Does anyone know how to sync a Motorola Tundra VA76r with a Mac?

iSync is still being developed, but support for new phone models is provided by the phone's manufacturer and third-party developers through iSync's Phone Plugin architecture that Apple provides.

Unfortunately, unlike Nokia, Samsung, Sony Ericsson and LG, Motorola haven't bothered to release any iSync Plugins for any of their phones, and they don't provide their own syncing solutions for Mac users either.

Often this wouldn't be a problem as a third-party developer could release a plugin if the phone supports the industry standard SyncML protocol. But there is no mention of this support on the Tundra specifications page.

Another alternative is to use Bluetooth to send vCards (industry standard contact files) to the phone exported from the Mac Address Book, but once again, it appears Motorola have not included the required Object Push Bluetooth Profile to allow this to happen. It would definitely be worth trying though, as it may just have been left off the above linked page.

If the phone does support Bluetooth File Transfers you could also use this method to transfer pictures. Just pair the phone using the Bluetooth system preferences pane, and then use the Bluetooth File Exchange application to send/receive files.

Normally the phone stores contacts in an area of memory not browsable by Bluetooth File Exchange.

If you just drag the .vcf file on to the Bluetooth File Exchange application icon, then choose your phone from the list to send to, the phone should accept and store the data appropriately.

To rectify the second problem, try changing the vCard format from 3.0 to 2.1 in Address Book's Preferences. The phone may only recognize the older format.

Some phones will also accept a vCard with multiple contacts in it. If you drag multiple Contacts from Address Book to the desktop, this will create a single vCard containing all contacts. Try sending that to the phone, and if you're lucky, all contacts will be imported in one go. If the phone doesn't import multiple contacts, then you will have to send them one contact per vCard.
