I have paired my V551 to my mac and to iSync (version 2.2). I go to sync, and it doesn't transfer contacts.. however, if i go into more options and select "Synchronize Email Addresses" the sync works perfectly, although no phone numbers!
if I select "Synchronize Fax Numbers" it works perfectly although no phone numbers
if I select "Synchronize all contacts with phone numbers" All my previous entries are erased from the phone.
if i deselect all 3 options, go back to the main menu, select "Sync all Contacts". Nothing happens.
