I have a Kenwood KDC-MP642U car audio system with Bluetooth capabilities and I have my HTC Touch Pro 2 [t-mobile] successfully paired and working great with 1 annoying exception.
As soon as the units connect to each other the contacts / phone book start downloading from the phone to the Kenwood system which is fine, however..... after EVERY call the contacts download fully again making the phone barely usable [slow] until the full phone book is downloaded. [90 secs for 150 contacts]
There is no setting on the Kenwood unit to not allow automatic download... if the phone supports it.... it will download. I was told by sales rep that his Kenwood did that as well and just to live with it ? ? ? ? ? ?
I have tried to find the appropriate registry setting on TP2 to deny auto PBAP access and download and cant find any help on this...... any help would be greatly appreciated.
I have the same setup, and noticed it on my prior phone as well (Motorola KRZR K1). I believe that the phone is updating the "recent calls" list on the headunit. I know for me the second download is MUCH faster than the first.
I haven't seen any information about preventing the update download.
this should do the trick:

Question: does it show up as one of the profiles under the bluetooth paired devices list?
I just picked up a my new Note II yesterday, have done nothing to it except install the latest update. This thing is STOCK. My issue is with the Bluetooth connection in my car. I have a 2009 BMW with IDrive which has the Bluetooth integration built in to it. My HD-2, Sensation, GNexus, original Note all connect very nicely to the Bluetooth but my Note II is struggling. I paired it yesterday on the way home from the AT&T store and it worked fine. When prompted to allow the phone book during my initial pairing I checked the box "Don't ask me again" and clicked "Yes", same thing I've done on all my other phones. This morning however it would continue to drop out. It would connect for 15-20 seconds and I would see the little icon that tells me the phone is transferring the contacts then it would simply drop out. 15 -20 seconds later it would recycle and do the same thing again. When I was looking at the contact list on my car's screen it was showing AT&T address book which I do not use (it was just one contact, "something" AT&T) and in fact froze everything AT&T I could through the settings menu . I then deleted the phone from the car's menu and repaired it to the IDrive but this time I said no to allow the phone book. It was not dropping the connection but was constantly trying to obtain the contact data based on the icon on my car's screen. Then all of sudden I received an alert stating an "SOS Call System Failure", my car has a built in SOS function like Onstar....I deleted the phone again and the warning in my IDrive regarding the SOS failure went away.
I searched the BMW forums and found other people with this problem but these were from the '07-'08 time frames and that fix was software to the car. The software in my car is updated and so is the B/T profiles I also found a thread here regarding a similar issue but there was no resolution. Has anyone else had this experience with the Note II? I know enough to get myself in trouble but not enough to figure this out. Is it possible the Bluetooth in the phone only wants to transmit the AT&T address book vs. the Google contacts?? I guess it could be the software in the car but my other Note, whether running stock or CM 9/10 ran flawlessly with regards to the Bluetooth.
Weird, yesterday it's fine and today not so much. Did the last software update have anything in it that affected the B/T?
Any insight would be much appreciated, thanks.
UPDATE-appears my car cannot handle a Bluetooth profile of 4.0. All my previous phones were no higher than 3.0. Hoping BMW will offer a software update at some point but in the mean time if I go with a custom ROM will they probably keep the Bluetooth profile the same as stock or is that something they change??
I updated to Lollipop and now my Bluetooth will not stay connected in my car. I'll drop bluetooth after about 15 minutes on the deck, but my phone will say it's still connected. I have toggled bluetooth and it will reconnect, but no audio. I have to restart my phone to get audio back for another 15 minutes. I've repaired the phone to the car, done a factory reset, cleared the cache. I'm at a lose, does anyone have any words of advice?

I have the same problem after updating to lollipop. With kitkat I had never an issue. Have been searching for solutions during last couple of months. We only can wait until the next update I think. Or revert back to Kitkat. You should make your car audio as trusted bluetooth device. But that didn t help for me either, still had the same connection issues.
Before the update to Lollipop my device connected to my vehicle using Bluetooth (music, hand free calling/reads messages etc). And now after the update it STILL works the same.
Same here!
I have a Parrot MKi9100 and Note 4. Prior to the update it worked perfect, routing all audio from my phone through my truck. I updated to lollipop and only the calls would route (after clicking between speaker and bluetooth a few times). So then I updated the MKi to the latest version and now when it connects it thinks audio is constantly routing when nothing is! I had to delete the pairing so I can use my radio!
I sent a request to Parrot, but thought this would be an even better arena to escalate issues!
If you have power saving enabled. Switch it off and see if that helps. Just an idea.

