hi all,

i have a w810i phone for over a year and i love it (firmware R4EA031)
last month i installed a new "parrot" hands-free car kit (ck3200 ls-color, firmware 2.11).

since then i have a new problem with me phone:
every time i am in my car (while the phone is connected to the hands-free via bluetooth) and someone from my contact list calls me,
my phone freezes/gets stuck (sometimes it shows only white screen) and then gets back to normal after few minutes.
i deleted all contacts from the phone and sim card and the problem was gone.

i restored all the contacts and i get the same problem again -everytime someone from my contact calls me the phone freezes.
i tested the hands-free kit with other phones (nokia n73 and nokia 6500c) and it works perfectly.

i will be glad if someone here knows where to obtain new bluetooth drivers for the phone or any other way to fix this problem except deleting all the contacts which is no applicable.

thank a lot...
