[Q] have to set up bluetooth pairing every time with car radio? - Nexus 4 Q&A, Help & Troubleshooting

Im running m-10.1.3 on my nexus 4
I have to set up Bluetooth pairing every time I get in my car or I turn off Bluetooth.
I use to just be able to turn my Bluetooth and it would just connect but it stoped working after I reflashed to fix a other problems.
My radio can only hold about 5 Bluetooth profiles and it fills up and I have to delete them. After it connections it works fine.

Bluetooth not connectig automatically to the car kit

Hi guys,
I have a very strange problem with my beloved note. After I get in the car and drive off I remember that I have to turn bluetooth on so it can connect to the hands free system. The thing is that it doesn't connect automatically, I have to go into the settings and tap the BT name in order to connect it. If on the other hand if I have BT already enabled on the phone before starting the car, it conmects automatically. With the first version of GB the Note had in November I didn't have this issue, but after the first update it started not to work. Now I am on official unrooted ICS 4.0.3. Never had this problem with any other phone.... Any help would be highly appreciated.
Thanks.

You can try Automatic Bluetooth Toggle PRO (I think there is trial version on Google Play). I don't know if it will help you. If not then I'm sorry you will probably have to go back to GB. I'm still on GB as I was also having issues with bluetooth on stock ICS (CM9-based ROMs worked well though).
Thanks a lot. GB had the same annoying problem though :-(... so it's not that....

Hi,
Did you allow the pairing automatically between the devices?
When you pair at installation, it isn't permanently (= automatic) yet. When you get in your car and pair for a second time, normally your phone asks you if you allow your hands free system to access your phone; at that moment you have to tick "don't ask me again" and "yes" for automatic paring.
You might want to disassociate the two and try a new setup (pairing).
To disassociate, stop the system in your car (that cuts the BT connection between the two), disassociate on the phone (push and hold your hands free system in the BT section of the phone and chose disassociate), reboot your phone (so it forgets your cars BT system) and start pairing all over again.
I would provoke the second connection so you get the "automatic" question to make it work.
Good luck :good:
I have the same problem with the original ICS rom.
Flashing a custom ICS rom fixes this problem.
I tried kingdroid (worked ok)
I tried Cyanogen (phone ok, no media audio over BT but connection OK).
I had a similar problem after upgrade with stock ICS through software update. I couldn't pair Note with Mercedes bluetooth. Galaxy Note recognized Mercedes BT & vice versa, but connection was impossible. I read every forum on internet but no help. Everybody was blaming Samsung and ICS. Some suggested resseting Note to factory default, others downloading bluetooth app etc.
Until...I finally figured out that something was confusing my car's BT, so I resseted car system, and the problem was solved.

These is a twist with "old" BT systems and ICS: Old BT systems want you to insert a pin code, ICS wants you to to confirm a code that the BT system sends and that ICS shows on the screen.
It's obvious that that ICS on an old system can be a hassle.
A work around is to put the car in discover mode (so it shows the pin code) and then send a contact (or a picture) from the phone to the car system. As the car replies, your phone will show the possibility to insert the PIN Code.
After that your system should work.
At second connection make the pairing automatic (as I described above) and you're happy.
(This is not my discovery, I found this solution on the SE XPeria Ray forum as I had problems with my wifes phone )
Thaks a lot. I will try as soon as I get the chance and will let you guys know.

So with the workaround mentioned above - it doesn't work. When turning on bt on the phone it won't automatically connect to the car.

Try A2DP Volume on the market.
I have the same problem as you. I used a leaked ics rom on my galaxy s2 and also had the same problem we now have on our ics galaxy notes. My car's head unit is a 3 year old eclipse cd5030. For the last month ive just been manually pairing it every time. PITA. Ill try the workaround suggested earlier in this thread and let you know. Otherwise i think cyanogen mod rom may work.

I had similar issues with Parrot 9200 kit in my car. Paired automatically under GB but on stock ICS wouldn't pair unprompted. Sometimes it would but only after minutes.
I'm on Paranoid Android 0.4 now which is CM9 based. It's better but often still slow to pair unprompted. Main improvement for me is that the phone doesn't carry on playing music through its own speaker, like it did on stock ICS, when I turn off the engine.
There is an app on the market called "Auto Connect 2.0", but it is only available for ICS and above Android versions

i have same problem with my note, but with my Galaxy S1 works fine, when i upgrade the android to 4.0.4 solves the problem.

Q: Default bluetooth profiles

Previously i had an S3 that would automatically connect call audio and media to my 11 wrx. This worked perfectly as i listen to pandora on my way to and from work.
My new s4 only automatically connects the call audio and not media. I have to manually connect the media everytjme the car turns on.
Is there any way to change these defaults?

I'm having similar issues. I cannot change the default profiles and the phone doesn't autoconnect at all. If I turn off the bluetooth and turn it on, the media will connect.
On my Galaxy Nexus I had no issues, both profile boxes were checked and the phone would connect to hpne and media as soon as I turned the car on.
This is frustrating because one of the primary uses for my phone is music in the car and I really love the way the bluetooth works with calls in the car.
^so any ideas on a fix?

