I spoke to someone about this. It’s sun damage. The digitizer definitely has to be replaced and maybe the depending on the damage the lcd. now I have another question. I haven’t pulled the MFD to verify the model # but according to Toyota the last 4 of the replacement is 7081 yet all the units I see on eBay that are 7080/7081 are the standard units not the nav unit. I have the nav unit. Is the catalog number incorrect.
the 7081 is the low-def model. It's actually -47081. Has 4 buttons (not 7 like yours) and is non-nav.
I just spent the $180 for a different unit. I think there is a company that buys used MFD for $75 so I may ship the old one to them provided the replacement works. Did all NAV units have Bluetooth
It's relatively important to replace an MFD with an identical model. I have about 15 mfds in my shop. I have two different test plugs for the different models. This is because different models have different pin-outs for receiving power. If the power supplied on the plug wires in your car-side harness does not match with the required 'power in' pins on the mfd, popping noises and smoke will come out of the mfd. I've accidently learned that lesson a couple times by plugging in the wrong test harness.
The replacement I purchased was the same part #. Everything works as it should. Setup Bluetooth without any issues.
