I can't see any option anywhere in my SGS2 to set a BT paired device as "authorized". Every time I enter in my car I've to manually select the BT device and start manually the connection.
I searched in the forum but didn't find answers.
I also tried to look at the filesystem and I found auto_pairing.conf file in which there are a lot of BT manufacturer brands listed in sections like "black list", "white list", .... Is it possible I need to manually modify this file to include my BT manufacturer in the white list section? It sounds really strange!
Is there any other way?
I'd love to know that as well.

Update
I manually modified auto_pairing.conf file adding my car BT manufacturer without any success (I added it in white list with the name already mentioned in the file, so I think that's not a problem of brand name).
My SGS2 continue to ask me to manually select the device to connect to, even if only one BT device is available (car handsfree).
I have the same problem, which i didn't have with my Nexus One running Cynogenmod ROM. I keep my Bluetooth on all the time or most of the time and i would like (like i had in nexus one) when i turn on my car (with Sony MEX-BT3700U car stereo with Bluetooth) that the phone auto-connects with the stereo in a minute or less (or with my plantronics headset when i turn it on), but no, every time i have to go into bluetooth settings and connect on the paired device and then it's connected.
I heard about few application that could help but it would be nice to have it as native function on the phone. I haven't tried these apps yet but if anyone want's to try they can be downloaded from the market, firs is free, the second is not.

If anyone can help it would be greatly appreciated
I don't have this problem at all, on any ROM I've tried stock or not. Is your stereo also set up to auto-connect? And is it your phone or your stereo that's refusing the auto connection?

Stereo doesn't have any options, same as Plantronics headset (only ON or OFF), that means that with my old nexus one running CM (or Nokia n95 8GB) when the bluetooth is switched ON and i come near stereo or headset they connect automatically in about 30 seconds max, with my SGS 2 that doesn't happen, i tried everything but it wont auto-connect until i initiate the connection from phone manually.
I have to resolve this because it's killing me !

I wonder if that's the issue; IIRC it's my stereo that I've told to connect automatically rather than my phone. I'll verify on my commute home today.
Mine auto connects to my JVC car head unit, but doesn't to my Belkin Tunestage. No idea why. As it happens, this suits me but it'd be nice to be able to control it.
And the commute begins. The auto connection is an option on my JVC deck, no such option on the phone.

The stereo is recognized same as Plantronics and that is as a head set, but it doesn't want to automatically connect to either of them, every time i have to initiate the connection. There is one way to connect it (partially automatically ) but that's not the solution - i have to turn on the bluetooth on my phone before starting my car, then when phone is in searching mode if the car is started (stereo turned on) then it will connect automatically, if the search mode (that is active for a short time after turning the bluetooth) ended before i start the car (for instance if i keep my bluetooth on all the time on my phone) then it wont connect automatically.
Am i any clearer about my problem ?
I hear what you're saying but it appears that auto connection is initiated by my stereo. If I turn auto connect off on my stereo there is no connection until I tell my phone to connect. I don't see anything on the gsii settings to have the phone auto initiate the connection. I have a recent JVC deck fwiw.

I will check one more time is there any bluetooth settings on my car stereo, but i'm 90% sure that it doesn't have, because this is the first phone that doesn't connect automatically.
I have had similar issues with mine, it will pair with my Kenwood DNX520VBT but wont auto connect.
however i now have a workaround
Turn bluetooth on your GS2 first, then turn on you Radio. once my Radio boots up it initiates the connection and auto connect works.
if i turn on the bluetooth on my GS2 after my radio it never works.
ive got a sony bt3700 stereo, it connected perfectly with my samsung wave, i just upgraded to a galaxy s and i have to do it manually every time so its not the stereo.
Same thing happened to me, old nexus one with CM7 is connecting ok but i have to connect SGS2 manually or make sure that my bluetooth is ON on my phone before i start the car.
I may have the answer......
Hi,
I have a sort of work around.
My Pioneer head unit refuses to auto connect to my SGS2 and I have to do it manually (I connect from the radio in 4 clicks but thats not the point). This was driving me nuts as previous handsets I owned connected within 5 seconds of being in the car.
I then discovered ROMS and went for the Criskelo ROM and it put me on Android Version 2.3.6 (Not sure if that made a difference or its actually the ROM).
Now with that sorted I found that I have an extra function in my bluetooth settings. When I make the device visible I can then choose the visible time-out length. If I set this to NEVER then I have no problems connecting to the headunit everytime I get in my car.
The only problem I have with this is that I pop my phone into Airplane Mode each night and because that disables the bluetooth it loses the time-out setting so I have to put the time-out back to never each morning.
With setting the time-out to never I'm not sure what battery drain is like because I'm constantly on my phone and my battery depletes rapidly anyway but it seems like a fix for now.
I hope this makes sense and helps people out until a proper fix becomes available.
Cheers,

