[Q] EVO 4G + Ford SYNC/MyTouch: Poor Bluetooth

Hey All,
I have been scouring the web in hopes of answers and can find none. Evidently I'm not the only EVO owner in this boat either. I own a 2011 Ford Explorer with Sync & MyFord Touch (Fully updated). I pair the phone to the car it makes the connection fine. Begins the setup and sometimes will even connect and be recognized for a bit. But then the phone drops the bluetooth headset part of the connection. It appears (but I can't confirm) that Bluetooth streaming audio is still connected. There was a blissful 3 day window where it all just worked. Then it went to hell...... I saw one post where it said to switch the Bluetooth name back to "PC36100" and that didn't help. I saw another that said use a 4 digit pairing code and that didn't help either.
Its worth noting that I'm running Myn's Warm 2.2 rls5 with the stock & fully updated HTC kernel. So here's what I'm hoping to figure out:
*Have you had this issue with ANY car?
*Have you had this issue with Ford SYNC/MyFord Touch
*Aside from unpairing & repairing were you able to get around it?
*Is there a Kernel with a better bluetooth stack I should try?
Thanks for any help, many thanks will be given!

Unfortunately, the HTC bluetooth is totally worthless. I have a 2010 Ford Focus with Sync and it would connect and sometimes work for awhile, but people on the other line always complained of poor quality. And it wouldn't even connect all the time either. Lots of deleting and readding the phone.
Couple weeks ago I switch to CM7. Since CM has a bluetooth stack they built themselves and actually implemented correctly, I haven't had any problems pairing my phone. I can make calls, stream music, gps, etc and it is all fine. Always connects too. What is nice also is the audio will automatically stop if Google Navigation is giving directions or if someone calls. When I shut my car off and open the door, the audio stops and when I get back in it automatically starts again where it left off.
Basically if you want to use your Evo with a Ford Sync system, you'll need to run a version of CM.

Arg. I'm still waiting on my Explorer
On my 08 Explorer with Sync and Myn's RLS4, all is good. I turn BT off and make sure it is on before I turn the key. I stream audio constantly, and talk a bit. I literally just got around to putting on RLS5 today, haven't driven yet.
I partially agree with teamgreen02. It's HTC, not Ford. Does texting work with CM7? That would push me over the edge (or Explorer, pun intended)

It seems that there are a bunch of phones that have issues maintaining connectivity with the latest Sync system. I had to re-pair a BlackBerry to an '11 Explorer this afternoon. There is a backwards pairing procedure that may help rectify your issue. If you try searching for your phone from the vehicle instead of searching for sync from your phone, it has, in my experience, minimised connection drops, especially on the latest versions of Sync...
Btw, I am like the only tech at my dealership who really understands how to even pair phones to Sync, let alone diagnose the concerns our customers have described. There is also a system compatibility chart that we reference to determine if a particular device has been tested and verified to work with certain features of Sync. Last I checked (the October 2010 update) the Evo still wasn't certified compatible/tested...

Does anyone have any updates on this? My wife's Sync is working fine with her Evo but the sound quality sucks when she calls. Her phone isn't rooted.
I did update the Sync software from v1 to 1.1 (She has a 2008 Ford Edge Limited) but need to do further updates to the system since there are updates available.

Here is my experience/.02.
My wife drives a 2011 Ford Edge with sync....she has a stock Evo4g. When she bought the car 2 months ago, bluetooth seemed to work fine...now she is having the exact same issues everyone else is having. The bluetooth connects/disconnects and just plain doesn't work. I attempted to fix it and.....no. If i unpair from both the car/phone then retry to connect them, it connects for a second and when it tries to send the phonebook from the phone to the car, the connection dies. The phone still displays that bluetooth audio (not phone) is connected.
I then tried my Evo 4g (CM7) on her car...no problems whatsoever. Sync'd and connected fine...phonebook transferred over in about 5 seconds and everything worked great.
To note, my Evo 4g also works perfectly on my 2011 Infiniti G37...
So I think my example further proves that HTC's bluetooth software is likely the causative agent and is likely junk....root or die i guess =p
hope this helps someone

I rooted and installed MIUI and dont have any problems yet with sync.
Although,
I was looking looking to pull the bluetooth stack of the droid X which has the MAP bluetooth profile, that will allow ford sync to read and write text messages for you.
any ideas on how to do this? Or where to find in in the droid X?

