So my 2017 S is showing the dreaded yellow frame on the center screen. I obviously need to get the screen replaced and in reading through the threads on here it appears Tesla is now just swapping screens when possible and not touching the MCU. Since these two are so closely married and I have seen sporadic reports of the entire screen and MCU being replaced when screens were hard to come by I was curious as to whether anyone had been able to accomplish an upgrade to the MCU 2 when this happened to them. I'd be willing to pay some charge for the upgrade if it was indeed possible as Musk indicated in an earlier tweet. I have not checked with an SC on this yet but thought I'd ask here first if anyone had been successful in trying this first. Thanks in advance.