Hi All,
Sorry for bumping an old-ish thread, but it seemed the most appropriate thread, and better than creating a new one of the same topic!
This is what I believe to be true:
*IF* Bluetooth is enabled on the GS2 (and the phone has previously been paired with the car headunit) then when the car is turned on, it will auto-connect to the GS2
*IF* Bluetooth is NOT enabled on the GS2 (and the phone has previously been paired with the car headunit) then when the car is turned on, it will NOT connect to the GS2 (understandably!).
*IF* the phone has previously been paired with the car headunit, and the bluetooth on the GS2 is enabled *AFTER* the car has been started, it does NOT Auto-Connect.
From this, I assume that when the car is powered on, it searches for previously paired handsets in order of most recently connected first. If it finds one, then it WILL connect.
Now:
If I leave Bluetooth enabled on my phone, the battery is significantly depleted my mid-afternoon.
I've started using an app which uses the "rough location" (not GPS) to monitor where the phone is located. If it deemed to have moved in X period of time, then it enables bluetooth.
This is great, and works a charm ... BUT it does mean that bluetooth stack on the GS2 is enabled AFTER the car has been moving for a period of time, and thus does NOT auto-connect.
What I've been searching for is:
"When BT stack is enabled on GS2, can it look for previously paired devices and initiate the connection itself?" (Rather than the car connecting to it?) Is there a script or app to do this?
Hi WTFH,
I think it might be more headunit specific. I always have my bluetooth on but it wont connect automatically to my headunit unless I have it set to constantly discoverable (on the handset).
I also use a power saving program called Green Power Premium which will cut bluetooth/data/wifi after a certain amount of time when the phone is in a sleep state. Its great fro saving power as my phone isnt constantly looking for a wifi signal (I don';t use it to control my bluetooth though as I need it on for my car).
Hey DJ_sploits,
Thanks for that ... Yes, I understand that some headsets do not auto-connect to the GS2 if the phone is NOT visible.
But what does seem to be constant is that the GS2 will not auto-connect to any of the headsets if the bluetooth stack on the GS2 is enabled AFTER the headset has come online and available.
One workaround I'm thinking of is:
Enabling a profile which says "When connected to a power source (I'll have to use the power adaptor) then enable bluetooth". Connecting my phone to the power first before starting the car should enable the BT stack before the headset tries to connect.
In fact I could extend this to say "Only enable bluetooth when using power adaptor, and not connected to wifi".
It's still a pain to do this though, as I tend to just jump into the car and don't want to faff about with connecting this and that.
The only other work around I use is to set the visiblity to constant (depending on what android software version you are on). My headunit always picks the phone up if I have it setup like this. the only thing with that is it will eat the battery even more (which is annoying considering there are other phones out there that constantly have their bluetooth on and you never see the battery getting hammered).
The only flaw I can see in your method is the fact you need a power source to knock on the bluetooth. Great for powersaving but it would then mean you would have to remember to connect it to a car charger everytime you got in the car (not too bad if you have it constantly plugged in to the cigarette lighter) and as you set this can be a bit of a faff.
The only way I can see in sorting this is using a power saving app but having your visibilty constantly on for the bluetooth and then we just hope it doesnt eat the battery too much (not to bad for me as I have a charger at work but could be a pain for others). The only problem with this (apart from the battery issue) is that if you knock the bluetooth off or knock the phone to airplane mode (as I do at nights) then when you knock the bluetooth back on it forgets that you want it to be constantly visible so you have to go through the settings and check the box
So I drive a 2010 Nissan Sentra, which has a built in iPod/iPhone hookup to control audio through the steering wheel or stereo (has access to artists/albums/playlists/etc). Now, up until a couple days ago I kept an old iPod filled with music in my center console where the hookup cable was located and was able to play music fine. That iPod has been stolen from my car... wonderful.
So my question is this: Is the Droid Razr capable of playing audio through the micro usb port? I know If so, would something like this http://www.ebay.com/itm/Micro-USB-m...751409?pt=PDA_Accessories&hash=item2a223873b1 work to play music through my car via google play? My options are that or Aux (which means i cant safely change music while driving), seeing as my car does not support Bluetooth audio, and the iPod cable => car is proprietary, not USB. Would another option possibly be an iPod connector ==> Bluetooth, and connect my phone that way?
My Razr is Verizon running stock CM10.
I will try to keep this short.
First- usb ports in car audio will have different levels of support for devices. I usually work with aftermarket equipment as my cars are old, so this MIGHT not apply in your case. In a nutshell, if you plug in via usb, AND the car supports this, its going to try to approach the razr as if it were a usb flash drive, and attempt to read the music FILES you have in there. Two points here- this is NOT a direct audio stream, and thus will not send through audio from any apps on the phone, ie pandora or nav. Your steering controls will work, if this mode happens to work. Also, some stereos support this mode, but have the limitation of only seeing the first drive available and ignoring the others. The razr has two storages and it seems to present the internal first. Because of this the radio sometimes cant see your files.
In my case, my radio would only read the "wrong" partition, where none of my files were. I would up buying a cheap flash drive and leaving that in the radio, while my phone is docked on the windshield with an aux line running in so i can get pandora, etc.
Bluetooth is an option for me, but sounded terrible so i only use it for phone functions.

