i'm so frustrated
i tried the bluetooth connection (handsfree) with my nokia mobile at my home pc. everything worked. i could hear the phone call on my pc speakers. so i decided to install the widcomm software 4.1... on my car pc. i connected my phone and everything is ok. my phone shows the connected logo. BUT when i make a phone call i can't hear anything. NO SOUND out of my car pc speakers. i looked at the sound settings, but everything is ok there. i have no idea. sound is ok on my car pc. mp3's are playing.

i have no idea.
hopefully somebody can help me
