When I started my X today the computer screen reads: Loading of software required please insert suitable cd-rom.

It is not the message that comes up when there is nav disc trouble or one I have ever seen.

Nav unit will eject disc and red light is normal. Radio works, control buttons seem to work but nothing on the screen other than the message. Will not pull up menu or can't see it if it is. I have tried leaving the Xi off for an hour and turning it back on--no change. I have tried removing the nav disc and putting it back --no change. I disconnected the nav unit and plugged it back in--no change.

The only potential cause I can think of is yesterday I hooked the X up to the INPA program for the first time. Perhaps foolishly, I tried a bunch of stuff to see what happened. I didn't notice if the message was there then.

Could I have done something to kill or remove the computer software?

If I erased the software it is wants is it a-- must be done by dealer thing-- or is there a DIY solution?

Please don't bombard me with big strange words--I need the pea brain solution.
