Problem with making calls on car headunit - Nexus 4 Q&A, Help & Troubleshooting

Hey guys, I have an issue with my N4, regarding a car head unit, a Kenwood 4028BT. I can successfully connect the phone to it, and can receive phone call, and can control the call from the head unit. My problem is when I attempt to make a call, it makes the call on my phone, with the icon shown that is connected to a bluetooth earpiece, but no sound, either on my end, or the receiving end.
The headunit is fine btw, since I attempted to connect my gf's Xperia U, and can successfully make and receive calls, so the problem is surely with the N4. I saw online some threads saying that this is more a bug that is introduced since 5.0, so maybe not specifically with the N4, but still, maybe you guys had a similar issue, and found a solution?
Thanks in advance!

any ideas?

BMW BT handsfree broken

Hi,
Received my HD2 a few days ago and had no problem making calls with the OEM BT Handsfree of my 2009 3-serie BMW.
Until I discovered that I coudn't use it to receive calls !
The HF picks-up the call OK via the iDrive or steering wheel button, but audio is dead. Both parties can's hear anything.
It's actually possible to make it work two ways: first, by answering the call via the phone button instead of the car's one, or second, by answering with the steering button or iDrive having no audio first, then by going to the phone and disconnect and reconnect the Handsfree via the phone menu and at that point the audio comes back working ok.
It is a real disapointment as my previous Diamond touch was working flawlessly in the same car.
Not to mention that it pretty useless like that because of the danger implied by trying to rush to the phone in a deap pocket or in the arm's rest compartment to push the answer key.
I hope HTC will fix that soon as it pretty useless for guys like me, working 2h of their day in the car. It seems they changed from a MS BT stack to a Widcomm, loosing compatibility in the process...
Anyone experienced the same yet ?
Yves.
Yes, i have similar problem with my BWM X5 Bluetooth.
When i am on call and same time put they key can't hear nothing from phone and from hands free. Same is if go out from the car and have call in same moment.
With my previos phone HTC HD - all working great.
Ok, thanks for the reply.
I really think it is due to the change of BT stack.
BTW, did you file a ticket to HTC support ?
I did yesterday, obviously no answer yet but could you do it too ?
The more we are, better are the chances that they do something for the next rom.
Hello,
here is my issue with the BT connection: I have a Pioneer F900BT unit in my car. With my previous Nokia E66 everything worked just fine.
Now, when connecting with HD2, conection works ok, phonebook is downloaded ok, BUT: when there is a call, the music in the car is not silented automatically; what's worse, it seems the phone doesn't send any call identification to the headunit, since all the history (outgoing, incoming calls) is empty. So, I cannot redial or see who's calling me.
I did try the fix in the registry described earlier on this thread, but it doesn't help.
Any idea?
Thank you.
I have a 2008 3 series and have no problems at all, connected first time and has worked flawlessly ever since

Bluetooth carkit (audi factory)

I'm having much fun with my new Legend, and I love android 2.1!
Everythings goes smooth except the connection with my car.
I have a pretty new Audi TT from 2008, and with my old phone (t-mobile G1), I used it without a problem for over a year.
One month ago I bought the Legend, and bluetooth connection to the car seems to hang!, Even when I disable bluetooth, the phone becomes slow, and the bluetooth icoon keeps displaying in my notification erea.
One thing works, when I reset the phone, I can use the carkit for about 10 minutes, then it starts to disconnect. The adress book never syncs.
Can people please reply if they got their legend work properly with their bluetooth car kit.
Also when other people have problems, please reply here!
Thnx
I have a mini cooper S with BT car kit.
The connection is good and all the contats are correctly transferred but sometimes the connection has been lost.
It seems it happens during the net switch (between UMTS/GSM).
Same problem here. Kenwood DDX7029 with BT. 5 out of 10 times the phone won't connect when starting the car. Dis- and enabling BT does the trick.

This implies that if you disable data-roaming, it would work all the time?, I'm gonna try that out! Thanks for your reply!
Hi there. My first post in XDA
So cool that I found this thread because I have the exact same problem. I have an Audi A3 and the bluetooth connection is 9 out of 10 times lost during conversations and then the bluetooth icon just hangs until I boot the phone.
I'm gonna try to disable the data-roaming and see whether it works.
Still problem carkit/bluetooth Legend!!
Hi all,
I still/also experience problems with my Audi A4 carkit.
Also my colleague with a Opel Insignia experiencing the same problems.
I have to reset the bluetooth or reboot the phone te fix it
It is very annoying when you loose the bluetooth connection within a call.
I have already sent a message to HTC...and still waiting!
Switching off the data roaming or fix the UMTS/GSM settings doesn't help
Somebody a sollution?

