Startup screen

The car animation on the MFD? This is most likely part of the ECU firmware and not user-replaceable.

 

I don't know where or how, but someone did change the startup screen on their Prius. Keep Searching...

 

There's a thread about doing this on the Sat Nav display on the Prime here: Custom startup screen prius prime | PriusChat

 

I only remember some replacing the screen (& sound?) on the Prime, not the Gen 4

 

I searched, but could not come up with the link - but I do remember someone replacing the initial "splash" screen on the Gen 4. At the time I remember thinking that it was not worth the effort since the screen features a white Prius similar to mine already...

 

I've done it - 2½yrs ago - it's in the Entertainment System manual from memory. It only shows for 2 or 3 seconds, so not worth the bother.