2010 Ford Focus here, works fine for me. Using Fresh 3.5.1.

The bluetooth stack should all be dependent on what kernel you are using on your rom, so if you already have it rooted, try to change kernels and see how it improves...
as far as the MAP profile, i found this thread in the Q&A section, and it also recommends pulling the MAP profile (for text messessaging) from the motorola droid kernels.
I wish i knew how to do this.
I was hoping for someone to be able to do this for us
EDIT: I also found this thread:
http://forum.xda-developers.com/showthread.php?t=741332
its trying to get the MAP profile into the nexus one...
they found the new bluez stack had the MAP profile included:

I have not used sync in a long time in my 2010 escape, but I'm wondering if the text message function works as well. Any word on this?

No, the text messaging does not work for the unrooted Evo and it doesn't work for a rooted Evo under Myn's Warm TwoPointTwo RL5.

I Just had a 2011 Explorer limited for the past week as a rental and it worked fine for me (music & calls). I know this does not help much hope you get it going.

i had my EVO running fresh 3.5 and worked great in my Escape, i just switched to twopointtwo ROM and now here i am looking for a solution, not sure if its the rom or the kernel since i switched both..

got it working for a day but its disconnected again, im going to explain what i did hoping someone with more knowledge can help us SYNC users to connect bluetooth
used fresh EVO 3.5 for a while and worked great, then i got bored and changed rom to myn's warm 2.2 with the kernel included and bluetooth started disconnecting after 30 seconds or so...
i tried
ms79723's SBC for Netarchy's CFS More Aggressive 4.1.9.1 Kernel (v7)
Ziggy471 Warm TwoPointTwo RLS4 Kernel
they didnt work either... so heres the funny thing..
i wiped and reflashed a fresh version of the same rom (Myn´s warm 2.2), this time i didnt restore anything, no apps, no contacts, anything, left it clean.. then i paired it up and voila.. it worked for a long time in my ESCAPE, so i thought it was working and restored all my apps and data.. and to my frustration... its disconnecting again.
so does this have to do with the kernel or with some apps or what.

has anyone figured out how to get sync working with blue tooth messaging.

2010 Ford Focus. Bluetooth sucked with stock ROM and warm, dropped connection all the time. Works great with CM7. Definitely an issue on the phone side and not the car in my case.
I am also wondering if we can somehow get the text messaging working. I don't think its officially supported on any Sprint phones.

2010 Moutaineer here - never had a problem with Bluetooth on rooted stock EVO ROM.
Listen to music all the time - even the "call-transfer" functionality works fine when I enter the vehicle while talking on the phone.
Only thing is - I wish the damned thing would auto-synch for media-audio on Aux1 instead of me having to select the source all the time - anyone know how to do this?

2010 Lincoln with mytouch/sync and rooted with stock rom. No problems at all. Sometimes it gets a little static sound but I just turn my Bluetooth off then back on.

Think the problem lies with the Sense BT stack.

can someone help with bluetooth?

Hi Guys,
I'm having this problem that is driving me nuts, don't really know how to proceed.
I have a car stereo a Kenwood DNX8120, which has parrot bluetooth hands free. It has worked very well in the past on an LG, SonyEricsson and the Nexus One.
On the Nexus S (I bought this used and rooted with CM7, so I don't know about a stock model) the bluetooth connects, then after some time, like 20 seconds, it disconnects. I can play this game forever, it won't stay connected.
I can use one of two methods to connect
1- put the phone in BT discovery and let the kenwood connect to it, or
2- Have the phone connect to the kenwood.
I've tried both with the same results.
I got a.logcat and I see a whole bunch of red entries at the time this happens but I don't know what to make if it and I don't know how to grab these entries to a file.
I have also tried a phone wipe and installed infin1ty's ROM and also the latest CM nightlies. Same friggin result.
I see in recovery there are options to delete dalvik and data but I don't know if they'll help.
can you guys help?
Thanks

