We are currently looking at a Lexus IS350 X. The only concern I have is that the Navigation system seems a bit clunky and seems to not allow any changes while the car is driving which means the passenger can't make route changes or new routes except if the car is stopped. The car is a February 2013 model and I am wondering whether there is an upgrade that improves the screen image and lock out. I am comparing the system with the BMW 330D system which is just fantastic.
My question are, whether there is an improved system, can you override the lock out or perhaps I am just prejudging and excellent system and that it is better than it initially looks????
