I belive it is not possible to transfer the adress book from an iPhone into the RX400. The iPhone is not competable with the system Lexus uses I have learned from checking around. I had a BMW X5 before and it was the the same on that car. The problem I belive is that the phone book on the iPhone is different from other phones. It is on a quite different protocol and containing a lot more information. I have manually entered the numbers that I more frequently uses. But hope someone can make an app that can copy the information and transfer it to the car phonebook.

Hi Yesterday I drove for 2 1/2 hr from Stavanger Norway to Lindesnes this is "country road" up hill and down hill. Speed between 40-55 mph. On that distance I made 38.2 mpg (UK) or 31.8 mpg (US. To and from work at home, short distance I only make 28 mpg (UK) Previously I hade a BMW X5 diesel and to and from work the consumption was more or less the same as the RX400h but long distance on Norwegian rollercoaster roads the RX400h is far better.

Hi I'm new to the forum, great forum. I have a RX400h 2008 with navigation screen. Is it possible to transfere the adress book from an Iphone? Or any one knows about an application that will do it. Belive the information in the Iphone adress book where the phone numbers are also contains a lot more informtion.
