Tesla could make this a profit center. I can't imagine the parts of an MCU (intel atom and LCD screen) are more than $500 and labor to install couldn't be more than $500 as well. I'm sure plenty here would pay ~3K for the upgrade. I'd bet they could have 300 million dollars in revenue and 200 million in pure profit if they made this available and 100,000 cars took them up on it.
