I've just bought a car which has the Nokia Wireless Car Kit CK-1W already installed. I tried to pair my phone to this, and it finds the car kit ok. However, it asks for a passcode. I've tried the usual '0000' and also '1234', but to no avail. I've googled this and all I can find so far is that the bluetooth code is on a card that came with the original box.
If I hard reset the unit, i'm assuming the bluetooth code won't change... any suggestions as to how to get around this problem??
