I have a 2005 GX with the Nav and am considering purchasing an iphone. I noticed that it is not on Lexus's list on Bluetooth phones for this particular vehicle. I was wondering if anyone has had any experience with this.

Any advice is greatly appreciated!

My iPhone synced just fine in my '07. However, I could not get the address book/contacts to do so.

Thanks for the input.

I had this issue with my T Mobile Dash...I actually have an old Motorola V61 that I used to update the contact list even though this phone is no longer active. If you have an old phone, you can set up a temp Bluetooth connection to transfer the data over if you are desperate :0)
