• The road system has changed.
• The vehicle is driving on slippery road surfaces such as sand, gravel, or snow.
• The vehicle is traveling on winding roads or long, straight roads.
• The vehicle is approaching a tall building or a large vehicle.
• The surface streets run parallel to a freeway.
• The vehicle has been transferred by a vehicle carrier or a ferry.
• The current position calibration is set incorrectly.
• The vehicle is traveling at high speed.
• The vehicle changes directions more than once, or the vehicle is turning on a turn table in a parking lot.
• The vehicle is entering and/or exiting a parking lot, garage, or a lot with a roof.
• The GPS signal is not received.
• A roof carrier is installed on the vehicle.
• Tire chains are installed on the vehicle.
• The tires are replaced or worn.
• The tire pressure for the tires is incorrect.
• This is the first navigation use after the map data is updated.
• The 12-volt battery has been disconnected for several days.
• The vehicle is driving in heavy traffic where driving is at low speeds, and the vehicle is stopped and started repeatedly.
