I just noticed today that display on my 2 gen Prius 1500cc model 2010 has stopped showing the yellow bar chart for fuel consumption at 5 mins interval like 5, 10, 15, 20, 25, 30. It is just blank. Although the yellow bar on the right showing current fuel consumption works and also the main screen which has battery animation with wheels also shows the current consumption like 99.9km/h and kms travelled. But just the bars of consumption history have disappeared.
I recently had an mp3 player with DVD player (without screen) attached to the cars main mfd screen. And the radio antenna is also connected to this new player and not the cars built-in radio. Could that have caused this problem? Any help would be appreciated.
