissan Maxima 2014.

No sound quality issues so far. Connecting to a previously paired device did not work a couple times but that has always been an issue for me on Android versions. Once I unpair and reconnect, it works.
In my car, I am connecting to an Mpow Bluetooth dongle plugged into my AUX jack and the sounds seems much better separated than my Nexus 6p when it is on Bluetooth. U11 is also clearer.

Kia Sorento SX 2013, streaming BT audio and GPS navigation flawlessly without problem.
On my Honda Prelude 2000 SE with custom Kenwood deck, HTC U11 also streams BT audio beautifully.

i have no problem what so ever, music,phone,massages,song info,email,etc... ,everything is fine

Hello
I have also these connecting problems with my Mercedes GLA and HTU 11, It will never reconnect when I start my car. I have to search always on my phone for Bluetooth devices and then connect manually. Before I had with the same car with Galaxy S8, LG G6, OnePlus 3, LG G5, Huawei P9 and all of them were working fine.
I think it's the well known Android 7.1.1 issue and hope an update will coming soon...

Seat Ateca infotainment doesn't import contacts from HTC U11 via Bluetooth
I have Seat Ateca 2017 (May) and when I first connecting (paired) my old HTC One M9 (Android 7.0) with car infotainment (IT) everything (Phone) works fine, contacts were imported, details of contacts were imported too (names& fotos of contacts) etc etc.
Now I have new HTC U11 with Android 7.1.1 (Android security patch level August 1, 2017 - software number 1.27.401.5) and car infotainment can not import contacts when it is connected with HTC U11 via Bluetooth. I can use car IT for talking, dial number but can't see name of contact and messages.
Anything similar?

I have trouble getting my U11 on 7.1.1 to connect to my bluetooth work headset. Never had an issue on my HTC 10. Sometimes even turning BT off and on again won't fix it and it will be stuck forever attempting to pair with the headset. Restarting fixes it.

Seems to be working fine for me. I connect it to my Pioneer 8890BT head unit.

I found the same the u11 just works perfectly whereas the 10 had weird micro skipping/cut issues, even started using my old Nexus 7 (2013) in the car to stop it from bugging me. So happy I upgraded to the u11 even though i still have to pay for the 10 till May lol.

I have a Motorola Bluetooth adapter because my older car has no Bluetooth and I can have the phone,and only this phone within inches of each other and get the Bluetooth stutter and cut outs. No connection troubles tho.

I have an aftermarket Sony car stereo and works great with Smart connect and the Sony app. Absolutely no issues with bluetooth for me. Works great on my PC and my JBL Charge 3. I don't think it is the phone or the Android version. Unless it is Androids job to make it work perfectly with your device that you are having trouble with? I don't know, just glad I am having such a great experience. Bluetooth works much better on my U11 than it did on my HTC 10.

"seicane" aliex - PX3 7.1.2 Bluetooth music A2DP quality poor

Hi guys..
Well first of all how I wish I'd checked these forums first before buying as I wouldn't have, second I wish I'd at least bought from the UK as I'd get some support. But hey ho I didn't and I'm stuck with it as returning to china seems to risky after the message suggested returning at a value of $70 so they don't get taxed and also making sure its sent by EMs so it doesn't get lost in transit like many units do at customs!!
So I bought what seemed to be an all singing all dancing unit from seicane store on ali express, for my seat ibiza mk5. According to the system info via root check app it's a px3, 7.1.2 android, rock chip, rk30sdk.
Amongst many other problems my main one is the Bluetooth audio quality over A2DP is horrendous, and it's not an amp problem as over aux or USB it's perfect. I've been looking at airplay using air bubble app and personal hotspot but it's too long to load and unstable I only drive 15 min to work so just want fast music to my ears! I've considered getting a Bluetooth transmitter and sticking it in the aux input but not ideal.
Anyone got suggestions as to what the issue may be and if it can be resolved?
Thanks in advance hope I can get this stable one day!

mine is also horrendous, and I also have a very short drive. Connecting a hotspot and launching app and getting a song, takes just too long for me. I'm basically already at my destination by the time I get it up. My workaround was to do what you said, and get a bluetooth transmitter and sticking to the aux, because aux sounds fine, but just bluetooth over a2dp sounds so bad, and has this distorted high end sound. This solution worked for me for awhile, but the only downside is you don't get song information on the head unit to display, which is a tad annoying for me.
I've contacted my radios reseller, and they're just ridiculously helpless, all they do is keep sending me a "software" update to fix it, but it does nothing. I've been searching for over a year for a solution, but have found nothing to fix it, other than what I just said. Problem was still there even when I used custom roms. SO I don't really think its a software issue, maybe some kind of hardware I can replace or modify, but I just really have no clue.

