Thanks, but I decide to use a TomTom for the road, now!
Drive is so poor, for me...
As I got my white N9, now, I can tell you that it's working like a charm with Jabra BT320s, BT360s, and with my Parrot MKi9000 in the car (except dtmf button...).

Live view is amazing, but you can't use it while driving!!!

Well, except for customizing, I love my new phone!!!
