I have a 2008 LS460 and need a new cell. I will use Nextel and need a phone compatible with the bluetooth in the car (I have Nav. system). To use Nextel towers, at least in California, the phone has to start with an "i". There are only 3 phones listed on the Lexus website and I don't like any of them. Lexus says they only tested those phones, so I am hoping that others may work.
