THE LAND ROVER RADIOS HAVE A DANGEROUSLY SLOW LATENCY TIME WHEN REACTING TO TOUCH INPUTS. ON SOME OPERATIONS IT TAKE 3-4 SECONDS FOR THE RADIO TO REACT. MOST OPERATIONS ARE IN THE 1-2 SECOND RANGE.

INPUT LATENCY SHOULD NEVER BE THIS EXCESSIVE - IT REQUIRES YOU TO TAKE YOUR EYES OFF THE ROAD REPEATEDLY BECAUSE YOU CAN'T DETERMINE IF THE RADIO/NAV SYSTEM HAS DETECTED YOUR INPUT.