seeing as my car uses a proprietary port for iPod-in, not a USB port, your suggestions are not possible, but def appreciated. I wonder if the iPod 30pin ==> micro-USB will translate to reading the files off the phone as a mass storage in the manor you are suggesting. Thats going to require putting out some $ and downloading my files from the cloud, and then moving stuff around if its reading from the wrong location in the same way it was with your phone.
I've been researching this for a few days now and I am disappointed that I can not find any way to get my Note 2 to allow music playback over USB through the car's USB port. I am trying to hook it up to a Mitsubishi MMCS system.
I know that Samsung has removed UMS on their new phones and that's what most car stereos are used for. I downloaded SGS3 Easy UMS and it seems to work fine (except for the phone appearing as read-only cd drive when I plug it into my computer), and I can access every folder on the device in this mode - at least on the computer. When I plug it into the USB in the car, it starts charging, but the USB/ipod mode on the NAV says "No connection". And yes, it works fine if I hook it up to my old iphone.
My phone has been rooted and I even unlocked it and installed this custom rom on the device, but I still am at a no go. Unfortunately, using my phone as a media device for my car stereo on my long trips to work is one of the main functions I use my phone for. Right now I am stuck using bluetooth which has horrible quality and doesn't offer near the same amount of features on the stereo as USB does.
Does anyone have any ideas or am I simply hosed?
Hi. I have a USB port on my car which can be used to play mp3 files of aauSB flash memory through the in car stereo system. The problem is, I needed to quickly transfer some music from my phone (Xperia Z3) to the flash memory, so I used a USB OTG cable to get it of my phone and into the USB storage. Only problem is, immediately after I plugged in the USB memory, the car did not recognise it, saying it is unsupported. I stopped the engine, waited some 10-15 minutes (so I made sure the car shut down it's computer), them tried again and did not succeed. So this leaves me wondering what could have gone wrong. I know I can simply format the memory and refill it again with the data, but I am really interested in what happened: what does actually Android do to such as memory when connected to the handset? I have to mention that the cults on the memory look fine, both on my Windows PC, and on my phone. Also, of useful, I don't know what OS the car uses, but it is a 2013 BMW 3 Series. Thanks for any help.
I just bought a V521. I primarily want to use it in my car as a navigation unit.
1. To conserve battery, I plan to set it to turn off if it detects the cable is unplugged/no power (perhaps after a delay). Is there a way to have it turn on if it detects the cable is plugged in/power to cable?
2. Any tips on how to get it to startup faster? I'd prefer not to have a long wait everytime I start my car. Perhaps I remove or disable something
I'd appreciate any general tips as well