I have the opposite - connects to Media but not to phone
I also have a 2011 Subaru WRX and have difficulty with my SGS4 auto connecting. As stated by the original post, upon turning on my car, my phone connects the "phone" portion and not the "media." Any help would be appreciated as this is quite annoying. I was previously with an HTC DNA...which auto connected with ease in both aspects, yet didn't display song data. Now, my situation is reversed in a sense...haha....

Maybe the issue is actually with the car. I have a 2013 Subaru Legacy
I'm sure your setup is the same as mine but thought I'd share. I never touched the settings when I first paired the phone to my '12 civic.

After manually connecting by hitting both those checkboxes repeatedly, it will eventually look like that.

S4 bluetooth reconnection issue

Friend of mine has a new s4, and is having some trouble with his phone and auto reconnecting, he has to manually select media, but it does automatically pick up the phone part of the connection.
It is a 2011 subaru impreza for what it's worth, with the standard factory head unit.
I have the same car, and a note 2, and mine will reconnect but I lose the steering wheel control unless I disconnect and reconnect to the car. I am not sure if that information is helpful at all, but maybe it will identify the issue. In both cases an iphone 4 worked fine, and in my car an xperia ion as well, so we can only assume it isn't all on the car.
I apologize if I missed anyone covering this before, I searched and didn't find anything relevant.
Thanks in advance!

Same here. S4 reestablishes call audio with Avantree Cara, but not media audio. Have to toggle bluetooth to reconnect.
Reconnection works fine with Bluebuds X however. They'll hopefully patch that in an update.

Bluetooth won't reconnect?

This issue only seems to occur with my car, a 2013 WRX. I connected fine and typically every subsequent time I get in the car and start up as long as Bluetooth is on my phone will automatically connect. This was the case with my Gnex and the moto x. The G2 connects the first time fine but then the next time it won't connect, almost as if it's a different phone. The cars Bluetooth is pretty basic so it will only save one device so I end up having to delete it and start over.
The phone auto connects to other devices like my obd dongle and my outdoor speakers just not the car. And it worked in the car with other phones so I'm stumped. Anyone have any ideas?

I have the same problem with my 2011 WRX. G2 will connect fine the first time but every time after that i need to manually connect and that will only work every 3rd time.Very annoying.

Have you tried letting it go for a while? I noticed its very slow to reconnect in my car (Infiniti), but it does eventually reconnect.
I havent tested it yet, but I noticed if the screen is on during reconnect, I get a message box saying the car is accessing the phonebook....Im wondering if it pulling the phonebook every time is slowing down the reconnection process.
Found a Solution
Found a solution, want to thank 2011_ST over at forums.androidcentral.com for pointing me in the right direction. The WRX head unit is very weird. The paired devices it shows you when you use the buttons to see all devices is different from the paired devices it tells you when you use the voice navigation to pair and delete devices. I had to use the voice navigation to delete my last 2 phones, than pair the LG G2. Problem solved, phone connects in the first 10 seconds after car starts.
Could you elaborate a little on where you see the different devices?
Since this I've actually gotten a new G2 due to issues with calls not coming through with the first. Still having the same issue. I cleared everything out today and started navigation and tried connecting after that started but I don't see a difference. After turning the car off and back on it doesn't reconnect. It saves the car in my BT settings and if I go in and uncheck and recheck phone and media audio it then reconnects without repairing but it will not auto connect.
For others the WRX Bluetooth I'd very basic, no contacts syncing or anything like that so I know this isn't the issue.
Thanks

Bluetooth Connects - Disconnects Repeatedly - Car Bluetooth Audio

I have been using LG G2 for more than 4 months.
I always connect my phone to my car's bluetooth.
However, I have been having problems with Bluetooth for all versions of LG G2
I have used Stock 4.2.2 and 4.4.2
I have tried several different roms. Rayglobe, Flex, CloudyFa etc.
My problem is when I connect my phone to my car's audio.
It connects/disconnects repeatedly with a click sound, which makes you think that speakers will explode.
It stops after a long time but it is really annoying.
My only success what I had used 4.4.2 AOSP and it works without problem. But I am a big fan of Stock.
I have read a lot of threads regarding this issue and I am happy that I am not alone or hallucinating.
In all these thread people say that I have to disable bluetooth power save and everything will be okay but it is not, as people reported.
Looking forward to having a solution with this thread.

tried to go to hidden settings and enable A2DP Mode Sink?
dunno what it does, but might work. go to hidden settings via dialiing 3845#*802# (depending on model)
find BT_TEST > enable a2dp mode
I changed setting as you recommended.
I will check when I get back to my car let you know .

Are you able to test the Bluetooth connections with another LG G2? I am having a similar problem, and I found out the demo unit has no problems whatsoever. T-Mobile is sending me a replacement phone. Please see my link for more info http://forum.xda-developers.com/showthread.php?t=2749891
