Nokia 6500 Slide - BT Visorblade HF Car Kit Problem

Hi All

I've got a 6500 slide and am trying to link up to a Visorblade BT car
kit but have had trouble pairing and even if I manage to do that the
connection only remains whilst the Visorblade is switched on. If I
switch it off and then try to re-establish a connection it shows as
connected but no sound comes through the Visorblade if I try to make
or receive a call.

BTW, the Visorblade works fine with a Nokia 6230i and a Samsung G600.

Anyone come across this problem or similar and is there a solution?

Thanks in advance.

Woz.
