The Map Book is an item located in the driver-side door pocket of the player's car. The Map Book allows the player to choose which route to take between their current town and the next town, and shows various player statistics based on their game progress. A route must be declared in order to cross a border checkpoint. If the player does not select a route before driving up to the checkpoint, the man at the window will ask you to choose a route, and will not open the gate until the player does so.
