Filter phonebook to show in car over bluetooth
I like the way the contacts/people app links the contacts from different sources. For this purpose, I have several accounts syncing contacts (Exchange, Google, Facebook, LinkedIn & Twitter) but only Exchange filtered to show up in the addressbook. When I connect my HTC with my Audi A3, ALL contacts are shown in the car's phonebook. You can imagine that this becomes unreadable (duplicate contacts, useless contacts from Twitter/Google, ...)
How can I force my HTC only to send/show the filtered phonebook on my car's bluetooth phone directory?
Thank you in advance.