I was having a problem with Bluetooth also. What I done was went to settings/Application Manager/All/go to Bluetooth and Bluetooth test/clear data then repair phone

I'm going to try this tomorrow.
I listen to music via bluetooth in both my truck and through my headphones.
On Kitkat, everything worked perfectly, but on Lollipop, the music "pops" or "skips" every so often. Completely random, but 3-6 times per song. It's really annoying.
Fix what resolved the issue for me (ATT Note 4 Lollipop)
1. Unpair both devices (remove the car from the phone; vice versa)
2. Make sure you turned off your bluetooth
3. Go to: Settings -> Applications -> Application Manager -> All
4. Clear Cache first then Clear Data: "Bluetooth", "Bluetooth Test"
5. Enable bluetooth & pair again with your car
6. IMMEDIATELY disconnect (you can do it from either way; car or bluetooth).. but keep the bluetooth turned ON
7. Download latest "Bluetooth File Transfer" application from Google Play
8. Open it and switch to the second tab ("bluetooth icon")
9. Select your car and do the following three things one by one (until they complete!!!): File Transfer Profile (FTP), Object Push Profile (OPP), Phone Book Access Profile (PBAP)
PLEASE NOTE: each of these steps may take 5-10 minutes and will FAIL for sure (a "STOP" sign will pop up in the application after it completed the action partially. Be patience and wait until that. If you did all three steps you can close the "Bluetooth File Transfer" app and move on Step 10.)
10. Go to Settings -> Security -> Trust agents -> Smart Lock (Google): ON
11. (you may need to leave and re-enter to Settings to see it) Smart Lock -> Trusted devices -> Bluetooth -> your car
Your phone should work again fine w/ the car. I've tried with my AT&T Note 4 after having the same issues.. 2 days perfect (even after few restarts). Also my friend followed these step on Verizon Note 4, also resolved the problem.

Worked great for me with the NOKIA CK-1W. Thank You!
I couldn't connect it with any device with lolipop system.
So it's a lolipop bug...
I tried this on my Samsung Note 4 and it appears I now have working Bluetooth Stack with my Lexus hands free. IMO when one deletes a Bluetooth profile any remnants in the Profile should be deleted. It seems silly one needs to go through these steps to repair the profile's Bluetooth stack. Hopefully Marshmellow will fix what is critically lacking in Lollipop.
Great post! Thanks for sharing this!
This issue with the BluetoothPbapService has been driving me nuts for the past months. An initial solution for me to force stop the BluetoothPbapService in the Bluetooth Share process under Settings -> Apps -> Running, but the service gets restarted each time you click on the Bluetooth option.
@jake_net's suggestion has inspired a workaround fix for me.
If you have a rooted Android, download this app from WangQi called Disable Service (from the PlayStore). Click on the System tab, select Bluetooth Share. Uncheck the BluetoothPbapService.
My Bluetooth connection with my car's handsfree has been flawless ever since.

I take it that you aren't from this forum, because we can't root our phones on Lollipop... and some of us are a little sore about it.

Sadly even after the 5.1.1 updated I'm still experiencing bluetooth issue's when my screen is off. When my screen is off, I experience skipping quite often, yet with my screen on bluetooth works fine.
I believe I've exhausted all means of troubleshooting this =/

I have left Nokia for similar reasons and got myself Samsung, now it is the time to leave Samsung behind and go for IPhone S6, my patience have ended.
Bluetooth Connection Dropping in Galaxy Note 4
I have the same problem after automatic updating my Note 4 from the original Android 5.0.2 to Android 5.1.1. This problem happens to my Headphone Sony MDR-10RBT that was working properly before, now after 1 to 3 minutes of playing music the BT connection just drops. My Bluetooth is working properly with the BT Keyboard with my car system BT for calls and audio, transfer files over BT, so the problem is selective......that is to say a huge BUG in the software. This Headphone is still working fine with my other Galaxy S5 with Android 5.0.1. I have tried every thing possible.... Soft Reset, Hard Reset, Cleaning Cache Partition, cleaning cache e data do BT app e BT test app.......... nothing solve the problem with the Sony Headphone. I have contacted Samsung and they told me to take my phone for the technical assistance?????? What for?! BT is functional. HUGE........ HUGE BUG. One other thing that stopped working in my Note 4 is the NFC???????? Shame on Samsung.... For me that is the end of it no more Samsung I have left Nokia for similar reasons, now head on to IPhone...

