Sweeping and scrolling on the touch screen or confirming a selection feels a bit coarse. Is something broken?

AW: No. The touch screen of this device is needs to comply with its automotive use character, like operation with gloves during winter time or bright sunlight during summer, so a resistive touch screen type is deployed. Resistive screen types respond to pressure only. This in turn means that the simple swipe or tipping on the surface like on a mobile phone (with capacitive screen) does not trigger a desired function. The screen should be operated with a little more finger pressure.
