Before installing a TV tuner on Prius, it is necessary to disassemble the upholstery at the back of the passenger compartment: lift the trunk compartment, floor and trough, unscrew the left compartment of the trunk, remove the left sidewall of the rear seat, unscrew the bolts on which the left sidewall holds and remove it. The staff tuner is behind the block. We need to remove the unit and the full-time TV tuner and install a new analog TV tuner.
The advantage of this approach is that the ability to control the regular buttons on the handlebar is preserved. In addition, the tuner's replacement automatically turns off the lock on the image at the beginning of the movement.