Audi UHV 6654 problems
I have a BIG problem with this car kit connection...BIG means the device is useless till now.
I've paired the Legend with my A4 factory car kit and there are several problems:
1. No sounds come from the speakers (car speakers), still the michrophone is working fine. I had to put the phone on loudspeaker to hear something but of course this is not the normal way of using a car kit
2. There is no sound till the call is actually ongoing (the other party respond)...that means no ringing, busy tone, or whatsoever sound... I don't even know if the call is made if I'm not looking to the phone (and if it's entering power saving mode, I stare at a blank screen).
I don't have any problems of this kind using a Nokia phone and also they (especially point 2) are happening with all smartphones I've tried (WinMo or Android ones).
Is there any software (even a paid one) to outcome this?
Please don't tell me to "try" this and that, I don't want to spend money "trying" things...I would appreciate if someone had a similar problem and managed to solve it somehow.
P.S The phone is brand new (got it for 2 days by now) and it is not rooted.
P.S.2 The car kit is a "basic" one, don't have navigation, contacts downloading and all that stuff...It's a plain BT car kit, I would just like to be able to make and receive phone calls with it.
Seems like many have bad experience in making the legend and car kit work together.
As of yet I could only pair my legend with my blaupunkt audio system, but they have not yet connected each other successfully to make use of the bluetooth feature. I've had no problem at all using my audio set with my samsung galaxy spica's bluetooth. So it probably is not an android issue.
Is there anyone who didn't experience any such trouble with their legend and car audio system's bluetooth ?
To add some more details...
I search for BT devices, phone finds the Audi UHV car kit. Then I'm asked for the pairing password and I enter it, than I get that "connection sound" from the car speakers but the phone is still "connecting..." endlessly. The BT icon on the phone appears but is the standard one, no headset or car kit icon appears (does it have such an icon after all?)
From here...nothing special happens. When I make or receive a call only the phone is ringing, no sounds came from the car speakers. Only when the call is connected, then I have the bord computer showing "Call..." and the radio/CD is muted...and that's all. The conversation can be heard only into the phone not from car speakers as it was the case with the ringing tone before. When call ends, music resumes.

[Q] No Sound on Phone Calls after using Bluetooth

I've just encountered a strange and frustrating issue that began a couple of days ago on 7/12. I have a Galaxy S4 running 4.4.2 and a 2010 Nissan Altima. I've had my car for 4 years and have never had this issue with any of my phones until this past Saturday so I am convinced it is my phone that is the issue. The Bluetooth pairing will connect without issues (indicator on both phone and car screen indicates so) and I am able to make/receive a call with sound successfully for one time. If I a make or receive a second call, there will be no sound both on my end or the caller on the other end. I know the call connects since the call timer starts on both my phone and the car screen as well as on the caller's phone (tested out with my wife's phone while in the car). I will not even hear a ring tone, the call will just connect without sound. Even if I disconnect the Bluetooth connection, there will not be any sound coming from my handset and the caller on the other end cannot hear me when trying to perform a call. The issue can be temporarily fixed with a phone restart. After making one successful call on Bluetooth after a phone restart, the no sound issue will return. I'm not sure what to do at this point. I've re-done the phone pairing with my phone and car but the issue resurfaces. I see somebody posted a very similar issue on a different website on the same exact day I started getting the issue (Can only hear phone calls on Bluetooth) so I am wondering if we got some sort of app update that has started to interfere with Bluetooth connections. Any advice would be appreciated. Thanks.

Whatsapp/Skype calls not going through the Car OEMs bluetooth

Hi all,
I have a rather frustrating issue and I am not finding an answer. I drive an old 2007 Seat with an OEM bluetooth that is beautifully handled by the steering wheel and the dashboard.
I have a Note 3 SM-N9005 running Magma NX and I am very happy with it. When I connect the phone to the Bluetooth it only connects as Calls (Not media) and it handles regular calls perfectly. I do however have all my family overseas and rely a lot on whatsapp and skype calls to stay in touch and I drive a lot. When I receive a Whatsapp call, my own number shows in the dash and I can pick up the call and I can talk for a few 10 seconds and the the bluetooth link is lost. The call remains on but the link with the car is lost. I also tried it with a friends unrooted OEM Samsung J5 and the same thing happens.
HOWEVER! My wifes iphone SE does it all, calls, whatsapp and skype, and it is the very first time I am inclined to switch to an iphone, only because of that and I am not liking it.
Can anyone think of a reason why the iphone will handle voip call over the car's older oem BT whereas the android wont? Is there possibly a solution for it? (I am not changing my car or my car's stereo anytime soon)
Many thanks in advance for any pointers!

Something similar happened to me using my stereo's bluetooth feature, but my problem was that I wasn't able to link-pair them at all. I erased the stereo's history of connected and paired devices, I removed the stereo from my paired devices in my Note 3 also and re-paired them from the beginning. It works great after I did that, have you given it a try?

S10+ and Ford Sync v1 - phantom calls

I have a Ford Fiesta (2014 model, with Ford Sync 1; looks like this) and have had previous phones connected to this system with no issues previously. In fact the last phone connected before my S10+ was an S9+ and it worked great.
But... since I got the S10+ and connected it, I am having a weird issue with phantom calls. Specifically, when I get in the car, start the engine and the phone then finishes connecting over Bluetooth to the car it will make a phone call. However, the phone call is to "Unknown Number" and is completely silent. There is no ring tone, no answer on the other end, and the call does not show up in my Recent Calls screen in the dialler.
I have other Bluetooth devices connected/paired such as a smart watch, speakers and headphones, but the phone does not make this odd call when they connect - only when my car connects.
Appreciate this is a very specific problem with only my phone and the particular variant of Ford Sync I have in my car affected (and even then, only in my car!) but does anyone have any idea what might be going on here or how to stop it?
Thanks

I have the newer sync so I'm not sure but does Sync 1 have the system diagnostic that calls back to Ford? It almost sounds like that because when it called you didn't hear anything or see a number. Although I don't know why it would start with the S10. I guess you completely removed the phone from Sync and repaired it. This might be a good question for one of those Ford Owner Forums if you don't get anything here. I'll be pairing my S10 to my Sync 2 today or tomorrow so I hope I won't run into this.

It has an Emergency Caller function (i.e. if the system detects a crash/sudden impact it will call the emergency services) but I don't think this is what is happening here. I'm usually sitting still when this happens (start engine, systems come online and phone connects, while it's doing that I put my seatbelt on) and the call is completely silent - I thought my radio had lost signal the first few times I did it and then spotted the outgoing call to "Unknown Number" on the Sync screen.
