I was away from my Prius for three weeks (out of the country) and the first time I switched from the info screen to the Map screen the display went black for maybe 1-2 seconds. When going back to info same thing. But sometimes it is much quicker. It doesn't seem like that was always the case. That normal? Has my memory failed me. Oh yeah, 2005 model.
DVD cache flushed? I've never had it take that long, but I've not left mine idle for that long. Or... the car was dong something else on that bus, delaying the switch? Not sure what, or what bus. Or it needed to stretch.
Once the map went out while I was driving and came back with a different location (I have no clue as to where it was showing). After 30 seconds or so, it corrected itself. Very odd.
