HT1351 My fifth generation nano will no longer sync my address book from my Mac. It gives me an error message that "You have no contacts" and asks me if I want to create some. My address book is full of contacts. Sync works for everything else.

Question

My 5th generation nano will no longer Sync my address book from my Mac.  It gives me a message that I have no "Contacts", and asks if I want to create some.  My address book is full of contacts, but for some reason it thinks it is empty.  All the other sync operations work fine including iCal.  My Mac is running OS X 10.7.4.

Answer 1

It sounds like all of your contacts on your Mac running Lion are actually stored up in iCloud. 
Several users running Mac OS X Lion and now ML (and iCloud) have no longer been able to "sync" contacts over to their older iPods models.
A work around is to export all of your contacts out of Address Book as vCards and them copy these vCards into your iPod's Contacts folder.  You'll need to have the Enable Disk Use option ticked from under the iPod's Summary tab in order to browse out to the iPod's Contacts folder via the Finder.
Using your iPod as a storage drive
That's the only "solution" I have been able to use to get contacts to sync/appear on my 5G iPod Video.
