Hi guys just had my rvc fitted so just trying to get to grips with the basics. Firstly, I'm guessing the two lines running up 90 degrees from the bottom of the rns represent the width of the vehicle? Also the lines that run across parralel to the bottom of the rns represent distances away from the obstacle, if so what are these distances? It's just hard trying to judge how far iam away from an obstacle! Finally how can I get the display to fill the whole screen? Because at the minute there is a strip running along the bottom and right hand side of the screen with 'screen adjust'. Thanks for your help and sorry for the simple qs!
