Just bought the IPHONE. I had no problem at all getting it to work with my 2008 Package 3. The Prius gives you a 4 digit code. You put the number in the IPHONE. After maybe 2 minutes youre done. All contacts from the phone are transfered. Also connection is automatic every time you get in the car. My old Katana with Sprint would ask if it was ok to connect everytime. IPHONE and Prius is the way to go. Update 10/27/07 I checked my phone book again and the contents were from my Katana not the IPHONE. IPHONE is paired and the old Katana phone book is in place. I tried to update but it appears there is no way for the IPHONE to push the data to the Prius. I hope they fix this with an update. Sorry everyone I thought it had worked. As someone said earlier that is the $64,000 dollar question. How do you get the IPHONE to push the contacts?
