I have an Rx450h. Brilliant car but I might have pressed the wrong button!
On the navigation screen you can change the range/scale of the map by pressing the small button, up or down, at the front of the 'mouse'.
This usually works without hesitation. However now when I press the button it has no effect and the map appears to have locked onto a scale of 0.5 miles
Is it duff or have I accidently switched some critical function off?