Tried another device. The actual hardware could be messed up on either device causing this. Try your LG again to the radio and the try another headset to to the phone. Last but not least try the stock Rom .
P.s. cm7 had an issue on the evolution where by was not given a unique Mac address which caused issues for me connecting 2 cm7 EVOs (they would over write each other).
Hope that helps

Hi Thanks for the help.
Both LG and SE phones still work fine. I'm unable to find another nexus s so I dunno if this particular one.
But here's a new discovery.
I paired them using the HU. Now when I start the car, the BT connects then after a bit it disconnects. Well now I can go to the *phone* and manually connect to the kenwood and the connection holds!!! I have no idea what is going on with the autoconnect but it can apparenlty hold a connect if I manually initiate it from the phone.
All this time I had been trying to get the kenwwood to do the manual connection (after the auto connection faills) and that never held.
sigh...

Have you tried a headset with the nexus to see how well/bad it works? Also are you on the stock rom? If so take it down to your carrier and ask if you can try it on one of their units.

[Q] Question about issues with bluetooth in EC07

Good morning fellow forum member. I've recently begun having some significant bluetooth connectivity issues with my continuum and Ford Sync system in my 2011 Fiesta. Now, before you start ranting about your loath for microsoft or Ford please hear me out. In theory, the Sync system, combined with bluetooth technology, is a great way to go hands free. It also allows for the coordination of the system and Pandora & Stitcher Radio on an Android phone.
Anyway, lately my bluetooth connection to my car has been causing FCs on my phone. They are the type of FCs that cause the "long-short-short-short" haptic feedback but doesn't throw a pop-up message describing the cause of the FC. So, when the feedback occurs the phone will sometimes lock up but it always disconnects the bluetooth. I don't use bluetooth in any other fashion so I can't be positive that it's not an issue with the car's bluettoth system.
With all of that said, is there an inherent issue with the bluetooth system on our phone? If so, is there a fix for this? I'm currently running the EC07-clean_new ROM. This was installed over the SCH-I400-EC07-FROYO-REL-PRODUCTION ROM. My broadband version iss:i400.0.6v.EC06, Kernel 2.6.32.9 and build SCH-I400.EC07.
Any help that you brilliant folks could offer would be much appreciated.
Thanks,
Ray

I run bluetooth constantly (it's the only way I talk on my phone, driving or not.) I've never run into this issue. Have you recently downloaded any new apps? I found that there are some apps that simply don't play well with our phones. Especially radio based apps (I.E. the issues a lot of us were having with gps based apps, or gps losing it's lock, after a while. Wireless tether 3.06 beta completely screwed my phone up... etc). The only other thing I could suggest is to drop your phone from the sync, and reconnect it... I do this with all my bluetooth devices at least twice a week as a matter of course. And if you want to experiment to see if it's sync or your phone, assuming you have bluetooth stack on your computer, you could connect it to your phone. Other than that, maybe find a friend that has bluetooth and connect it?

Thanks for the suggestions. The most recent app I have installed that uses a radio is the new Stitcher, though I have been having some issues with "My Tracks" FCing but I think that is another issue. Anyway, prior to your reply I found an app on the market called "bluetooth fix repair" It's free and I gave it a shot. I've also deleted the phone from my car's list and repaired them. So far so good. I have a bluetooth stereo headset I'll have to try. I probably have too many apps to begin with. I'll see about deleting some of the ones I don't really need.
Thanks again,
Ray

I think you should be good with rourine disconnect/reconnect. Asfor too many apps, the only thing rhat matters there is storage space. Android wint let you run "too many" at once. Itll delete from ram as needed. I was just saying that certain apps dont seem to play well with others. But that is an android issue, not your phone in particular.
I'm not here for a long time. I'm here for a good time. To hell with the red wine. Pour me some moonshine. - King George

