Audio delay on Answer Call via Bluetooth (car)

[ivand]

Hello,

I've found similar question in another thread (http://talk.sonymobile.com/message/274056#274056), but there is no clue..

So, here is the : I connected Xperia Ray to my car's integrated headset via Bluetooth and it (mostly) works fine when making calls.

And here is the problem: for incoming calls, when I pick up the phone there is 5 sec delay till audio coming to car's audio system and I can hear the caller. In the meantime, the caller can hear me, and I can hear him/her in phone, but I connected it to car not to take the phone to my hand.

This was with latest Android 2.3 firmware, and left in the recent 4.0.

Note, that SE T610, T700 and BlackBerry 9800 were connected just fine and responded immediately, so it's not a problem with my car.

Any fix for this?

Thanks,

Ivan

If possible please check if you experience this delay using any other Bluetooth headset as well. By doing this we can check if this is related to the phone in some way.
