I've got a Prius 2nd Gen anniversary model (Japanese language). I want to know where the haddisk is located? I asked this in the 2nd Gen forum and I was advised to ask in this forum since not many 2nd Gen have a harddisk. More Information: The NAV/GPS unit is located under the passengers seat. Songs from the CDs gets recorded to the harddisk. Japanese language, most likely this is a Japanese domestic model. Nav unit and MFD CD/HDD screen images attached. Note: The NAV unit does not have a DVD slot.
