The radar scanner (RSB0072-060) of the FR7112 is the same as used on the 1954C/NT NavNet Vx2. You could purchase the required power supply (PSU005) and the 1954C/NT display unit (GP1920C/NT) to make it into a Vx2 radar system. That is the only option that I am aware of other than fixing or replacing your FR7112 with another one.
