I own an AVIC-F900 and a Sprint Palm Centro. Whenever I do the phonebook transfer, it copies each contact twice. For instance, if i had 2 (mobile and home) contacts with the name "Bob", it would copy over Bob, Bob, Bob home, and Bob Mobile. Anyone have any tips on how to fix this?

Is there a way to delete all of the contacts off the unit? Maybe they aren't delteing the old when I put new ones in
