I recently returned from Costa Rica, while my 2005 Prius stayed in New England for a few weeks. Upon return, the radio will turn on, but no sound. The display also has gone quiet and does not beep when I touch the screen, I checked the fuses and looked to see if anything had gnawed through the wiring while away, but everything looked normal.

Any ideas? I'll take it in to the dealer next week, but was hoping someone might have a solution so I don't have to endure a silent drive over Xmas.

thanks.
