No issues with that portion of the screen. The buttons seem to register my touch, just nothing.
RonS, my line of thinking was maybe I didn't wire something correctly. Parking brake was set, my vehicle has a manual transmission. I should add, I also installed a MicroBypass as well.
If someone who has a 4100 w/o a bypass can chime in, can you not do anything with the LCD while the vehicle is in motion?
