Speedometer in 2.5

hi, i’ve got this old speedometer file but its in a old version of blender and i really what to make a car game in 2.5.
Does any1 have a speedometer that works in 2.5 that i could use?
or can some1 please update this file (attached) to 2.5?

i cant use python and really want to learn but don’t have time at the moment so if you could help it would be greatly appreciated.

P.S. I personally don’t know where the file came from as a friend gave it to me (its not mine)
