Final answer:
To determine which manual ops are unavailable in a navi-system while the vehicle is moving, consult the owner's manual or navigation system's user manual. The system itself may also display a message when certain operations are attempted while in motion.
Step-by-step explanation:
While a vehicle is in motion, certain manual operations in a navigation system may be unavailable to prevent distractions and ensure safe driving. One way to determine which manual ops are unavailable is to consult the vehicle's owner's manual or the navigation system's user manual. These manuals often provide information on the restrictions and limitations while driving, such as disabling certain features or functions.
For example, some navigation systems may disable inputting destinations manually, accessing certain menus, or performing complex operations when the vehicle is in motion.
Another way to find out which manual ops are unavailable is by interacting with the navigation system itself. When attempting to perform certain operations, the system may display a message stating that the action is not possible while the vehicle is moving.
