I have a Toyota Celica 5th generation and its speedometer is not working anymore. Same goes for its RPM meter. I tried repairing it through my dealer but unfortunately they were unable to repair it. They tried ordering a new 1 from Toyota Fac in Japan but Toyota is no longer producing the meter.
What can I do? I have an ex RPM meter but is it accurate? and what about the speedometer? rely on GPS? Turbo Timer? ...i dont know
