Just a quick update to the Prius saga begun yesterday: the dealer tells me that the display system is losing communication with the computer, and that’s why things are going crazy. He ordered the part, and in the mean time I am driving around with the radio turning itself off and on, bizarre things happening with the screen, and a sense of helplessness as I can’t control some aspects of the car without a working display.
Today, in a rather non-commital way, the car finally gave me a little message.
