Hello,
As the TDS GTNXi Pro works in the default C172, then it seems that the issue is not with the TDS GTNXi Pro itself, as well as the 530 not being powered on.
For the A2A Comanche, please check for electrical/avionics power and make sure to turn on all switches, as well as to reset the aircraft in case of failures.
You can, as well, update(check) for the latest version. In case this does not help, we suggest going to A2A for support.
