Is there a way to adjust the sensitivity on the display screen? Seems I've got to push fairly hard to submit a command.

 

I see from another post that you have a 2011 XJ. The touch screen systems in the 2010-2013 model year XJs are sadly like that. How it got past QA I don't know.

Over years of use now with mine I've found that touching slightly above where you want to touch and holding for a second tends to hit it 95% of the time. The duration seems to be the main requirement, not the amount of pressure applied.

 

If memory serves, I think there is an alignment procedure for the screen. You will have to consult your manual for the instructions.
