I installed the debs of mirakels' post #115 and I can succesfully transfer AND sync contacts with my Toyota Prius MY 2010. Later I will try the new obexd in post #118.

Many thanks mirakels!

Just one little thing about the current PBAP implementation: FAX numers are transferred along with mobile numbers, landline numbers etc.

It seems to me that FAX numbers are useless in a car-kit. Would it be possible to filter them out before the contacts are sent by the N900?
