The included synchronization software, TrueSync, is supposed to work by searching the Outlook Contacts for entries that are members of either the &quot;SIM Card&quot; or &quot;Phonebook&quot; categories, which need to be created by the user. However, in using this software with Outlook 2000 and attempting to download approximately 175 contacts and phone numbers to my Motorola v66, the TrueSync synchronization software would only bring down the first 25 or so. If a contact had only a company name with no person name, then the downloaded contact name was displayed on the v66 by phone number only without a text name. I tried using the included TrueSync Desktop PIM and it didn't work any better. The synchronization software is just plain defective.
