Hi,
Has anyone had issue trying to pair Nexus One (2.3.3) Stock to the Mercedes BT Command system?
For some reason, the car and phone can't find each other.
Let me know if there's a solution?
Cheers!

good luck!
I've always had this issue on MB bluetooth.
If you haven't, try this way:
On your command system go to phone, options or other options, "external autorisation".
When it's ready, search devices on your phone, you should find MB bluetooth
i have no problem to pair my nexus with my command ntg4.

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.
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.
I have my Nexus 7 installed in my car and I'm trying to get it to auto connect to my head unit. I've tried different apps, Tasker, and different settings and I believe the issue is because its a "media only" bluetooth device. Is there a way to add the "Phone Profile" like I have on my GNex to the Nexus 7?
I believe tablet talk has an option. I'll check and post A screenie

Thanks for the tip...I'll give it a shot. Hopefully this gives me the Phone profile in the Bluetooth settings.
Doesn't look like Tablet Talk will give the Nexus 7 the Phone Profile in the default bluetooth settings. Any other ideas?
Not really sure I don't have a Bluetooth headset. I just seen that in the settings.

You could try adding these services in the terminal:
Code:
% sdptool add HS
Headset service registered
% sdptool add HF
Handsfree service registered
% sdptool add HFAG
Handsfree AG service registered
You can also try to change the device class to "Phone, Smart phone":
Code:
% hciconfig hci0 class 0x5a020c
None of these changes will be visible in the GUI, but they might convince your car kit that it wants to auto connect. If it works, you can run these commands with Tasker and the Secure Settings plugin.

I'm having the same issue like the OP. I have android 4.2.1 and I can't find sdptool in system/bin/
I'm looking to do something similar here, and I know this topic has come up before. I want the N7 to act as a bluetooth "headset" for my N4 for a car install. It definitely lacks a phone profile.
Mega props if anyone figures out how to do that well.
YES!

Finally, others who know my pain! It is really frustrating because I am trying to have my Nexus 7 basically stand in for my head unit. Its pretty annoying if you have to set it up each and every time you get in and out of the car though. I'm on the verge of returning the JVC unless someone has made some headway.
Edit - tried sdptool from the command prompt and it did not work. Tried before and after rebooting. Working to find out more about hciconfig. This doesn't work right away from the command prompt. Time to thread crawl some more.
AW: Can the Nexus 7 be recognized as a bluetooth phone device?
sdptool and hciconfig are parts of the "old" Bluetooth stack Bluez. With Android 4.2 a new Bluetooth stack by Broadcom has been introduced, and I guess the old Bluez commands don't work anymore. And nobody confirmed that these commands were even helpful in this situation.
Count me among those who desparately want the N7 to auto connect to my car radio.

Hello everyone!! Just wanted to post this here to help anyone else who may had the same issue I had with trying to connect bluetooth devices ie OBDII devices.
So the only thing I did was open the bluetooth phone app, went to setting and changed the passkey to the same passkey as of the device. Soon as I did that and tried to connect to the OBD2 via Settings/Bluetooth, connected right up. Didn't need to install anything secondary.
Also: If someone could post a download link of the torque, and key mapping app for the device, I would appreciate it. Thanks.

You can install torque from the head unit. Open file manager and go to the oem folder

Thank you Sir!!!! Now I just need the others.
You could also try Turbo.
Just plug in your OBD2 adapter, launch the app and make driving smarter, safer and more efficient.

It's available for free on the play store.
I got this wonderful new unit and it works really well except a few things, mainly the Bluetooth sucks. I'm trying to get info from the maker of I can use bt for other things than the phone but I probably won't get the answer I want. There's a bt setting but no on or off switch and scanning doesn't do anything for me, it's completely frozen. Anyone know if there is a USB Bluetooth I can just plug in to work?