I dont know what to do when I get to the "Phone Book Access Profile (PBAP)" step. Can someone help?
When I select FTP or OPP, there is a distinct progress bar that tries to send data and fails.
When I select PBAP, I am presented with a bunch of files and folder but no option to transfer. I can long-press any file but really no way to upload them.
So what should I be doing here?
Thanks in advance.
Hey guys,
since I bought my bluetooth headphones (Wearhaus Arc), which are actually pretty cool, I have lots of troubles with them.
When I paired my phone (HTC One M8 running latest official stock unbranded Android 6.0) with the headphones the first time, everything was great.
While using them from day to day I was faced with connection issues. That means, that both my phone and headphones are on, but it takes (almost everytime) a couple of tries to connect them. Even if I tap in the saved devices on the headphone, the connect could not be established. Turning off and on the headphones and bluetooth on my phone was the only way to fix it.
If I finally had a connection, everything was fine. In a few very rare cases, the connection worked at the first go.
Some weeks ago, a new firmware for the headphones was released, so I wanted to install them. During the update process, the updater (Android app) said, that the verifcation failed and the firmware cound no be updated. Same behaviour with the Windows 10 app. Even with another phone it did not work. Seems like, something is wrong with the headphones.
So I contacted the support again (first time they gave me the advice to use the Windows 10 app to update firmware) and told me, that I have to return it for repair. The gave me a return label etc. and I sent it back.
After waiting a few weeks I finally got it back. With zest I turned them on, but the joy was marred, because my phone did not recognize them.
Before sending them back, I unpaired the headphones in order to start over with the new ones. Maybe this was the mistake...
I did some pairing testing with other phones (HTC Sensation, BlackBerry Q10, HTC HD2), which found the headphones immediately and worked fine. So my guess is, that only my M8 has a problem with them.
Pairing, unpairing and "repairing" (pairing again) between my M8 and the other mentioned phones worked well, so there cannot be an general bluetooth issue.
After doing a factory reset on my M8 I'm a step futher, because now the phone sees the headphones (somethimes), but it isn't able to establish a connection. In case I see it, I tap on the available devices, the phone tries to connect, but a second later I get the message: "unable to pair. Make sure your devices are on and discoverable, and then try pairing again". Rebooting the phone does not work. I also cleared the data and cache of the bluetooth share app and performed a network reset like described here: http://forum.xda-developers.com/htc-one-m8/help/htc-one-m8-bluetooth-wont-android-6-0-t3340279
My question to guys is, what can I do, to get the headphones to work?
Is it possible, that on the phone is still a piece of information left about the former connection, which refuses any new connection?
Is there a file on the phone, which stores the bluetooth connections? if yes, maybe deleting or editing the file could help?
Thank you in advance!

Hey there, I have trouble to pair Bluetooth of pixel 3 XL to my car.
Device info:
64GB pixel 3 XL black, unlock version, no root
Mazda CX-4 ver 2018, original Mazda Connect system, system ver. GW3M-41-018.1-M (this car is only available in China and no oversea edition, so I think this system is also customized.). Support Carplay but not Android auto.
Trouble description:
1. open pixel bluetooth to hold on
2. open Mazda connect bluetooth setting, ready to pair
3. pixel to choose new device, tap 'MAZDA' on screen
4. Mazda connect prompt a note with 6 digit pin and disappear less than 0.5 sec so that I cannot press screen/button to confirm
5. while pixel prompt a modal of same 6 digit pin, after tapping pair. This modal quit and prompt out 'cannot pair' info. After this note disappear, the last modal (seems like it comes first and hide in background) shows 'cannot pair due to wrong pin'
6. After double checking car manual, this device is an old ver bluetooth and its default pin have a limit of 4 digit.
So I cannot go out this bad loop after several trials.
Other phones works well like iphone 6s, huawei etc.
It's so embarrassed to use it in car. Now I use pixel to share wifi to my old ios connecting by carplay, but I still want to make the bluetooth function well and get rid of ios.
I have send feedback to Google but still no response. Is there anyway to fix it?

Thanks for your reply. I have tried to install android auto following this video (youtube tag:
ocOvY6Q7NNo, cannot post url) with MZD-AIO-TI_Setup_2.8.1, but failed... The head unit could read usd, but not auto run the script inside.
Have tried to connect when NFC off, still not work and I will inquiry car supplier later. Also heard someone in buyer group saying he cannot pair it to his BMW too.
It is really tricky and I will keep update this issue.

So sorry you are having issues. I have a Relatively new Kenwood Unit - I forget the model) when I first got the pixel Xl 3, initially I had problems getting it to be recognized - but once I figured out where the setitngs were for setting things up - it connected fine and now I don't have any issues - I can connect both wirelessly and via usb - wireless takes a bit longer - USB happens right away - I hope you can get things working for you....
