I recently just bought a 2016 is300 f sport with the navigation radio head unit. The screen is completely black (flickers occasionally), but turns on when the car is put in reverse to display the backup camera. The head unit still has power going to it, as ejecting CD's you can still hear the motor, but ALL other functions don't work. I viewed Andy's video on youtube ( ) which pointed towards a faulty data board, but I can't find a salvaged head unit within distance to swap out data boards. I was thinking saving myself a headache in searching for one by buying a brand new data board from Opuradio (https://www.opuradio.com/products/46...vigation-radio), but after shipping, and random fees, it is close to 500! I was just wondering if, before I place an order, anyone has had any experience with this website, a similar problem, or this procedure of swapping out data boards itself. ANY input is appreciated
