recently I both N80 the problem is when I connect to the car

I believe there is currently a compatibility problem between the Nokia N series phones and the skoda factory bluetooth. Another issue thats been reported is the inability to send the phone contacts to the car kit froma an N95.

yes but my 6630 didnt send the contacts aswell...but I was able to make phone call

I believe there is currently a compatibility problem between the Nokia N series phones and the skoda factory bluetooth.

The issue is only related to the sending of contacts though - in all other respects, the N Series should work fine.

mike_24 - can you try another non-Symbian phone (to confirm the car kit is working ok), and can you try another N80 (to confirm it's not your phone itself with a problem)...?
