There's always the display extender option for fitting the empeg.

I'm buying a display extender right now, even though I don't need it for the current car. I'm buying it in anticipation of needing it for some future car.
Hmm... I'm tempted to do this as well, but then again, I hope that some 'future car' of mine will have a car-PC, so then I might be able to run the empeg via weblite.
Sorry, Doug- I don't have any info for you about a Mexico update. I was going to suggest going to the Fit forums, but I see in a google search that you've already done that!