I'm totally stumped here. Yesterday I decided to reflash my phone. I figured any issues might be ironed out. It must be an app issue, although it is going to be a PIA to uninstall then reinstall each app and test the BT after each app install. I thought that it might be the trailblazer101 car cradle, desk cradle or the sticher apps that were giving me the problem but that doesn't seem to be the case. Maybe I'll try replacing the BT files with the ones from eclair to see if I end up with the same trouble. Any idea if that might cause more problems? Are the BT files android version specific?
Peace
EDIT: I've not swapped the BT files from eclair but I did spend an hour or so listening to Stitcher radio via a bluetooth headset. It doesn't seem to be a BT issue. More likely an issue with the connection to the Sync system itself. Connecting via bluetooth is no problem in the car. It's not until I attempt to engage a function other than the phone that an issue occurs. I may try to reflash the EC07-clean ROM and see if there was something with the EC07-Clean_new version that I've been running for the last few weeks.

OK, the BT issue seems to be corrected. I flashed adrenalyn's EC07-clean ROM and that seemed to do it. Something must have gotten corrupted. So, issue resolved...i guess.

[Q] Nexus 4(MTP devices) and Ford Sync

Hey everyone, I currently own a Ford Fiesta which has Sync. I'm trying to shed some light regarding MTP(USB) and Ford Sync.
So far, my research shows that the Galaxy Nexus which introduced MTP, people would have their playlist get stuck at "Indexing" and you were not able to sync through USB (Bluetooth pairing works fine).
I've tried the regular methods of, factory resetting SYNC and doing a master reset on my car. Anyone have better experience with this situation? Advice?
As a background, the only music I have is Google Music. I currently have a couple albums in my device but the rest are uploaded. Tomorrow morning I'm going to try updating my software (which I believe is already up to date) but worth a shot. I have the Nexus 4 running (Android 4.2 [doy!])
Help would be greatly appreciated!
xRef: reddit ref

Selfless BUMP.
If this doesn't work is there anyway I can make a (Music)folder partitioned so that it will mount ?
I know currently there's not MTP to USB Mass Storage mode :/ but there has to be a way to get this working

How good is the Nexus 4 working with Sync? Anything to look out for or any tips you can provide? Gonna be trying it with my Ford soon. What works and what doesn't work?

I happen to have a Fiesta with sync... I've never tried plugging my N4 into it, though... I either just stream Pandora (get the Pandora app link if you haven't yet; it's awesome!) or play music from my thumb drive. If you'd like, I can give it a try in my car and see if I get any other results.
BTW, does your phone work with text messaging?

Pretty good... the sound quality is noticeably worse than my older phone, though, but it's not too bad. Pairing is a lot quicker I've noticed. Text messaging doesn't work, however... I know only a few phones do, though.

I'm just curious if you can get all the wireless Bluetooth functionality that Ford Sync claims? Such as reading of incoming text messages, voice activated calling, things like that. Does it work for you? I'm guessing by your question that text messaging does not work, sadly.

Here's a summary of my experience.
-Currently, MTP on the Nexus 4 makes USB Audio not sync, so you can't play music through USB (You'll get stuck at Indexing FOREVER).
-Bluetooth Audio works pretty well however you won't get info such as Artist, Song name, etc.
-Streaming audio through bluetooth doesn't let you do "Play Artist XXX or Play Song XXX" that USB Audio CAN provide.
-With that said, like someone said above me, you can use a USB thumb drive just fine to play a bunch of songs. If you have a Ford Fiesta 2012, there's a secret Secondary USB2 for developers which works PERFECTLY fine. (http://www.fiestafaction.com/forums/ice-car-entertainment/31647-second-usb-port-19.html)
-Sync can read your messages once it does come in but you have to press OK a couple of times.
-The Sync Messaging system is TERRIBLE. You cannot reply with a custom message. You always have to use preset ones. I really wish someone is able to hack the sync button to call Google Now or something.. that would be AWESOME.
-Using Pandora App Link works pretty well, you can skip tracks and pause it's awesome.
-Sync Services can be pretty useful. I recommend using downloading an app called Send To Car, which lets you go on google maps, type a location or business address and "share" it to Send to Car which then sends it to your car so you can navigate.
Sync isn't perfect, but it has an even share of good and bad. If you're in to buying a Ford Fiesta, I recommend holding off for the 2014 version which will support MyFord Touch. This actually allows AVRCP1.3 so you can stream audio track names etc through bluetooth.

