I have a RX350 with 5K miles. In the last week, the navigation system has gotten hung right after the engine is started on two different occasions. When this happens, after stopping the engine, and turning on the car again, the system goes into a DVD check. Then things are normal with no error indication.

This might actually be a bug in the firmware of the Nav system, but I wanted to see if anyone else has seen this in their own vehicle.[]

Thanks,
