Pocket PC Sync with Vista

I've tryed to synch my Pocket PC with Vista. I've read that ActiveSync has
been replaced by a new SyncCenter included in Vista but it seems that don't
work for me.

When I put my PocketPC on the cradle a Mobile Center opens and I can see the
files on the PocketPC or open Media Player to synch music. But I can't synch
any contacts or appointments from Outlook as with ActiveSync.

Any one had some experiences with PocketPC's and Windows Vista?

Regards,
Angel.
