| 03:23 | Right click on the box, select Hide option from the context menu. |
| 03:29 | Now we will disable the position tracking and close the route map. |
| 03:34 | As an assignment, |
| 03:35 | Explore the following options, Redisplay, Speedometer and Routing. |
| 03:42 | Now we will learn about the concept of day and night. |
