Bluetooth connection

[J-C]

I have a Sony Ericsson Wti19 and I made the update of android to 4.0.4. Since then, I can't make the connection between mobile's bluetooth and car´s bluetooth because when car creates a pin, it doesn't appear a table to put it on the mobile. Why does this happen?

I'm not sure why this happens, but I can help you with a workaround. Go into the contacts app in the phone and try send a contact to the bluetooth kit in your car. This should trigger the box to put in the passcode and they will be paired.
