I asked Toyota about updating the Gracenote database in my 2016 FRS, which I believe is the same head unit you have. They told me they weren't able to update it unless the unit came with navigation, which it didn't. I tried using other Gracenote databases, but the system would not accept them. Gracenote annoyed me so much that I ended up replacing the head unit with a Pioneer AVH-ZL5150. Problem solved.
