I have figured out a work-around for the auto pairing failure. I will give a step by step workaround how I did it. In my situation, I have a Mazda CX-5 and a Samsung Galaxy S3. But I am confident, that it will work with all Android 4.0.4 versions and other carkits, because the problem is most likely the same issue.

The reason why the phone won't auto pair, is because the phone does not give your carkit permission to download call history and other data. Even if you granted the phone this permission with the initial pairing.

If you have a carkit that supports multiple bluetooth profiles (multiple phones), like my Mazda CX-5 does, then you can also have your phonebook downloaded to your car. If your carkit supports multiple profiles, start with step 1. If yours doesn't, start with step 7. This guide is specifically for the Mazda CX-5, so some steps may be (slightly) different for your car model or make.

Here is the step by step guide:

1. Make sure you have no existing bluetooth pairs. Clear all pairs in your carkit and your phone.

2. Pair the phone with your carkit. You can see the randomly generated code on your phone and on the car display. Press ok to pair. (other carkits may need you to input "0000" of "1234", or maybe you have to input a code yourself)

3. Your phone will ask 2 questions about permissions. Check the box and allow. The phone will start to sync.

4. You carkit is done with syncing and it will ask you if you want to download your phonebook. Do this.

5. When its done copying, clear the Bluetooth pair on your phone (not on the Carkit!)

6. Give your phone a different Bluetooth name

7. In your carkit choose to pair a new phone (with the new name you just entered).

8. When the phone asks for permission for the carkit, check the box and choose cancel. Do this for both questions.

You don't have to copy your phonebook again (you can't anyway because you denied permission), but the phonebook that was downloaded earlier will still be available. Now the phone will pair automatically! With this trick you have your phonebook and automatic pairing.

I haven't seen what this does for media-audio streaming. I don't use that, but I can image that it doesn't work, because of the denied permissions.

There is another downside to this though (there always is, isn't it?). You cannot update your phonebook easily. If you want to update your phonebook, repeat the whole procedure.

I hope this will work for other people with different phones and cars too. At least this is a workaround until Google/Samsung comes with a fix. Please let us know if this works in your situation. To keep things structured, please use this format:

Car: Mazda CX-5
Phone: Samsung Galaxy S3
Works: Yes

how do you switch the bluetooth between headset to car inbuilt bluetooth automatically.

Scenario:

Phone already paired to Nokia headset and also Car inbuilt bluetooth.

Phone is connected to Nokia now. When I move in to the car it won't switch/connect to the car inbuilt bluetooth with out manually selecting it. Why android can't do this?

The Bluetooth issue with the Android 4.0.4 update for my AT&T Samsung Galaxy SII (SGH-I777) was its failure to pair with my car's audio system. This failure seems to be caused the the loss of the ability to enter 6-digit pairing codes using Android 4.0.4. After the upgrade I could not pair the phone with my 2010 Ford SYNC system, which generates a 6-digit random pairing code. Previous versions of Android distributed by AT&T for this phone did accept the 6-digit codes. A Ford posting gave a method for solving the problem using "reverse-pairing", outlined here:

.

In reverse pairing, the SYNC system generates a plain 0000 pairing code, which is accepted by the phone. After the reverse-pairing, everything worked fine, including the phonebook download, music streaming and all SYNC functions I have tried.

I have pasted in the Ford employee's posting in green below. I first removed all Bluetooth devices from the phone by unpairing them and powering the phone off and then on, and I then deleted all devices from the SYNC system. I did NOT do the Master Reset of the SYNC system that was suggested, though I suppose it would have done no harm.

Many Android users have experienced concerns after the recent 4.0 (Ice Cream sandwich) update.

Any time an update is made to your phone or SYNC, we recommend resetting the system and pairing your phone again. Below are instructions for how to perform a Master Reset as well as Reverse Pair your phone. Certain phones hold the best connection when paired this way so I highly suggest giving it a try. Instead of the usual process where your phone finds SYNC, SYNC will find your phone:



Let me know if this helps or if you have any questions.

Car: Renault Koleos
Phone: Samsung Galaxy Duos S
Works: Yes
Android: 4.0.4
The phone was pairing without a problem, but when connected, radio audio was muted for 3 seconds every 20 seconds.
Using most of your procedure seems to have solved the problem.
I'm not too sure how the phonebook in the car has worked out, but that isn't a problem for me.
Thank you for your efforts.
The Renault dealer and Samsung were of no help at all.