Thanks for the information!

I agree, now that would be great.

Shameless bump.
So I found out today my friend's S3 is able to stream music through USB in his Ford. According to my car forums as well iPhone 5 users are able to do the same on SYNC capable cars. :/ I know these phones incorporate MTP style storage so why can't my Nexus 4 do it ): .

Hi darkamikaze,
Can you let me know what version of Ford Sync you are running? I'm going to guess it's an non-MyFord Touch system, which seems to have more support for the Bluetooth MAP profile.
I've got a Nexus 4 on order, and running the latest MyFord Touch system. I will report back if this seems to work any better.

Yes I have the Gen1 on my Fiesta'12 which I know for a fact will never get the better bluetooth profile which allows media info to be passed along to my fiesta's dash.
Still unfortunate that I can't get the damn USB-To-Nexus 4 working -_-; Forever stuck at indexing.

Just for everyone's information:
http://www.engadget.com/2013/01/07/ford-looks-to-go-the-android-route-with-its-sync-applink-system/
http://www.autoweek.com/article/20130108/CARNEWS/130109897
https://developer.ford.com/
It would be interesting to eventually see an app to interface with Google Now. Additionally, I believe that Ford Sync systems use the i.MX516 ARM with processorWEIMX: Windows® Embedded for i.MX Applications Processor. I could be wrong about the OS though. It would be cool if they made the OS code open source, imagine the possibilities.

That is fantastic news! I'm gonna try to dive into this right now!

Please let us know...
Another thing beside music is the calling feature. When I receive a call and wanted to take it on private then I should answer from the phone not the wheel button nor the dashboard screen but when I do so the call would still trans to the car audio. When I used blackberry before I used to answer from wheel/dashboard for car audio call OR I could answer from the phone to have a private call on the handset.
Any thoughts?

I picked my car up on Wednesday. I've not tried my N4 with it via Bluetooth Audio yet as I have a 32gb USB Drive doing nothing so I've just put that in there.
The only issue I'm having is getting Text Messaging working with my N4. It just says that the Nexus 4 does not support this feature. I've looked around and found people mentioning the MAP Profile setting but I can't find it anywhere. My only guess is that this setting doesn't exist on the UK Version which is built in to the new Fiesta.
People from the UK can't even register on Syncmyride.com

Using Services (Sending Location)
Is anyone else here having an issue with Ford Sync Services & their Nexus 4s? Specifically, I have a Ford Fiesta with the latest Sync SW, and every time I use Services (for instance to get directions or to find out traffic), it says it can't find my location.
Just want to rule out that it's the phone that's the problem- so has anyone successfully done this with their N4s?
Thanks!

All I've found is that the Nexus 4 lacksthe BT MAP Profile which is required by Sync to use Text Messaging. Samsung devices on the other hand have the BT MAP Profile, so my girlfriends phone works fine with it.
CM 10.1 supposedly has the profile but it's broken. I've been checking the nightlies but no one has fixed it yet. If I knew what I was doing I'd have a go at porting the profile over from a samsung device myself.

I also have been trying CM 10.1 to get MAP working so I can access text messages on MyFord Touch in my Focus. Just updated to CM 10.1 RC2 and it still isn't working for me.

I just want to know whose hare-brained idea it was to eliminate UMS from Android in the first place.
Both my N4 and my wife's SGS3 (i747) get stuck at "INDEXING" forever when plugging into Sync in our 2012 Fusion. She actually switched back to her HTC Vivid because of it.
Here's to hoping 10.1 final will restore UMS functionality.

