There was somebody selling device that would over ride "I agree" screen and Nav programing lockout on Prius, but I'm not sure it would work on TCH, especially the new 6.1 version. We need somebody who knows how to program software to make changes on the disc but I haven't seen anything yet. It shouldn't be difficult to find which routine accesses "I agree" memory string and replace conditional jump with hard jump, but I have nothing to disassemble the program, anyone?
