How do I download my iphone phonebook to my 2009 Prius via BT? I have had my 1st Prius for 3 weeks now. And this is my 1st time doing a chat. When I go through my Prius menus, I get to the selection to download the contacts (up to 1000) and then the car menu tells me to tell the phone to send the info. At which time, the iphone BT disconnects from the car. I do not know if the car or the iphone is initiating the disconnect? But when I select "Cancel" on the Car menu, then the iphone reconnects to the car BT. It appears that I could manually add my 150 contacts, but I would rather not.
