sleis This isn't a "bug" as the function of this view is mainly to see whether or not the vehicle is within the lines when parking.
It would make more sense to allow users to change this but it's unlikely the DUDU team will be able to resolve this as they do not make the SDK used for the 360 app. Most android head units (SPD, FYT, Topway, Choiceways etc) use the same SDK and also have this downside.
You're not the first person to bring this up. There's plenty of threads here asking for this to be fixed but nothing has been done as of yet.
