I have just bought an NX300h, first Lexus I've owned, and overall it is outstanding. The ride over awful London speed bumps and potholes is incredible.
There is only one downside so far. The navigation system is infuriating, The graphics are fine, but entering a postcode takes ages and it's nowhere as good at journey planning as Waze. Is there any App that can be downloaded to the car or any other method I can run Waze through the system? Otherwise I will have to impersonate a minicab driver and rig up the phone to the windscreen, which seems a bit luddite for a brand new car.
