Display MPG on clock display on instrument cluster?

Hey

I just found this youtube video showing what looks like a standard mk4 instrument cluster displaying mpg on the clock screen location. Does anyone know what this is about? Is it a special cluster or a feature that can be enable on all clusters? I would love to have this.

thanks
Daniel.

Interesting , wonder if it's a european cluster thing only and we didn't get it like so many other features, wouldn't mind having that as well

Ours don't have it.

yea, i just checked mine with a flash light, the only thing i saw were the 88:88 for the time and what looks like an antenna with waves coming out of it, any idea what the hell that is?
