If the command/radio options are still functioning properly but the screen itself and the screen is the only issue here this is the screen/display itself that has failed that needs replaced.This has to come complete with a new command/radio unit as it isnt sold seperately and this in some cases can run over $2500 for a new command unit.I have had to replace this before unfortunately for issues like this here.
