Hi,

AFAIK, you need to export your contacts as vCards (version 2.1 should work, i'm not sure if 3.0 will work too) and save them in your n900.

Then, you have to use Petrovich (install it if you don't have it already) and send those vCards to your Parrot.

I don't own a CK3100, but i guess that it has an "receive contacts" option or similar in the menu. You have to select this option before sending the contacts from your n900 to the handsfree device.

Good luck!

P.S: this should work with all Parrot devices.
