I agree! If the IPC isn't flip flopping between the two the button cant be stuck

What happens if you use the English / Metric button and put it in METRIC. See if it still flip flops between the two.

When the HUD reads METRIC, is the IPC reading ENGLISH? When you intentionally press the E/M button, does the HUD properly change?

Does it still flip flop in metric?

I did press the e/m button and it would change accordingly. I did not notice other values changing but i wasnt looking for them either, i was just looking at the speed. The car will be here tomorrow afternoon and I will have a little more time to play with it.

all of the "Gauges" on the DIC will go metric as well as the "Fuel" display, and KMs instead of miles.

Yes the HUD works fine and displays in mph and I can change the right side of the hud to read fuel or oil and temp. None of the buttons on the right side if the wheel work now.

I would disassemble the IPC and make sure that all the connectors for the HUD and BUTTONS are properly connected. Do that before you throw parts at it. If all the connectors are properly connected,
You may just need a new button module.
