I recently acquired a 2001 GTP. I am aware of most of its history but not everything.
The problem. I was driving and noticed that the HUD was displaying km/h instead of mph. I reached over to the DIC and realized all the lights on it were off. I pressed the Eng/Met button and it just beeps, the hud temporarily displayed mph but reverted back to km/h after releasing the eng/met button. I then pressed every button on the DIC and all it does is beep at me, no lights on the display at all. Does not matter which button I press. Eng/met, reset, mode, tcs, does not matter just beeps.
There are some mods but not sure if they would have any bearing on this.
TIA
