For a few months now, the screen on my 700BT in my truck has become less and less responsive to touching. Sometimes I have to press extremely hard, and sometimes I have to press repeatedly to select things on the screen, and when scrolling it'll hang up and instead of scrolling one screen it'll scroll all the way down to the Z entries. I'm starting to think the screen is losing it's ability to read being touched. I've tried recalibrating it, and that didn't help. It seems to be worse in hot weather.
Any ideas on how to fix this? Or am I looking at having to replace the touchscreen or the entire screen?
