Mfd Screen Goes Dead During Navigation

Take it back to the dealer. You've got a problem.

 

I've had a similar thing happen once. I've had my prius for a year now and its only happened once. I have an '05 with nav and all that jazz. I was leaving work, got in started up just like normal. I usually keep my MFD on the arrows screen. So I drive to the end of the parking lot up to the light signal. I glance at my MFD and for some reason it was on the "prius" logo again, like right when you start it up. I'm not sure what or why it did it, nothing else went out. No settings were cleared or anything, so I just never bothered with it. So ya its happened to me too...sorta.
I'd say if yours doesnt do it again, I'd just leave it. Things happen with complicated electronics sometimes so maybe it was just a fluke.

 

no worries about the whole car being inoperable. i've driven ours without an mfd it's just the functions that are directed through it- a/c, music, etc.

 

:spy: If you MFD goes out, you are still able to control the radio, A/C, from the steering wheel.

 

Had a similar problem. The MFD simply went black when I changed from one of the energy screens to map. The MFD was totally nonfunctional at first, then the info and display screens began working. Hitting the map button displayed the message: "External device not connected". I pulled over and shut off/restarted the car and everything has worked fine ever since. Jeff

 

Same here today, first time with 08 at about 5000 miles. We were driving along on the Consumption screen, listening to CD. Suddenly the screen went blank and FM came on. At first, no buttons worked; after a minute, I could get the Energy or Consumption screens, but the Energy screen was showing only green battery, and the consumption screen numbers were frozen. However, the 5-minute timer continued to slide the bars off the screen to the left. We were able to restart the CD, and the CD screen came up on the Audio screen, which timed out as usual to the Info display

The Climate button produced "Check the connection to the air conditioner" and the Map button produced "The external device is not connected". None of the steering wheel buttons worked. The touchscreen still worked.

I immediately thought of rebooting it, but we were 50 miles from home and I feared it might not restart, so I waited until back in the driveway. Everything went back to normal on restart, including the fact that the Consumption screen updated the miles driven and MPG to numbers that are apparently correct.

 

Perhaps the MFD soldering problems arn't as fixed as we thought?

 

if it was not a user error. like turning the display off... all mfd, av lan codes are logged. if your really nosey, chances are the mfd logged the issue. i posted the list of mfd codes in the knowledge base

even something simple like playing a dirty or scratched cd, can cause your radio to lose its presets.
