Condition
Some customers or dealers may comment of ghost or phantom touch where random
touch inputs occur with the radio display; and/or the radio display is non-responsive to
touch immediately after having cleaned, wiped, or disinfected the radio display. Either
condition will last the entire ignition cycle. After the radio has gone through a sleep cycle,
the condition would no longer be present.
Cause
The cause of the condition may be the presence of liquid or certain physical touch during
the boot-up sequence that can corrupt the display boot-up for that ignition cycle, causing
false touch input or no touch input to be received until the radio can reboot.
Correction Only clean or disinfect the radio display with the radio on. Always dry the display ensuring
no liquid, debris, or streaks remain.
Service Procedure

or debris.
