Occasionally when I use the voice command button to call a contact on my phone, it says the phone book is not ready or contact is not available. When I use Siri to call, the call goes thru ok.

Sometimes when you first start the car, it seems to take a while for the MMI to boot, connect to the phone, and sync the contact list.

Yup, this depends on a few things : how many other BT devices are on the list, how many contacts you have synched, etc...