I had the "indexing forever problem" when I first tried USB with nexus 4.I noticed that a couple minutes in the phone would show "media.process has stopped". What I did was clear the USB mass storage cache. Settings>apps>all>media storage>clear cache. Then no problems. Sync finished indexing in a minute and media voice control works fine. I use syncmyitunes to add music. When I first had problems I deleted all music on phone and added only one song to the music folder to index the first time. This might help also. Now after all this, sync occasionally states it has detected a new device and indexes again. Usually this is when I forget to plug in the phone BEFORE starting the car. Hope this helps someone.

[Q] Bluetooth on Nexus 4 woes

Trying to connect the N4 to a car Bluetooth audio (2012 model car, relatively new, only 9 months old).
(1) I had a very hard time getting the two paired: lots of "connection failed" attempts until they finally connected.
(2) The phone does not send artist/track info which is surprising as I have an older LG phone running Android 2.3.4 and that sends all the info.
(3) Without any music being streamed to the car audio, if I make a phone call via the car bluetooth, when the call ends the music player on the N4 starts automatically. This is very annoying, not sure if it's a problem with the car implementation sending a "play" command at the end of the call or the N4 doing something weird. I tend to blame the N4 as two other phones, an iPhone and the older LG mentioned above do not do this.
(4) The car has a play/pause toggle that it can send to the bluetooth player. Pause works, the player on the N4 pauses, but then play doesn't work, I have to hit play on the device.
(5) After I use bluetooth on the N4, I find that sometimes the widget toggle can no longer turn bluetooth on/off until I reboot the phone.
(6) After I use bluetooth on the N4, the phone sometimes randomly reboots. Not sure if it's really related or just a coincidence. Given (5) above I suspect something is going on.
Anyone else having such a hard time with the bluetooth part? Potential hardware issue or simply buggy software that we can hope to get addressed at some point?

I have experienced the issue with track information not being sent. Also random changes in volume during playback. Seems there's still some work that needs to be done in 4.2 regarding blue tooth.

Is this an issue that can be addressed by flashing a custom ROM or perhaps using a different music player than stock or is there more to it, deep down in the bluetooth drivers and it would need a fix from Google in the form of new drivers?

Yeah I have had a few issues too. My track/artist/album names do not send where my S2 sends them. Also the headunit I have has buttons for shuffle and repeat and these do not show up at all (I assume because it detects they aren't supported). I haven't taken a call yet or tried turning BT off after streaming but I'll give it a shot and see.. My nexus 4 also randomly shuts down for no apparent reason sometimes (rarely atm). I think it's just 4.2.1 problems - I doubt a different music app will fix it (I tried one), custom ROM may work though..

My N4 is paired with an Alpine 135BT and it's worked very well so far. I initially had some trouble connecting but once they were paired I didn't have any additional connection issues. The N4 does automatically play as soon as it connects to the unit. I've got BeyondPod and Spotify installed and for whatever reason it always defaults to BeyondPod instead of Spotify even if I had BeyondPod closed and Spotify open. Not a big deal to me though.
Are you running the stock rom or a custom rom? I had my EVO LTE hooked up to the same head unit. It worked perfectly on the stock software but gave me all kinds of trouble when I started using custom roms. Otherwise, it could just be that the N4 and your particular head unit just don't play nicely together.

Trying to connect the N4 to a car Bluetooth audio (2012 model car, relatively new, only 9 months old).
(1) I had a very hard time getting the two paired: lots of "connection failed" attempts until they finally connected.
(2) The phone does not send artist/track info which is surprising as I have an older LG phone running Android 2.3.4 and that sends all the info.
(3) Without any music being streamed to the car audio, if I make a phone call via the car bluetooth, when the call ends the music player on the N4 starts automatically. This is very annoying, not sure if it's a problem with the car implementation sending a "play" command at the end of the call or the N4 doing something weird. I tend to blame the N4 as two other phones, an iPhone and the older LG mentioned above do not do this.
(4) The car has a play/pause toggle that it can send to the bluetooth player. Pause works, the player on the N4 pauses, but then play doesn't work, I have to hit play on the device.
(5) After I use bluetooth on the N4, I find that sometimes the widget toggle can no longer turn bluetooth on/off until I reboot the phone.
(6) After I use bluetooth on the N4, the phone sometimes randomly reboots. Not sure if it's really related or just a coincidence. Given (5) above I suspect something is going on.
Anyone else having such a hard time with the bluetooth part? Potential hardware issue or simply buggy software that we can hope to get addressed at some point?

