I'm not sure what's the english for it but in Bulgaria we call it bord computer. it shows the momental(I hope it is written like that) and the average consumation of fuel, the outside temperature etc. I have seen something like a digital display in the upper center of the dashboard but I am not sure it's that. On one picture i saw it showing "13 degrees"
