Thank you very much for your sympathy.
The radio works in 0.2 MHZ steps and I could be satisfied with it. It just works with this limitation. I can live with that.
Unfortunately, feeding the navigation device with an SD card for Europe is not enough. I have made several enquiries to Lexus and to experts in navigation systems. If anyone has other experiences, please let me know. It would be nice if it were that simple. As far as I understand it, the navigation device must be able to receive other satellites. I have heard of other devices being reprogrammed. Possibly possible in Russia or the Ukraine. That doesn't make it easy, because even contact with Cyrillic languages requires a certain knowledge of the language, which I unfortunately don't have.
A used instrument cluster would be useful for the speed display but difficult to find as the car is not old. The speed dial in miles can be bought in a British shop for 65 pounds. However, not the Km/h display.
That the conversion from Fahrenheit/Celsius should not be feasible is tough. Any small thermometer can do it for little money. Mechanics have told me that Toyota has tricks for changing the temperature display. For example, you have to hold down the temperature selector switch until you hear a beep, then you can change it. I've tried a lot of things in the car, but the display stays at Fahrenheit, as does the pressure display for the tyres at PSI, which isn't all that bad.
If anyone has ever solved similar problems, I would be very grateful to hear more.
Have a good trip.