Yeh I've ruled out airplay as an option,
you've got me interested though as you're in a similar boat as me so hopefully can help, do you have the exact same unit for an ibiza or?
And yes thats exactly whats annoying me not getting track info, may as well just use the original head unit if i get a bluetooth transmitter!! which transmitter did you get? i've got a really cheap basic one years old and its got a high pitched whining noise in between song skips so its there just muffled out by songs playing, I'm wondering if thats probably just a cheap receiver I've got..
I'll try get somewhere with the hardware see about a new bluetooth module but no idea on the interface would be total guess work and risky at that, not even sure how to safely root this one.
Other issues i'm having which may be common and you may know? I got a dash cam which cam with a yellow RCA, an Acc+ wire, a ground wire and a 12V wire.. i don't understand why its got an Acc+ and a 12V, i thought similar things both transmit power just one off the ignition being on only? theres no 12v out wire on the head unit except 'cam pow' which I've tried to no avail. I plan on recording direct to the SD card on the camera.
Subwoofer out, does this work on our units? i bought it because i plan adding a 4 channel amp for F/R speaks and a sub amp for a single sub.. but does the rca not work / no amplifier control over it?!
Cheers hope to get somewhere with this as i feel a bit down that its not all singing all dancing like i expected lol.

i have a Seicane with Android 6.0 already, which I dont really have any problems with, but it is not PX3

Well the 6.0 version is totally different hardware

it is a known issue that no one seems to have a fix for. Im having this same issues with my PX5 Dasaita unit and had this issue on a previous Xtrons unit aswell. I believe it is a problem with the bluetooth drives not supporting the higher bitpools of recent bluetooth updates hence the bad quality. Ive even tried installing a USB bluetooth dongle but could not get the unit to recognize it.

Well I also have a Dasaita PX5 and I definitely didn't have a problem on that one. I would listen to Bluetooth audio on it pretty regularly.
Quick from Hot Audio did email me and ask about it, saying they had heard complaints, and sent me a new harness, but I haven't needed it

Well i've gone an ordered a car play dongle, so hopefully that will be a solution for good radio and a more functional nav at the same time.
Any tips for the dash cam guys? i ordered the 3 cable power one rather than a usb to keep the slots free.. not sure where i should hook them up to. (12V yellow, Acc+ red, black Grnd), i've only got an acc+ on the back of the harness and ground i made an earth wire to the car. Left the 12v off and it doesn't turn on. but my unit doesn't have a 12v, only acc+ or cam pow.

Got a pic or link to the camera you got?

So i have this camera..
https://www.aliexpress.com/item/140...32812106756.html?spm=a2g0s.9042311.0.0.MXwOS4
and this unit..
https://www.aliexpress.com/item/Aft...32827061575.html?spm=a2g0s.9042311.0.0.MXwOS4
The seller said to connect acc+ to acc+ on the unit, 12v to the cars 12v and grnd to the cars ground. I made an earth for the ground just to a screw towards the rear inside of the dash, but not sure where i'll safely take 12v from? especially with the car having a can bus if i splice any wires that may cause an error? Surely these units put out a 12v signal somewhere?
heres the wiring diagrams... https://ae01.alicdn.com/kf/HTB1z7DmnMn.PuJjSZFk763_lpXaZ.png
Also another Q regarding using an external amplifier for speakers and a sub.. is there an issue with the actual volume sent to the amps and can this be resolved? depending what input i give the head unit the volume differs, aux a lot quieter than usb stick or bluetooth.. but even both of them at volume 30 neither are really very loud where you here the speakers distorting, with a standard radio or branded head unit towards top end the speakers would distort so i can set a 'safe' max limit, my concern is the android head unit will limit the amp? and i've seen no info on rooting these units for viper4audio if that would help.
Thanks
Edit: how would i check if the 'cam-pow' wire is putting out 12v with a multimeter? just hold one probe to the wire and touch a ground point with the other?

BT & USB Support on PX5
Guys,
Sorry to tell you, the ROMS are very stripped down and as a result, the only support will be for the listing of BT modules that are on the main board and only for the ones list in the setup. You will not be able to add an external usb BT module to the head unit, it will not reconize them, and therefor will not work. Same with other USB devices. All support has been stripped out of the firmware. Some of these company's are getting slick enough to modify the firmware even more to only support devices that they sell, locking you into buying there junk. Good Luck! I had a BT problem with a Seicane Head Unit, and tried every possible, BT usb module only to find out what they do. Anyone want to purchase BT usb modules cheap!!!!!!

Bluetooth: Connecting to only the last used device?

I installed an Atoto S8 (2nd generation) head unit in my car, and I'm noticing that it only reconnects to whoever drove the car last.
For example, I usually drive the car. But when my wife drives, we need to manually go into settings to find the list of paired devices on the unit and then click on her phone to connect. After that, it will auto-connect whenever she drives until I take the car. My phone won't connect anymore unless I go into the list of paired devices and do that same thing. Silly and annoying because we share the car sometimes and have to keep track of who drove last if we want our phones connected.
I reached out to Atoto because their linux-based F7 didn't do this (I owned one previously), it would reconnect to any previously paired device automatically like any head unit should (obviously most recent first, but then if not found move on to another previously paired). They said the Android based units don't work like that, then gave me a silly reason for it that didn't make sense (something about security unlocking which the F7 doesn't have to worry about).
I'm wondering, do all Android head units have this issue or is it unique to this brand?
