He's asking because when you shut your cab down everything will shut down, including the TV. When you fire your cab up again, if that TV doesn't go back to the same state (meaning turned on) as before you shut the cab down, then you will ALWAYS require the remote for the TV to be handy, to turn the thing back on. Could turn into one of two things:
1. Annoying, in case you run out of battery power and can't start your cab up because you have no screen
or
2. Fatal, as in "I LOST THE FRIGGEN REMOTE!". Now you gotta rip out the TV or hope "Not Me" or "I don't know" return your remote.
