The problem is my brother's phone to get paired with Nissan Qashqai. Had same problem with AquaFish. Somehow managed to pair (to enter car requested PIN 1234 to phone) when car bluetooth device was found as a new device. Now phone already has the car bt listed after the first trial pairing had failed and now does not show option to give PIN code.
Maybe if the current settings are deleted pairing can be done.

I used command line

Code:

devel-su hcitool cc MAC-address

now my phone asks the pin code and pairing was done!

You have to enter the MAC of the cars BT system. You can get it via

Code:

devel-su hcitool scan
