Not at all sure what you mean by the first sentence. Certainly, on any map screen you should already have the zoom (+ and -) buttons available.
On any dedicated automotive device, you should be able to be able to select Track Up in Settings so that the map "moves under the car icon" with the track being vertical after each turn. That's opposed to the usual orientation, i.e. having North Up where the car moves on the map (but the map still 'moves' with north at top of screen as the route proceeds)..... and the map still moves under the car icon?
(The car remains in the same place on the map,
and the map moves "under" the car, Direction of travel "up".)
State exactly what you mean by "any file" and the give the model of device you have should you need more assistance.
