Hi,
I have an interesting problem with my 01' GS4 Navi:
First I noticed that top row "AC" button lights are NOT after starting of the car ("Auto", direction, defroster, etc)
Then, when I go to "Climate" mode, onscreen AC control buttons don't work: they are not disabled (greyed out) however, upon selecting, have no effect on AC. In addition temperature (outside/inside) numbers are not displayed. (see the picture below)
To my surpise, though, AC is actually working: I can press "OFF", "AUTO", or any other buttons from the top row and get the expected result.
Also, the trip computer's numbers are gone!!! WTF????
Any idea what it can be caused by?
Thanks!
