Bigaldo, you're initial question was too vague to give any help, i.e. no details about your van, year, model or mileage?
Which LCD above your radio are you talking about? Is your van from 2007 onwards as my radio is set in the middle of the dash with only the vents above it & no LCD display?
If the speedo wasn't showing the mileage, this is usually just a bad connection or a blown bulb, you just pull out the instrument cluster & replace the bulb at the back.
Where exactly is Italian coming up on your display? If this part is from an imported van, you might need to leave it into a place that fixes instrument clusters & get them to change the language, ring a company & ask them.
Believe me, there are loads of posts on here about dash displays not working, you just have to type in the 'right words' in the search box above & you'll come across them, hope this helps.
