When you go to the hidden screen you get some options and one of them is "Loading" then you go to "Program List" you get this: 1) JP-TSW 2) US-TSW 3) AUS-TSW 4) US-AVN_BT 5) US-AVN_UBT 6) US-AVN_BL 7) CHI-TSW Anyone one know what these functions do?
My guess is that JP, US, AUS, and CHI probably stand for Japan, United States, Australia, and China, respectively. Japan, the United States, Australia, and China all have TSW. The United States apparently also has AVN, of three varieties (BT, UBT, BL). I don't know what that means, but it's a start. I'd guess that it's something that has to be set differently for different countries in which the prius is sold for some reason. ?
Apparently has to do with the Bluetooth/NAV system . . . a little creative googling turned up this: Program list discussion Erin