(1) Haven't had any connection issues so far on my vehicle or my wife's.
(2) Currently stock Android uses AVCR v1.0 which only only allows you to control via Bluetooth (play, pause, etc) but not send track info. Other manufactures that customize Android (LG, Samsung, etc) will sometimes use v1.3 that supports track info. That's why your old phone did it.
You could install a custom Rom that has v1.3. I think cm10 does.
(3) Again, not happening on my two cars. The only time the music starts after a call is if it was playing before the call. I'm wondering if you have another music/podcast player that is taking over Bluetooth controls and causing problems. I use the stock player and Player Pro. If I don't disable the headset/BT controls in Player Pro I have control issues.
(4) I have the same issue. To get around this I cheat and push the track advance button on the radio to play the next track.
(5) This is an issue I've had on all of my previous android phones. I haven't noticed I my N4 because I never toggle off Bluetooth anymore.
(6) Not having this problem but maybe try solution in (3).

got the sony mw600 for bluetooth audio.. no id tags on display.. on every musicplayer (play music, poweramp, cm musicplayer..) the same.
dont know why, but today even the start/stop, forward and prev. buttons didnt work! the only thing i can use is volume control..
anyone an idea?

Any luck with this?
I want to buy one but couldn't find it in Sri Lanka so planning to order one via ebay & need to check if it works. Running cyanogen mod 10, heard that the bluetooth stack was updated on CM which supports most of the features since stock rom only has older stack version which can have issues!

I also have the track name issue. This is a massive let down. I like to just get in my car and flip through tracks with my phone in my pocket. My iPhone did this, my s3 did this. Why not the nexus 4? Come on Google. Sort it out

my impression is that almost nothing involving Bluetooth functions as it should currently on the N4. I can't even get a mouse to work. what a shambles! it's not as if BT is some new technology. this all better get sorted out in 4.2.2.

If I'm not mistaken Google moved to a new Broadcom b/t stack. Yeah, good move! And I agree, b/t has been around for like what at least 10 years now? You'd think that getting track info should be a given by now. I have a crappy old LG phone running Gingerbread and it has no issues at all.

Bluetooth
When I got the N4, I connected my helmet headset to it and everything seems to work fine. My headset supports ad2p music and phone. Both connected and both worked, including play controls. Not sure about the audio quality, I didn't test it long enough After I flashed Jellybro (CM 10.1 Kang) Music connects, but phone goes on a connect/disconnect loop. Audio needs further testing, can't tell if the left side is off because of the bluetooth or not. Controls work most of the time, every now and again playback will decide to pause itself and sometimes the play command doesn't work. Haven't had a chance to flash stock CM 10.1 nightly yet either.

Play/Pause Works Inconsistently
Has anyone had this issue?
I am on stock 4.2.2, I connect with my car stereo no problems. I use to be able to just hit play/pause on my car stereo and it would just play music from Google Music. Now, sometimes when I hit the play/pause button on my stereo, it won't play. I have to manually hit play from my phone. After initially doing that, then I can hit play/pause and the control is there. I haven't had the problem since I got my phone on Nov 14th, this issue just started to happen. I notice this after installing Light Manager, but I have uninstalled it and still the issue is there. It is inconsistent, but the issue is more often than not.
Thanks in advance for your input.
Just reiterating, stock Android does not show artist/track info, it is not in the protocol, but you can skip tracks or go back to previous tracks. If it is important to you, you should root and get a custom ROM, not sure which ones for N4 has it though, been too happy with stock to root.

About time, Google:

Is anyone else having problems wit Bluetooth audio streaming in car? My music sounds like it's speed up a tiny bit. Kinda like chipmunks voices. Is this a ROM issue?
