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" or "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
