1. A method for adjusting input sensitivity of a touchscreen comprising:
- providing input sensitivity of the touchscreen at a base level;
increasing input sensitivity of the touchscreen above the base level in response to detection of at least one predetermined condition; and
returning input sensitivity of the touchscreen to the base level when atmospheric temperature proximate to the touchscreen is equal to or greater than a first target temperature.

13. A method for adjusting input sensitivity of a touchscreen comprising:
-
providing input sensitivity of the touchscreen at a base level; increasing input sensitivity of the touchscreen above the base level in response to detection of at least one predetermined condition; maintaining input sensitivity of the touchscreen above the base level for a predetermined amount of time measured by a timer; comparing atmospheric temperature proximate to the touchscreen to a first target temperature after expiration of the predetermined amount of time; returning input sensitivity of the touchscreen to the base level when atmospheric temperature proximate to the touchscreen is equal to or greater than the first target temperature; and maintaining input sensitivity of the touchscreen above the base level when atmospheric temperature proximate to the touchscreen is below the first target temperature. - View Dependent Claims (14, 15, 16, 17)

18. A vehicle navigation touchscreen assembly comprising:
-
a touchscreen configured to receive input commands from a user of a vehicle navigation device; and a controller in communication with the touchscreen, the controller configured to adjust input sensitivity of the touchscreen, the controller in communication with a vehicle cabin temperature input resource configured to measure temperature inside a vehicle cabin, and the controller in communication with an external temperature input resource configured to measure temperature outside the vehicle cabin; wherein; the controller is configured to increase input sensitivity of the touchscreen above a base level in response to occurrence of at least one predetermined condition; and the controller is configured to set input sensitivity of the touchscreen at the base level when temperature in the vehicle cabin is greater than or equal to a first target temperature. - View Dependent Claims (19, 20)
