I have a NAV system which insists that upon power on it gives a big diclaimer something like:

Only look at the display when it is safe to do so, do not operate the controls while driving etc.etc.

I asked the manufacturer whether this could be disabled and just go straight to the menu screen but no was the answer.

I may have to connect my RedRat 2 to the empeg's serial port and make it send the IR codes to do what I want.
