I finally found the time to run hcidump with the car-kit of my Toyota Prius MY 2010. Actually, I ran it twice. First time using the obexd package ver 0.28 - I can't quite remember in which post I found that. Second time using the obexd binary compiled by tuxy - see post #179. I turned on the car, paired the N900 with the car-kit, tried to transfer the phone-book to car-kit, dialed a number through the car-kit, tried phone-book transfert again. No joy, no contacts transferred to my car-kit. By reading the dump, I think that the N900 sent a few contacts, but they are not received by the car-kit. The last vcard sent is broken right after "VCARDBEGIN:VCARD". Also there seems to be a CR-LF sequence between "VCARD" and "VERSION:2.1", so the first vcard looks like this: BEGIN:VCARD VERSION:2.1 TEL: N:Surname;Name;;; FN:Surname Name END:VCARDBEGIN:VCARD VERSION:2.1 It continues at the new line after "VERSION:2.1". Any ideas? Thanks for your help anyway!!!
