I have the Rave program and i just want to know which file will give me the pdf for land rover discovery I. Most i checked was defender.

 

Should be a pdf in there called rave-lr, open it and click on Discovery.

 

What does the Button with the two lines and something that looks like a skateboard on it mean?

 

It's the cruise control power, its a highway and overpass. The rave file you open is an Adobe file and it should pull up a pdf of the list of vehicles then you click the vehicle you want. It's kinda confusing, you will have surf through it to get familiar with it.
